654 dnl QTHREADS_CONFIGURE configures the QuickThreads package. The QT
655 dnl sources should be in $srcdir/qt. If configuration succeeds, this
656 dnl macro creates the appropriate symlinks in the qt object directory,
657 dnl and sets the following variables, used in building libqthreads.a:
658 dnl QTHREAD_LTLIBS --- set to libqthreads.la if configuration
659 dnl succeeds, or the empty string if configuration fails.
660 dnl qtmd_h, qtmds_s, qtmdc_c, qtdmdb_s --- the names of the machine-
661 dnl dependent source files.
662 dnl qthread_asflags --- flags to pass to the compiler when processing
663 dnl assembly-language files.
665 dnl It also sets the following variables, which describe how clients
666 dnl can link against libqthreads.a:
667 dnl THREAD_PACKAGE --- set to "QT" if configuration succeeds, or
668 dnl the empty string if configuration fails.
669 dnl THREAD_CPPFLAGS --- set to `-I' flags for thread header files
670 dnl THREAD_LIBS_LOCAL --- linker options for use in this source tree
671 dnl THREAD_LIBS_INSTALLED --- linker options for use after this package
673 dnl It would be nice if all thread configuration packages for Guile
674 dnl followed the same conventions.
676 dnl All of the above variables will be substituted into Makefiles in
677 dnl the usual autoconf fashion.
679 dnl We distinguish between THREAD_LIBS_LOCAL and
680 dnl THREAD_LIBS_INSTALLED because the thread library might be in
681 dnl this tree, and be built using libtool. This means that:
682 dnl 1) when building other executables in this tree, one must
683 dnl pass the relative path to the ../libfoo.la file, but
684 dnl 2) once the whole package has been installed, users should
685 dnl link using -lfoo.
686 dnl Normally, we only care about the first case, but since the
687 dnl guile-config script needs to give users all the flags they need
688 dnl to link programs against guile, the GUILE_WITH_THREADS macro
689 dnl needs to supply the second piece of information as well.
