157 | dnl QTHREADS_CONFIGURE configures the QuickThreads package. The QT |
158 | dnl sources should be in $srcdir/qt. If configuration succeeds, this | |
159 | dnl macro creates the appropriate symlinks in the qt object directory, | |
160 | dnl and sets the following variables, used in building libqthreads.a: | |
161 | dnl QTHREAD_LTLIBS --- set to libqthreads.la if configuration | |
162 | dnl succeeds, or the empty string if configuration fails. | |
163 | dnl qtmd_h, qtmds_s, qtmdc_c, qtdmdb_s --- the names of the machine- | |
164 | dnl dependent source files. | |
165 | dnl qthread_asflags --- flags to pass to the compiler when processing | |
166 | dnl assembly-language files. | |
167 | dnl | |
168 | dnl It also sets the following variables, which describe how clients | |
169 | dnl can link against libqthreads.a: | |
170 | dnl THREAD_PACKAGE --- set to "QT" if configuration succeeds, or | |
171 | dnl the empty string if configuration fails. | |
172 | dnl THREAD_CPPFLAGS --- set to `-I' flags for thread header files | |
173 | dnl THREAD_LIBS_LOCAL --- linker options for use in this source tree | |
174 | dnl THREAD_LIBS_INSTALLED --- linker options for use after this package | |
175 | dnl is installed | |
176 | dnl It would be nice if all thread configuration packages for Guile | |
177 | dnl followed the same conventions. | |
178 | dnl | |
179 | dnl All of the above variables will be substituted into Makefiles in | |
180 | dnl the usual autoconf fashion. | |
181 | dnl | |
182 | dnl We distinguish between THREAD_LIBS_LOCAL and | |
183 | dnl THREAD_LIBS_INSTALLED because the thread library might be in | |
184 | dnl this tree, and be built using libtool. This means that: | |
185 | dnl 1) when building other executables in this tree, one must | |
186 | dnl pass the relative path to the ../libfoo.la file, but | |
187 | dnl 2) once the whole package has been installed, users should | |
188 | dnl link using -lfoo. | |
189 | dnl Normally, we only care about the first case, but since the | |
190 | dnl guile-config script needs to give users all the flags they need | |
191 | dnl to link programs against guile, the GUILE_WITH_THREADS macro | |
192 | dnl needs to supply the second piece of information as well. | |
193 | dnl | |
194 | dnl This whole thing is a little confused about what ought to be | |
195 | dnl done in the top-level configure script, and what ought to be | |
196 | dnl taken care of in the subdirectory. For example, qtmds_s and | |
197 | dnl friends really ought not to be even mentioned in the top-level | |
198 | dnl configure script, but here they are. | |
