(TEA_MAKE_LIB): Enhanced to check for MSVC that requires manifests and auto-embed it into proj DLL via MAKE_SHARED_LIB. Also define VC_MANIFEST_EMBED_DLL and VC_MANIFEST_EMBED_EXE that do the same magic in case it is needed for extended TEA projects. 2010-08-16 Jeff Hobbs *** Bump to TEA_VERSION 3.9 *** If upgrading from TEA_VERSION 3.8, copy over tcl.m4, change TEA_INIT to use 3.9 and reconfigure (ac-2.59+). BUILD_${PACKAGE_NAME} will be auto-defined on Windows for correct setting of TCL_STORAGE_CLASS. TEA_LOAD_CONFIG users should remove the SHLIB_LD_LIBS setting done in configure.in (LIBS will be automagically populated by TEA_LOAD_CONFIG). TEA_EXPORT_CONFIG has been added for ${pkg}Config.sh creators SHLIB_LD_FLAGS was deprecated a while ago, remove it if it is still in your Makefile.in. * tcl.m4: add /usr/lib64 to set of auto-search dirs. [Bug 1230554] Auto-define BUILD_$PACKAGE_NAME so users don't need to. This needs to correspond with $pkg.h define magic for TCL_STORAGE_CLASS. Auto-define CLEANFILES. Users can expand it. (SHLIB_LD_LIBS): define to '${LIBS}' default and change it only if necessary. Platforms not using this may simply not work or have very funky linkers. (TEA_LOAD_CONFIG): When loading config for another extension, auto-add stub libraries found with TEA_ADD_LIBS. Eases configure.in for modules like itk and img::*. (TEA_EXPORT_CONFIG): Add standardized function for exporting a ${pkg}Config.sh. See use by img::* and itcl. 2010-08-12 Jeff Hobbs *** Bump to TEA_VERSION 3.8 *** If upgrading from TEA_VERSION 3.7, copy over tcl.m4, change TEA_INIT to use 3.8 and reconfigure (ac-2.59+). No other changes should be necessary. * tcl.m4: remove more vestigial bits from removed platforms. Add back SCO_SV-3.2*. Remove use of DL_LIBS and DL_OBJS and related baggage - these are only needed by the core to support 'load'. Allow for macosx in TEA_ADD_SOURCES. Correct check for found_xincludes=no in TEA_PATH_UNIX_X. 2010-08-11 Jeff Hobbs * tcl.m4: remove the following old platform configurations: UNIX_SV*|UnixWare-5*, SunOS-4.*, SINIX*5.4*, SCO_SV-3.2*, OSF1-1.*, NEXTSTEP-*, NetBSD-1.*|FreeBSD-[[1-2]].*, MP-RAS-*, IRIX-5.*, HP-UX-*.08.*|HP-UX-*.09.*|HP-UX-*.10.*, dgux*, BSD/OS-2.1*|BSD/OS-3* (AIX): drop AIX-pre4 support and use of ldAix, use -bexpall/-brtl 2010-07-05 Jan Nijtmans * tcl.m4: [Patch #1055668] removal of exported internals from tclInt.h (EXTERN macro) 2010-04-14 Jan Nijtmans * tcl.m4 - Backport a lot of quoting fixes from tcl8.6/unix/tcl.m4 - Fix determination of CYGPATH for CYGWIN With those fixes, itcl and tdbc compile fine with CYGWIN 2010-04-06 Jan Nijtmans * install-sh [Bug 2982540] configure and install* script files should always have LF 2010-02-19 Stuart Cassoff * tcl.m4: Correct compiler/linker flags for threaded builds on OpenBSD. 2010-01-19 Jan Nijtmans * tcl.m4: Detect CYGWIN variant: win32 or unix 2010-01-03 Donal K.

[Bug #1997760] (TEA_PRIVATE_TCL_HEADERS, TEA_PRIVATE_TK_HEADERS): allow for finding the headers installed in the public areas, e.g. a result of make install-private-headers. [Bug #1631922] 2008-08-12 Daniel Steffen * tcl.m4 (Darwin): link shlib with current and compatiblity version flags; look for libX11.dylib when searching for X11 libraries. 2008-06-12 Daniel Steffen * tcl.m4 (SunOS-5.11): fix 64bit amd64 support with gcc & Sun cc. 2008-03-27 Daniel Steffen * tcl.m4 (SunOS-5.1x): fix 64bit support for Sun cc. [Bug 1921166] 2008-02-01 Donal K. Fellows * tcl.m4 (TEA_CONFIG_CFLAGS): Updated to work at least in part with more modern VC versions. Currently just made the linker flags more flexible; more work may be needed. 2007-10-26 Daniel Steffen * tcl.m4 (Darwin): add support for 64-bit X11. 2007-10-23 Jeff Hobbs *** Tagged tea-3-branch to start TEA 4 development on HEAD *** 2007-09-17 Joe English * tcl.m4: use '${CC} -shared' instead of 'ld -Bshareable' to build shared libraries on current NetBSDs [Bug 1749251]. 2007-09-15 Daniel Steffen * tcl.m4: replace all direct references to compiler by ${CC} to enable CC overriding at configure & make time. (SunOS-5.1x): replace direct use of '/usr/ccs/bin/ld' in SHLIB_LD by 'cc' compiler driver. 2007-08-08 Jeff Hobbs * tcl.m4: check Ttk dir for Tk private headers (8.5). Add some comments to other bits. 2007-06-25 Jeff Hobbs * tcl.m4 (TEA_PROG_TCLSH, TEA_PROG_WISH): move where / is added. 2007-06-13 Jeff Hobbs * tcl.m4: fix --with-tkinclude alignment.

[Bug 1586861] (Darwin): add -isysroot and -mmacosx-version-min flags to CPPFLAGS when present in CFLAGS to avoid discrepancies between what headers configure sees during preprocessing tests and compiling tests. 2006-12-19 Daniel Steffen * tcl.m4 (Darwin): --enable-64bit: verify linking with 64bit -arch flag succeeds before enabling 64bit build. 2006-12-16 Daniel Steffen * tcl.m4 (Linux): fix previous change to use makefile variable LDFLAGS_DEFAULT instead of LDFLAGS in SHLIB_LD, to ensure linker flags in sampleextension Makefile are picked up. 2006-11-26 Daniel Steffen * tcl.m4 (Linux): --enable-64bit support. [Patch 1597389], [Bug 1230558] 2006-08-18 Daniel Steffen * tcl.m4 (Darwin): add support for --enable-64bit on x86_64, for universal builds including x86_64 and for use of -mmacosx-version-min instead of MACOSX_DEPLOYMENT_TARGET. For Tk extensions, remove 64-bit arch flags from CFLAGS like in the Tk configure, as neither TkAqua nor TkX11 can be built for 64-bit at present. 2006-03-28 Jeff Hobbs * tcl.m4: []-quote AC_DEFUN functions. (TEA_PATH_TKCONFIG): Fixed Windows-specific check for tkConfig.sh. (TEA_MAKE_LIB): Prepend 'lib' for Windows-gcc configs. 2006-03-07 Joe English * tcl.m4: Set SHLIB_LD_FLAGS='${LIBS}' on NetBSD, as per the other *BSD variants [Bug 1334613]. 2006-01-25 Jeff Hobbs *** Bump to TEA version 3.5 *** * tcl.m4: keep LD_SEARCH_FLAGS and CC_SEARCH_FLAGS synchronous with core tcl.m4 meaning. 2006-01-24 Daniel Steffen * tcl.m4 (Darwin): use makefile variable LDFLAGS_DEFAULT instead of LDFLAGS in SHLIB_LD, to ensure linker flags in sampleextension Makefile are picked up. [Bug 1403343] 2006-01-23 Jeff Hobbs * tcl.m4: add C:/Tcl/lib and C:/Progra~1/Tcl/lib dirs to check for *Config.sh on Windows. [Bug 1407544] 2006-01-23 Daniel Steffen * tcl.m4 (Darwin): for Tk extensions, remove -arch ppc64 from CFLAGS like in the Tk configure, as neither TkAqua nor TkX11 can be built for 64bit at present (no 64bit GUI libraries). 2006-01-22 Jeff Hobbs * tcl.m4: restore system=windows on Windows. Remove error if 'ar' isn't found (it may not be on Windows). Do not add -lxnet or define _XOPEN_SOURCE on HP-UX by default. Ensure the C|LDFLAGS_DEFAULT gets the fully sub'd value at configure time. 2006-01-10 Daniel Steffen * tcl.m4: add caching, use AC_CACHE_CHECK instead of AC_CACHE_VAL where possible, consistent message quoting, sync relevant tcl/unix/tcl.m4 HEAD changes and gratuitous formatting differences (notably sunc removal of support for for ancient BSD's, IRIX 4, RISCos and Ultrix by kennykb), Darwin improvements to TEA_LOAD_*CONFIG to make linking work against Tcl/Tk frameworks installed in arbitrary location, change TEA_PROG_* search order (look in *_BIN_DIR parents before *_PREFIX). 2006-01-05 Jeff Hobbs * tcl.m4: add dkf's system config refactor 2006-01-04 Jeff Hobbs * tcl.m4: remove extraneous ' that causes bash 3.1 to choke 2005-12-19 Joe English * tcl.m4 (TEA_PATH_TCLCONFIG &c): Look for tclConfig.sh &c in ${libdir}, where they are installed by default [Patch #1377407]. 2005-12-05 Don Porter * tcl.m4 (TEA_PUBLIC_*_HEADERS): Better support for finding header files for uninstalled Tcl and Tk. 2005-12-02 Jeff Hobbs * tcl.m4: correctly bump TEA_VERSION var to 3.4 2005-12-01 Daniel Steffen * unix/tcl.m4 (Darwin): fixed error when MACOSX_DEPLOYMENT_TARGET unset 2005-11-29 Jeff Hobbs * tcl.m4: *** Bump to TEA version 3.4 *** Add Windows x64 build support. Remove TEA_PATH_NOSPACE and handle the problem with ""s where necessary - the macro relied on TCLSH_PROG which didn't work for cross-compiles. 2005-11-27 Daniel Steffen * tcl.m4 (Darwin): add 64bit support, add CFLAGS to SHLIB_LD to support passing -isysroot in env(CFLAGS) to configure (flag can't be present twice, so can't be in both CFLAGS and LDFLAGS during configure), don't use -prebind when deploying on 10.4. (TEA_ENABLE_LANGINFO, TEA_TIME_HANDLER): add/fix caching. 2005-10-30 Daniel Steffen * tcl.m4: fixed two tests for TEA_WINDOWINGSYSTEM = "aqua" that should have been for `uname -s` = "Darwin" instead; added some missing quoting. (TEA_PROG_TCLSH, TEA_PROG_WISH): fix incorrect assumption that install location of tclConfig.sh/tkConfig.sh allows to determine the tclsh/wish install dir via ../bin. Indeed tcl/tk can be configured with arbitrary --libdir and --bindir (independent of prefix) and such a configuration is in fact standard with Darwin framework builds. At least now also check ${TCL_PREFIX}/bin resp. ${TK_PREFIX}/bin for presence of tclsh resp. wish (if tcl/tk have been configured with arbitrary --bindir, this will still not find them, for a general solution *Config.sh would need to contain the values of bindir/libdir/includedir passed to configure). 2005-10-07 Jeff Hobbs * tcl.m4: Fix Solaris 5.10 check and Solaris AMD64 64-bit builds. 2005-10-04 Jeff Hobbs * tcl.m4 (TEA_PRIVATE_TCL_HEADERS): add / to finish sed macro (TEA_ENABLE_THREADS): don't check for pthread_attr_setstacksize func 2005-09-13 Jeff Hobbs * tcl.m4: *** Update to TEA version 3.3 *** define TEA_WINDOWINGSYSTEM in TEA_LOAD_TKCONFIG. Make --enable-threads the default (users can --disable-threads). Improve AIX ${CC}_r fix to better check existing ${CC} value. Do the appropriate evals to not require the *TOP_DIR_NATIVE vars be set for extensions that use private headers. Make aqua check for Xlib compat headers the same as win32. 2005-07-26 Mo DeJong * tcl.m4 (TEA_PROG_TCLSH, TEA_BUILD_TCLSH, TEA_PROG_WISH, TEA_BUILD_WISH): Remove TEA_BUILD_TCLSH and TEA_BUILD_WISH because of complaints that it broke the build when only an installed version of Tcl was available at extension build time. The TEA_PROG_TCLSH and TEA_PROG_WISH macros will no longer search the path at all. The build tclsh or installed tclsh shell will now be found by TEA_PROG_TCLSH. 2005-07-24 Mo DeJong * tcl.m4 (TEA_PROG_TCLSH, TEA_BUILD_TCLSH, TEA_PROG_WISH, TEA_BUILD_WISH): Split confused search for tclsh on PATH and build and install locations into two macros. TEA_PROG_TCLSH and TEA_PROG_WISH search the system PATH for an installed tclsh or wish. The TEA_BUILD_TCLSH and TEA_BUILD_WISH macros determine the name of tclsh or wish in the Tcl or Tk build directory even if tclsh or wish has not yet been built. [Tcl bug 1160114] [Tcl patch 1244153] 2005-06-23 Daniel Steffen * tcl.m4 (TEA_PRIVATE_TK_HEADERS): add ${TK_SRC_DIR}/macosx to TK_INCLUDES when building against TkAqua. * tcl.m4 (TEA_PATH_X): fixed missing comma in AC_DEFINE * tcl.m4: changes to better support framework builds of Tcl and Tk out of the box: search framework install locations for *Config.sh, and if in presence of a framework build, use the framework's Headers and PrivateHeaders directories for public and private includes. [FR 947735] 2005-06-18 Daniel Steffen * tcl.m4 (Darwin): add -headerpad_max_install_names to LDFLAGS to ensure we can always relocate binaries with install_name_tool. 2005-06-04 Daniel Steffen * tcl.m4 (TEA_PATH_X): for TEA_WINDOWINGSYSTEM == aqua, check if xlib compat headers are available in tkheaders location, otherwise add xlib sourcedir to TK_XINCLUDES. 2005-04-25 Daniel Steffen * tcl.m4: added AC_DEFINE* descriptions (from core tcl.m4) to allow use with autoheader. (Darwin): added configure checks for recently added linker flags -single_module and -search_paths_first to allow building with older tools (and on Mac OS X 10.1), use -single_module in SHLIB_LD. (TEA_MISSING_POSIX_HEADERS): added caching of dirent.h check. (TEA_BUGGY_STRTOD): added caching (sync with core tcl.m4). 2005-03-24 Jeff Hobbs * tcl.m4 (TEA_TCL_64BIT_FLAGS): use Tcl header defaults for wide int type only on Windows when __int64 is detected as valid. 2005-03-24 Don Porter * README.txt: Update reference to "SC_* macros" to "TEA_* macros". * tcl.m4: Incorporated recent improvements in SC_PATH_TCLCONFIG and SC_PATH_TKCONFIG into TEA_PATH_TCLCONFIG and TEA_PATH_TKCONFIG. Corrected search path in TEA_PATH_CONFIG and added AC_SUBST($1_BIN_DIR) to TEA_LOAD_CONFIG so that packages that load the configuration of another package can know where they loaded it from. 2005-03-18 Jeff Hobbs * tcl.m4 (TEA_CONFIG_CFLAGS): correct 2005-03-17 change to have variant LD_SEARCH_FLAGS for gcc and cc builds. * tcl.m4 (TEA_PROG_TCLSH, TEA_PROG_WISH): correct x-compile check. 2005-03-17 Jeff Hobbs * tcl.m4: Correct gcc build and HP-UX-11. 2005-02-08 Jeff Hobbs * tcl.m4 (TEA_ADD_LIBS): don't touch lib args starting with -. (TEA_CONFIG_CFLAGS): only define _DLL for CE in shared build. (TEA_MAKE_LIB): set RANLIB* to : on Windows (it's not needed). 2005-02-01 Jeff Hobbs * tcl.m4: redo of 2005-01-27 changes to correctly handle paths with spaces. Win/CE and Win/64 builds now require a prebuilt tclsh to handle conversion to short pathnames. This is done in the new TEA_PATH_NOSPACE macro. For Win/CE|64, make CC just the compiler and move the necessary includes to CFLAGS. (TEA_CONFIG_CFLAGS): Add Solaris 64-bit gcc build support. (TEA_PROG_TCLSH, TEA_PROG_WISH): Allow TCLSH_PROG and WISH_PROG to be set in the env and prevent resetting. (TEA_ADD_LIBS): On Windows using GCC (mingw), convert foo.lib args to -lfoo, for use with mingw. *** POTENTIAL INCOMPATABILITY *** (TEA_CONFIG_CFLAGS): Fix AIX gcc builds to work out-of-box. Bumped TEA to 3.2. 2005-01-27 Jeff Hobbs * tcl.m4: remove cygpath calls to support msys. Update base CE build assumption to "420,ARMV4,ARM,Pocket PC 2003". Make STLIB_LD use $LINKBIN -lib. 2005-01-25 Daniel Steffen * tcl.m4 (Darwin): fixed bug with static build linking to dynamic library in /usr/lib etc instead of linking to static library earlier in search path. [Tcl Bug 956908] Removed obsolete references to Rhapsody. 2004-12-29 Jeff Hobbs * tcl.m4: Updates for VC7 compatibility, fixing CFLAGS and LDFLAGS options, using better default -O levels. [Bug 1092952, 1091967] 2004-12-29 Joe English * tcl.m4: Do not use ${DBGX} suffix when building shared libraries [patch #1081595, TIP #34] 2004-09-07 Jeff Hobbs * tcl.m4 (TEA_CONFIG_CFLAGS): support eVC4 Win/CE builds 2004-08-10 Jeff Hobbs * tcl.m4 (TEA_INIT, TEA_PREFIX): update handling of exec_prefix to work around subdir configures since autoconf only propagates the prefix (not exec_prefix). 2004-07-23 Daniel Steffen * tcl.m4 (TEA_CONFIG_CFLAGS): Darwin section: brought inline with Tcl 8.5 HEAD config, removed core specific & obsolete settings. 2004-07-22 Jeff Hobbs * tcl.m4 (TEA_PATH_X): check in TK_DEFS for MAC_OSX_TK to see if we are compiling on Aqua. Add TEA_WINDOWINGSYSTEM var that reflects 'tk windowingsystem' value. 2004-07-16 Jeff Hobbs * tcl.m4 (TEA_ENABLE_THREADS): force a threaded build when building against a threaded core. (CFLAGS_WARNING): Remove -Wconversion for gcc builds (TEA_CONFIG_CFLAGS): Reorder configure.in for better 64-bit build configuration, replacing EXTRA_CFLAGS with CFLAGS. [Bug #874058] Update to latest Tcl 8.5 head config settings. Call this TEA version 3.1. 2004-04-29 Jeff Hobbs * tcl.m4 (TEA_TCL_64BIT_FLAGS): replace AC_TRY_RUN test with AC_TRY_COMPILE for the long vs. long long check. (kenny) 2004-04-26 Jeff Hobbs * tcl.m4 (TEA_TCL_64BIT_FLAGS): update against core tcl.m4 to define TCL_WIDE_INT_IS_LONG if 'using long'. 2004-03-19 Jeff Hobbs * tcl.m4: correct Windows builds getting LDFLAGS info in MAKE_LIB 2004-02-11 Jeff Hobbs * tcl.m4: correct TCL_INCLUDES for private headers on Windows - it doesn't need the eval. 2004-02-10 Jeff Hobbs * tcl.m4: don't require TK_INCLUDES and TCL_INCLUDES to have the DIR_NATIVE vars defined when using private headers on unix. Allow $... to TEA_ADD_SOURCES for constructs like TEA_ADD_SOURCES([\$(WIN_OBJECTS)]), that allow the developer to place more in the Makefile.in. tkUnixPort.h checks for HAVE_LIMITS_H, so do both HAVE and CHECK on limits.h 2003-12-10 Jeff Hobbs * Makefile.in: added TEA_ADD_LIBS, TEA_ADD_INCLUDES and * configure: TEA_ADD_CFLAGS to configurable parameters with * configure.in: PKG_* equivs in the Makefile. This allows the * tclconfig/tcl.m4: user to worry less about actual magic VAR names. Corrected Makefile.in to note that TEA_ADD_TCL_SOURCES requires exact file names. 2003-12-09 Jeff Hobbs * tcl.m4: updated OpenBSD support based on [Patch #775246] (cassoff) 2003-12-05 Jeff Hobbs * configure: * configure.in: * Makefile.in (VPATH): readd $(srcdir) to front of VPATH as the first part of VPATH can get chopped off. Change .c.$(OBJEXT) rule to .c.@OBJEXT@ to support more makes. * tclconfig/tcl.m4: add TEA_ADD_STUB_SOURCES to support libstub generation and TEA_ADD_TCL_SOURCES to replace RUNTIME_SOURCES as the way the user specifies library files. 2003-12-03 Jeff Hobbs * configure: Update of TEA spec to (hopefully) simplify * configure.in: some aspects of TEA by making use of more * Makefile.in: AC 2.5x features. Use PACKAGE_NAME (instead * generic/tclsample.c: of PACKAGE) and PACKAGE_VERSION (instead of * tclconfig/tcl.m4: VERSION) arguments to AC_INIT as the TEA package name and version. Provide a version argument to TEA_INIT - starting with 3.0. Drop all use of interior shell substs that older makefiles didn't like. Use PKG_* naming convention instead. Move specification of source files and public headers into configure.in with TEA_ADD_SOURCES and TEA_ADD_HEADERS. These will be munged during ./configure into the right obj file names (no $(SOURCES:.c=.obj) needed). There is almost nothing that should be touched in Makefile.in now for the developer. May want to add a TEA_ADD_TCL_SOURCES for the RUNTIME_SOURCES that remains. Use SHLID_LD_FLAGS (instead of SHLID_LDFLAGS) as Tcl does. Only specify the user requested LDFLAGS/CFLAGS in the Makefile, don't mention the _OPTIMIZE/_DEBUG variants. 2003-10-15 Jeff Hobbs * tcl.m4: create a TEA_SETUP_COMPILER_CC the precedes the TEA_SETUP_COMPILER macro. They are split so the check for CC occurs before any use of CC. Also add AC_PROG_CPP to the compiler checks. 2003-10-06 Jeff Hobbs * tcl.m4: Updated for autoconf 2.5x prereq. Where TCL_WIDE_INT_TYPE would be __int64, defer to the code checks in tcl.h, which also handles TCL_LL_MODIFIER* properly. 2003-04-22 Jeff Hobbs * tcl.m4: correct default setting of ARCH for WinCE builds. Correct \ escaping for CE sed macros. 2003-04-10 Jeff Hobbs * tcl.m4: replace $(syscal) construct with older `syscall` for systems where sh != bash. 2003-04-09 Jeff Hobbs * tcl.m4 (TEA_WITH_CELIB): add --enable-wince and --with-celib options for Windows/CE compilation support. Requires the Microsoft eMbedded SDK and Keuchel's celib emulation layer. 2003-02-18 Jeff Hobbs * tcl.m4 (TEA_ENABLE_THREADS): Make sure -lpthread gets passed on the link line when checking for the pthread_attr_setstacksize symbol. (dejong) * tcl.m4 (TEA_SETUP_COMPILER): added default calls to TEA_TCL_EARLY_FLAGS, TEA_TCL_64BIT_FLAGS, TEA_MISSING_POSIX_HEADERS and TEA_BUGGY_STRTOD. 2003-02-14 Jeff Hobbs * tcl.m4: correct HP-UX ia64 --enable-64bit build flags 2003-01-29 Jeff Hobbs * tcl.m4: check $prefix/lib as well as $exec_prefix/lib when looking for tcl|tkConfig.sh, as this check is done before we would set exec_prefix when the user does not define it. 2003-01-21 Mo DeJong * tcl.m4 (TEA_CONFIG_CFLAGS): Fix build support for mingw, the previous implementation would use VC++ when compiling with mingw gcc. Don't pass -fPIC since gcc always compiles pic code under win32. Change some hard coded cases of gcc to ${CC}. 2002-10-15 Jeff Hobbs * tcl.m4: move the CFLAGS definition from TEA_ENABLE_SHARED to TEA_MAKE_LIB because setting too early confuses other AC_* macros. Correct the HP-11 SHLIB_LD_LIBS setting. * tcl.m4: add the CFLAGS definition into TEA_ENABLE_SHARED and make it pick up the env CFLAGS at configure time. 2002-10-09 Jeff Hobbs * tcl.m4: add --enable-symbols=mem option to enable TCL_MEM_DEBUG. Improved AIX 64-bit build support, allow it on AIX-4 as well. Enable 64-bit HP-11 compilation with gcc. Enable 64-bit IRIX64-6 cc build support. Correct FreeBSD thread library linkage. Add OSF1 static build support. Improve SunOS-5 shared build SHLIB_LD macro. 2002-07-20 Zoran Vasiljevic * tcl.m4: Added MINGW32 to list of systems checked for Windows build. Also, fixes some indentation issues with "--with-XXX" options. 2002-04-23 Jeff Hobbs * tcl.m4 (TEA_ENABLE_THREADS): added USE_THREAD_ALLOC define to use new threaded allocatory by default on Unix for Tcl 8.4. (TEA_CONFIG_CFLAGS): corrected LD_SEARCH_FLAGS for FreeBSD-3+. 2002-04-22 Jeff Hobbs * tcl.m4 (TEA_SETUP_COMPILER): removed call to AC_CYGWIN so that we can use autoconf 2.5x as well as 2.13. This prevents us from being able to warn against the use of cygwin gcc at configure time, but allows autoconf 2.5x, which is what is shipped with most newer systems. 2002-04-11 Jeff Hobbs * tcl.m4: Enabled COFF as well as CV style debug info with --enable-symbols to allow Dr. Watson users to see function info. More info on debugging levels can be obtained at: http://msdn.microsoft.com/library/en-us/dnvc60/html/gendepdebug.asp 2002-04-03 Jeff Hobbs * tcl.m4: change all SC_* macros to TEA_*. The SC_ was for Scriptics, which is no more. TEA represents a better, independent prefix that won't need changing. Added preliminary mingw gcc support. [Patch #538772] Added TEA_PREFIX macro that handles defaulting the prefix and exec_prefix vars to those used by Tcl if none were specified. Added TEA_SETUP_COMPILER macro that encompasses the AC_PROG_CC check and several other basic AC_PROG checks needed for making executables. This greatly simplifies user's configure.in files. Collapsed AIX-5 defines into AIX-* with extra checks for doing the ELF stuff on AIX-5-ia64. Updated TEA_ENABLE_THREADS to take an optional arg to allow switching it on by default (for Thread) and add sanity checking to warn the user if configuring threads incompatibly. 2002-03-29 Jeff Hobbs * tcl.m4: made sure that SHLIB_LDFLAGS was set to LDFLAGS_DEFAULT. Removed --enable-64bit support for AIX-4 because it wasn't correct. Added -MT or -MD Windows linker switches to properly support symbols-enabled builds. 2002-03-28 Jeff Hobbs * tcl.m4: called AC_MSG_ERROR when SC_TEA_INIT wasn't called first instead of calling it as that inlines it each time in shell code. Changed Windows CFLAGS_OPTIMIZE to use -O2 instead of -Oti. Noted TCL_LIB_VERSIONS_OK=nodots for Windows builds. A few changes to support itcl (and perhaps others): Added support for making your own stub libraries to SC_MAKE_LIB. New SC_PATH_CONFIG and SC_LOAD_CONFIG that take a package name arg and find that ${pkg}Config.sh file. itk uses this for itcl. 2002-03-27 Jeff Hobbs * tcl.m4: made SC_LOAD_TKCONFIG recognize when working with a Tk build dir setup. Added EXTRA_CFLAGS and SHLIB_LD_LIBS substs to SC_CONFIG_CFLAGS. Added XLIBSW onto LIBS when it is defined. Remove TCL_LIBS from MAKE_LIB and correctly use SHLIB_LD_LIBS instead to not rely as much on tclConfig.sh cached info. Add TK_BIN_DIR to paths to find wish in SC_PROG_WISH. These move towards making TEA much more independent of *Config.sh. 2002-03-19 Jeff Hobbs * tcl.m4: corrected forgotten (UN)SHARED_LIB_SUFFIX and SHLIB_SUFFIX defines for Win. (SC_PATH_X): made this only do the check on unix platforms. 2002-03-12 Jeff Hobbs * README.txt: updated to reflect fewer files 2002-03-06 Jeff Hobbs * config.guess (removed): * config.sub (removed): removed unnecessary files * installFile.tcl (removed): * mkinstalldirs (removed): these aren't really necessary for making TEA work * tcl.m4 (SC_PUBLIC_TCL_HEADERS, SC_PUBLIC_TK_HEADERS): don't check /usr(/local)/include for includes on Windows when not using gcc 2002-03-05 Jeff Hobbs * tcl.m4: added warnings on Windows, removed RELPATH define and added TCL_LIBS to MAKE_LIB macro. This import represents 2.0.0, or a new start at attempting to make TEA much easier for C extension developers. **** moved from tclpro project to core tcl project, **** **** renamed to 'tclconfig' **** 2001-03-15 Karl Lehenbauer * installFile.tcl: Added updating of the modification time of the target file whether we overwrote it or decided that it hadn't changed. This was necessary for us to be able to determine whether or not a module install touched the file. 2001-03-08 Karl Lehenbauer * installFile.tcl: Added support for converting new-style (1.1+) Cygnus drive paths to Tcl-style. 2001-01-15 * tcl.m4: Added FreeBSD clause. 2001-01-03 * tcl.m4: Fixed typo in SC_LIB_SPEC where it is checking for exec-prefix. 2000-12-01 * tcl.m4: Concatenated most of the Ajuba acsite.m4 file so we don't need to modify the autoconf installation. * config.guess: * config.sub: * installFile.tcl: Added files from the itcl config subdirectory, which should go away. 2000-7-29 * Fixed the use of TCL_SRC_DIR and TK_SRC_DIR within TCL_PRIVATE_INCLUDES and TK_PRIVATE_INCLUDES to match their recent change from $(srcdir) to $(srcdir)/.. tksvg-0.14/tclconfig/README.txt000066400000000000000000000015041452770645000162540ustar00rootroot00000000000000These files comprise the basic building blocks for a Tcl Extension Architecture (TEA) extension.
