1 | dnl Autoconf macros for configuring the QuickThreads package |
2 | ||
3 | dnl QTHREADS_CONFIGURE configures the QuickThreads package. The QT | |
4 | dnl sources should be in $srcdir/qt. If configuration succeeds, this | |
5 | dnl macro creates the appropriate symlinks in the qt object directory, | |
6 | dnl and sets the following variables, used in building libqthreads.a: | |
7 | dnl QTHREAD_LTLIBS --- set to libqthreads.la if configuration | |
8 | dnl succeeds, or the empty string if configuration fails. | |
47521807 JB |
9 | dnl qtmd_h, qtmds_s, qtmdc_c, qtdmdb_s --- the names of the machine- |
10 | dnl dependent source files. | |
11 | dnl qthread_asflags --- flags to pass to the compiler when processing | |
12 | dnl assembly-language files. | |
539c89a1 JB |
13 | dnl |
14 | dnl It also sets the following variables, which describe how clients | |
15 | dnl can link against libqthreads.a: | |
16 | dnl THREAD_PACKAGE --- set to "QT" if configuration succeeds, or | |
17 | dnl the empty string if configuration fails. | |
18 | dnl THREAD_CPPFLAGS --- set to `-I' flags for thread header files | |
19 | dnl THREAD_LIBS_LOCAL --- linker options for use in this source tree | |
20 | dnl THREAD_LIBS_INSTALLED --- linker options for use after this package | |
21 | dnl is installed | |
22 | dnl It would be nice if all thread configuration packages for Guile | |
23 | dnl followed the same conventions. | |
24 | dnl | |
25 | dnl All of the above variables will be substituted into Makefiles in | |
26 | dnl the usual autoconf fashion. | |
27 | dnl | |
28 | dnl We distinguish between THREAD_LIBS_LOCAL and | |
29 | dnl THREAD_LIBS_INSTALLED because the thread library might be in | |
30 | dnl this tree, and be built using libtool. This means that: | |
31 | dnl 1) when building other executables in this tree, one must | |
32 | dnl pass the relative path to the ../libfoo.la file, but | |
33 | dnl 2) once the whole package has been installed, users should | |
34 | dnl link using -lfoo. | |
35 | dnl Normally, we only care about the first case, but since the | |
bcc695e3 | 36 | dnl guile-config script needs to give users all the flags they need |
539c89a1 JB |
37 | dnl to link programs against guile, the GUILE_WITH_THREADS macro |
38 | dnl needs to supply the second piece of information as well. | |
39 | dnl | |
40 | dnl This whole thing is a little confused about what ought to be | |
41 | dnl done in the top-level configure script, and what ought to be | |
47521807 | 42 | dnl taken care of in the subdirectory. For example, qtmds_s and |
539c89a1 JB |
43 | dnl friends really ought not to be even mentioned in the top-level |
44 | dnl configure script, but here they are. | |
