(SC_ENABLE_LANGINFO, SC_TIME_HANDLER): add/fix caching, fix obsolete autoconf macros. Sync with tk/unix/tcl.m4, sync whitespace with HEAD. * unix/configure.in: fix obsolete autoconf macros, sync gratuitous formatting/ordering differences with tk/unix/configure.in. * unix/Makefile.in: add CFLAGS to tclsh/tcltest link to make executable linking the same as during configure (needed to avoid loosing any linker relevant flags in CFLAGS, in particular flags that can't be in LDFLAGS). Avoid concurrent linking of tclsh and compiling of tclTestInit.o or xtTestInit.o during parallel make. (checkstubs, checkdoc, checkexports): dependency and Darwin fixes * unix/tclLoadDyld.c (TclpDlopen): use NSADDIMAGE_OPTION_WITH_SEARCHING on second NSAddImage only. [Bug 1204237] (TclGuessPackageName): should not be MODULE_SCOPE. (TclpLoadMemory): ppc64 and endian (i386) fixes, add support for loading universal (fat) bundles from memory. * unix/tclUnixPort.h: * unix/tclUnixFCmd.c: add support for new Tiger copyfile() API to enable copying of xattrs & ACLs by [file copy]. * generic/tcl.h: add Darwin specifc configure overrides for TCL_WIDE defines to support fat compiles of ppc and ppc64 at the same time, (replaces Darwin CVS fix by emoy, rdar://3693001). add/correct location of version numbers in macosx files. * generic/tclInt.h: clarify fat compile comment. * unix/tclUnixPort.h: add Darwin specifc configure overrides to support fat compiles, where configure runs only once for multiple architectures (replaces Darwin CVS fix by emoy, rdar://3693001). * macosx/tclMacOSXBundle.c: * macosx/tclMacOSXNotify.c: * unix/tclUnixNotfy.c: * unix/tclUnixPort.h: fix #include order to support compile time override of HAVE_COREFOUNDATION in tclUnixPort.h when building for ppc64 * macosx/Tcl.pbproj/default.pbxuser (new file): * macosx/Tcl.pbproj/jingham.pbxuser: * macosx/Tcl.pbproj/project.pbxproj: sync with HEAD. * macosx/README: clarification/cleanup, sync with HEAD, document universal (fat) builds via CFLAGS (i.e. all of ppc ppc64 i386 at once). * macosx/Makefile: add support for reusing configure cache, build target fixes, remove GENERIC_FLAGS override now handled by tcl.m4. * generic/tclIOUtil.c: * generic/tclRegexp.c: * generic/tclVar.c: declare globals used only in own file as static (sync with HEAD). * generic/rege_dfa.c (getvacant): * generic/regexec.c (cfind): * generic/tclCompExpr.c (CompileSubExpr): * unix/tclUnixChan.c (TclUnixWaitForFile): initialise variables to silence gcc 4 warnings. * generic/regguts.h: only #define NDEBUG if not already #defined. * macosx/tclMacOSXNotify.c: sync whitespace & comments with HEAD * unix/configure: regen.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * unix/tclUnixInit.c: * unix/tcl.m4 (Darwin): made use of CoreFoundation API configurable and added test of CoreFoundation availablility to allow building on ppc64, replaced HAVE_CFBUNDLE by HAVE_COREFOUNDATION; test for availability of Tiger or later OSSpinLockLock API. * unix/tclUnixNotfy.c: * unix/Makefile.in: * macosx/tclMacOSXNotify.c (new file): when CoreFoundation is available, use new CFRunLoop based notifier: allows easy integration with other event loops on Mac OS X, in particular the TkAqua Carbon event loop is now integrated via a standard tcl event source (instead of TkAqua upon loading having to finalize the exsting notifier and replace it with its custom version). [Patch 1202052] * tests/unixNotfy.test: don't run unthreaded tests on Darwin since notifier may be using threads even in unthreaded core. * unix/tclUnixPort.h: * unix/tcl.m4 (Darwin): test for thread-unsafe realpath durning configure, as Darwin 7 and later realpath is threadsafe. * macosx/tclMacOSXBundle.c: * unix/tclLoadDyld.c: * unix/tclUnixInit.c: fixed gcc 4.0 warnings. * unix/configure: autoconf-2.13

(SC_MISSING_POSIX_HEADERS): added caching of dirent.h check. (SC_TCL_64BIT_FLAGS): fixed 'checking for off64_t' message output. * unix/configure: autoconf-2.13

(SC_ENABLE_THREADS): Set m4 to force threaded build when built against a threaded Tcl core. Reorder configure.in for better 64-bit build configuration, replacing EXTRA_CFLAGS with CFLAGS.

| | | | | | | | | | | | | | | | | | | | | | | | | | | to be purely make driven; in order to become independent of Apple's closed-source IDE and build tool. The changes are intended to be transparent to the Makefile user, all existing make targets and cmd line variable overrides should continue to work. Changed build to only include tcl specific html help in Tcl.framework, the tk specific html help is now included in Tk.framework. * macosx/Tcl.pbproj/project.pbxproj: * macosx/Tcl.pbproj/jingham.pbxuser: Changed to purely call through to the make driven buildsystem; Tcl.framework is no longer assembled by ProjectBuilder. Set default SYMROOT in target options to simplify setting up PB (manually setting common build folder for tcl & tk no longer needed). * tools/tcltk-man2html.tcl: Added options to allow building only the tcl or tk html help files; the default behaviour with none of the new options is to build both, as before. * unix/Makefile.in: Added targets for building only the tcl or tk help. * macosx/README (new): Tcl specific excerpts of tk/macosx/README. * generic/tcl.h: Updated reminder comment about editing macosx/Tcl.pbproj/project.pbxproj when version number changes.

Incorporate TCL_DBGX into the Tcl pipe dll name. This fixes a really mysterious error that would show up when exec'ing a 16 bit application under Win95 or Win98 when Tcl was compiled with symbols. The error seemed to indicate that the executable could not be found, but it was actually the Tcl pipe dll that could not be found.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * generic/tcl.decls: added new macosx specific entry to stubs table. * tools/genStubs.tcl: added generation of platform guards for macosx. This is a little more complex than it seems, because MacOS X IS "unix" plus a little bit, for the purposes of Tcl. BUT unfortunately, Tk uses "unix" to mean X11. So added platform keys for macosx (the little added to "unix"), "aqua" and "x11" to distinguish these for Tk. * generic/tcl.h: added a #ifnded RESOURCE_INCLUDED so that tcl.h can be passed to the resource compiler. * generic/tcl.h: * generic/tclNotify.c: added a few Notifier procs, to be able to modify more bits of the Tcl notifier dynamically. Required to get Mac OS X Tk to live on top of the Tcl Unix threaded notifier. Changes the size of the Tcl_NotifierProcs structure, but doesn't move any elements around. * unix/tclUnixNotfy.c: moved the call to Tcl_ConditionNotify till AFTER we are done mucking with the pointer swap. Fixes cases where the thread waiting on the condition wakes & accesses the waitingListPtr before it gets reset, causing a hang. * library/auto.tcl (tcl_findLibrary): added checking the directories in the tcl_pkgPath for library files on macosx to enable support of the standard Mac OSX library locations * unix/Makefile.in: * unix/configure.in: * unix/tcl.m4: added MAC_OSX_DIR. Added PLAT_OBJS to the OBJS: there are some MacOS X specific files now for Tcl, and when I get he resource & applescript stuff ported over, and restore support for FindFiles, etc, there will be a few more. Added LD_LIBRARY_PATH_VAR configure variable to avoid having to set all possible LD_LIBRARY_PATH analogues on all platforms. LD_LIBRARY_PATH_VAR is "LD_LIBRARY_PATH" by default, "LIBPATH" on AIX, "SHLIB_PATH" on HPUX and "DYLD_LIBRARY_PATH" on Mac OSX. Added configure option to package Tcl as a framework on Mac OSX. * macosx/tclMacOSXBundle.c (new): support for finding Tcl extension packaged as 'bundles' in the standard Mac OSX library locations. * unix/tclUnixInit.c: added support for findig the tcl script library inside Tcl packaged as a framework on Mac OSX. * macosx/Tcl.pbproj/jingham.pbxuser (new): * macosx/Tcl.pbproj/project.pbxproj (new): project for Apple's ProjectBuilder IDE. * macosx/Makefile (new): simple makefile for building the project from the command line via the ProjectBuilder tool 'pbxbuild'. * unix/configure: * generic/tclStubInit.c: * generic/tclPlatDecls.h: regen
* * win/Makefile.in (CFLAGS):andreas_kupries2002-08-221-2/+2

Allows a user of configure to (de)activate memory validation and debugging (TCL_MEM_DEBUG). No need to modify the makefile anymore.

Move subst of a number of variables into tcl.m4 where they are defined. * unix/tcl.m4 (SC_ENABLE_SYMBOLS, SC_CONFIG_CFLAGS): Subst vars where they are defined. Add MAKE_LIB, MAKE_STUB_LIB, INSTALL_LIB, and INSTALL_STUB_LIB rules to deal with the ugly details of running ranlib on static libs at build and install time. Replace TCL_SHLIB_LD_EXTRAS with SHLIB_LD_FLAGS and use it when building a shared library. * unix/tclConfig.sh.in: Add TCL_CC_SEARCH_FLAGS.
