dnl QTHREADS_CONFIGURE configures the QuickThreads package. The QT

dnl sources should be in $srcdir/qt. If configuration succeeds, this
|
|
dnl macro creates the appropriate symlinks in the qt object directory,
|
|
dnl and sets the following variables, used in building libqthreads.a:
|
|
dnl QTHREAD_LTLIBS --- set to libqthreads.la if configuration
|
|
dnl succeeds, or the empty string if configuration fails.
|
|
dnl qtmd_h, qtmds_s, qtmdc_c, qtdmdb_s --- the names of the machine-
|
|
dnl dependent source files.
|
|
dnl qthread_asflags --- flags to pass to the compiler when processing
|
|
dnl assembly-language files.
|
|
dnl
|
|
dnl It also sets the following variables, which describe how clients
|
|
dnl can link against libqthreads.a:
|
|
dnl THREAD_PACKAGE --- set to "QT" if configuration succeeds, or
|
|
dnl the empty string if configuration fails.
|
|
dnl THREAD_CPPFLAGS --- set to `-I' flags for thread header files
|
|
dnl THREAD_LIBS_LOCAL --- linker options for use in this source tree
|
|
dnl THREAD_LIBS_INSTALLED --- linker options for use after this package
|
|
dnl is installed
|
|
dnl It would be nice if all thread configuration packages for Guile
|
|
dnl followed the same conventions.
|
|
dnl
|
|
dnl All of the above variables will be substituted into Makefiles in
|
|
dnl the usual autoconf fashion.
|
|
dnl
|
|
dnl We distinguish between THREAD_LIBS_LOCAL and
|
|
dnl THREAD_LIBS_INSTALLED because the thread library might be in
|
|
dnl this tree, and be built using libtool. This means that:
|
|
dnl 1) when building other executables in this tree, one must
|
|
dnl pass the relative path to the ../libfoo.la file, but
|
|
dnl 2) once the whole package has been installed, users should
|
|
dnl link using -lfoo.
|
|
dnl Normally, we only care about the first case, but since the
|
|
dnl guile-config script needs to give users all the flags they need
|
|
dnl to link programs against guile, the GUILE_WITH_THREADS macro
|
|
dnl needs to supply the second piece of information as well.
|
|
dnl
|
|
dnl This whole thing is a little confused about what ought to be
|
|
dnl done in the top-level configure script, and what ought to be
|
|
dnl taken care of in the subdirectory. For example, qtmds_s and
|
|
dnl friends really ought not to be even mentioned in the top-level
|
|
dnl configure script, but here they are.
