You can then hear computer generated music in your radio. this document first describes tempest for eliza, the old program that plays music like your cellphone does when you get a phonecall. then it describes tempest for mp3 which you can use to play mp3 files :-) How does this work ? -------------------- All electronic devices send out eletromagnetic waves. so does your monitor. and your monitor does it all the time. and at very high frequencies. high enough for your short wave AM radio. all you have to do is display the "correct" image on your screen and your monitor will emit the "right" signals. Tempest for Eliza displays pictures on your screen. one for each note in the song. [Note: Markus G. Kuhn's and Ross J. Anderson's paper; "Soft Tempest: Hidden Data Transmission Using Electromagnetic Emanations" was used as a reference when programming Tempest-AM. This paper is a must read before going further testing Tempest-AM. The paper is availabe from http://www.cl.cam.ac.uk/~mgk25/ih98-tempest.pdf I strongly recommend to read the paper thoroughly.] Why this program ? ------------------ You need no additional hardware to understand that it is really possible to observe your computer without physically touching it. (tempest). I wrote this program because it was fun and because it teaches in an amusing way that tempest really exists. i want people to understand that their computers can be observed. And last but not least you can listen to music without a soundcard! More information on Tempest --------------------------- Tempest and electromagnetic radiation is an interesting topic. There aren't very much public literature on this topic. Luckily, there are a few technical papers and web sites on the net that are a must read. Papers to read: o Markus G. Kuhn's and Ross J. Anderson's, "Soft Tempest: Hidden Data Transmission Using Electromagnetic Emanations" http://www.cl.cam.ac.uk/~mgk25/ih98-tempest.pdf o Wim van Eck, "Electromagnetic Radiation from Video Display Units: An Eavesdropping Risk?" http://jya.com/emr.pdf o Christopher Seline, "Eavesdropping On the Electromagnetic Emanations of Digital Equipment: The Laws of Canada, England and the United States" http://www.eff.org/pub/Privacy/Security/tempest_legal.draft Here's a few links to start from: o Ros Anderson's website, is a good starting point and has links to go further. http://www.cl.cam.ac.uk/users/rja14/#Tempest o The Complete, Unofficial TEMPEST Information Page, a great site. A lot of links to other websites and papers. http://www.eskimo.com/~joelm/tempest.html Compiling and runnning ---------------------- you must have libSDL installed. see http://www.devolution.com/~slouken/SDL/ type ./configure make now start X11. make sure that you choose low colordepth this gives much higher speed !!! 8 bpp is optimal. if the cpu runs at 100% the music will slow down, i.e. short tunes will get longer than they usually are. the song will sound bad :) start xvidtune. write down the values of HDisplay VDisplay HTotal Pixel Clock now go and get a short wave AM receiver. (pocket radio, put switch into SW position (if it is named this way;)) dial close to 10 Megahertz now start ./tempest_for_eliza 105000000 1024 768 1400 10000000 songs/forelise pixelclock Hdisplay VDisplay HTotal radio music *1000000 frequency file the program runs in fullscreen. now SLOWLY move a little left and right on your radio to find the 10 Megahertz. You will hear a Song for Eliza from Ludwig van Beethoven the song will be on the radio at multiple frequencies. but the best transmission is at the frequency you gave on the commandline. if your computer makes too much noise on that frequency you could also try some other radio frequencies. it is up to you. now go and try other songs included in the songs/ subdir !! Let's be a spy -------------- Observe your computer from within another room ! take the radio into another room. play with the antenna touch earth connections or other things. just play around. depending on the distance and the quality of your monitor you will hear good voice. i have a TCO'99 monitor and i can still hear GOOD music ! Tempest for MP3 --------------- get your favourite mp3 file to the current directory. let's call it 'foobar.mp3'. make sure you have "amp" and "sox" installed. you must use X11 with 8 bits colordepth. use the old -bpp 8 option to your xserver or the new -fbbpp 8 option if you have a newer Xserver. first we need to find out what the correct sampling rate will be. therefore start: ./tempest_for_mp3 115500000 1024 768 1350 810 1500000 0 20 notexist.raw pixel-clock resy vtotal playmode resx htotal radio-frequency amplification filename note that the vtotal parameter is a new one and must be read from the xvidtune screen! also note that the notexist.raw file does not exist. we just want to see the output of the program, play no music yet. it will display: "audio file frequency should be 13519.890261 Hz" now take this value and convert your mp3 like this: ./mksong.sh 13519 foobar.mp3 cool.raw you can now listen to it with this command: ./tempest_for_mp3 115500000 1024 768 1350 810 1500000 0 20 cool.raw notice the low radio frequency of only 1500 KHz. well... i found out that you actually don't need a short wave radio if you put your antenna close enough to your computer screen. lower frequencies also work. and even nowadays most radios can receive AM waves :) so finally you can send to any radio you have. (but no FM, sorry...) the playmode and amplification parameters control the algorithm for playback. you can choose between playmode 0 and playmode 1. playmode 1 produces a correct AM signal. amplification 1 is correct. if you increase amplification the audio signal will be clipped. but since there is so much disturbing noise anyway, this doesn't matter. you can use playmode 0 to further increase output energy. the signal is not very good anymore then :) but it is louder. the problem is i cannot use the time when the electron beam does the blanking and retrace phase. unfortunately there's no way around this, folks. if your song has heavy basses, you shouldn't over-amplify, because you won't hear the melody while the bass is drumming then... Credits ------- The original idea is from Pekka Riikonen. (see file AUTHORS) he wrote the program tempest-AM-0.9. i used a simplification of his routines to create the signal. tempest_for_eliza-1.0.5/AUTHORS0000644000175000017500000000054607402133263011766 Tempest For Eliza: Erik Thiele http://www.erikyyy.de/ - main code Aaron Lehmann - added fullscreen support Algorithm to create AM signals Pekka Riikonen "tempest" song velAr the meerkat starwars and godfather songs Eric Benoit tempest_for_eliza-1.0.5/COPYING0000644000000000000000000004311007363706725011730 GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library.

The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, a file `config.cache' that saves the results of its tests to speed up reconfiguring, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.in' is used to create `configure' by a program called `autoconf'. You only need `configure.in' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. You can give `configure' initial values for variables by setting them in the environment. Using a Bourne-compatible shell, you can do that on the command line like this: CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure Or on systems that have the `env' program, you can do it like this: env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you must use a version of `make' that supports the `VPATH' variable, such as GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. If you have to use a `make' that does not supports the `VPATH' variable, you have to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. Installation Names ================== By default, `make install' will install the package's files in `/usr/local/bin', `/usr/local/man', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PATH'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you give `configure' the option `--exec-prefix=PATH', the package will use PATH as the prefix for installing programs and libraries. Documentation and other data files will still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=PATH' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Specifying the System Type ========================== There may be some features `configure' can not figure out automatically, but needs to determine by the type of host the package will run on. Usually `configure' can figure that out, but if it prints a message saying it can not guess the host type, give it the `--host=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name with three fields: CPU-COMPANY-SYSTEM See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the host type. If you are building compiler tools for cross-compiling, you can also use the `--target=TYPE' option to select the type of system they will produce code for and the `--build=TYPE' option to select the type of system on which you are compiling the package. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Operation Controls ================== `configure' recognizes the following options to control how it operates. `--cache-file=FILE' Use and save the results of the tests in FILE instead of `./config.cache'. Set FILE to `/dev/null' to disable caching, for debugging `configure'. `--help' Print a summary of the options to `configure', and exit. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `--version' Print the version of Autoconf used to generate the `configure' script, and exit. `configure' also accepts some other, not widely useful, options. tempest_for_eliza-1.0.5/Makefile.am0000644000175000017500000000037707402214005012746 SUBDIRS=songs EXTRA_DIST=mksong.sh INCLUDES=@SDL_CFLAGS@ bin_PROGRAMS=tempest_for_eliza tempest_for_mp3 tempest_for_eliza_SOURCES=player.cpp tempest_for_eliza_LDADD=@SDL_LIBS@ tempest_for_mp3_SOURCES=mp3player.cpp tempest_for_mp3_LDADD=@SDL_LIBS@ tempest_for_eliza-1.0.5/NEWS0000644000175000017500000000000007402133263011376 tempest_for_eliza-1.0.5/acinclude.m40000644000175000017500000002173207402133263013107 AC_DEFUN(AC_YYY_CC_CXX_BEGIN, [ AC_ARG_ENABLE(debug, [ --enable-debug do not strip binaries but add debug info], yyydebug=yes, yyydebug=no) AC_ARG_ENABLE(profiling, [ --enable-profiling every program creates profiling output], yyyprofiling=yes, yyyprofiling=no) AC_ARG_ENABLE(nooptimizing, [ --enable-nooptimizing do not optimize], yyynooptimizing=yes, yyynooptimizing=no) AC_ARG_ENABLE(nowarnerror, [ --enable-nowarnerror do not stop make if compiler warning], yyynowarnerror=yes, yyynowarnerror=no) AC_ARG_WITH(cccxxpre, [ --with-cccxxpre=x add at beginning of C and C++ options], yyycccxxpre="$withval",yyycccxxpre="") AC_ARG_WITH(cccxxpost, [ --with-cccxxpost=x add at end of C and C++ options], yyycccxxpost="$withval",yyycccxxpost="") AC_ARG_WITH(ldpre, [ --with-ldpre=x add at beginning of linker options], yyyldpre="$withval",yyyldpre="") AC_ARG_WITH(ldpost, [ --with-ldpost=x add at end of linker options], yyyldpost="$withval",yyyldpost="") YYY_CFLAGS="" YYY_CXXFLAGS="" YYY_LDFLAGS="" ]) AC_DEFUN(AC_YYY_CC_INIT, [ AC_ARG_WITH(ccpre, [ --with-ccpre=x add at beginning of C options], yyyccpre="$withval",yyyccpre="") AC_ARG_WITH(ccpost, [ --with-ccpost=x add at end of C options], yyyccpost="$withval",yyyccpost="") # if not set then set it as empty, so that AC_PROG_CC doesn't set it if test "$CFLAGS" = "";
