Fortunately, the failure mode for non-existing directories is non-fatal (skipped with 'subdirectory [...] not present' diagnostic); with my original "Enable top-level recursive 'autoreconf'" (also re-attached) applied to Binutils/GDB Git master branch, we get: $ PATH=[...] autoreconf -v autoreconf: Entering directory `.' autoreconf: configure.ac: not using Gettext autoreconf: running: aclocal autoreconf: configure.ac: tracing autoreconf: configure.ac: subdirectory c++tools not present autoreconf: configure.ac: subdirectory fixincludes not present autoreconf: configure.ac: subdirectory gcc not present autoreconf: configure.ac: subdirectory gcc/m2 not present autoreconf: configure.ac: subdirectory gnattools not present autoreconf: configure.ac: subdirectory gotools not present autoreconf: configure.ac: adding subdirectory intl to autoreconf autoreconf: Entering directory `intl' [...] autoreconf: Leaving directory `intl' autoreconf: configure.ac: subdirectory libada not present autoreconf: configure.ac: subdirectory libatomic not present autoreconf: configure.ac: adding subdirectory libbacktrace to autoreconf autoreconf: Entering directory `libbacktrace' [...] So we could (a) simply list *all* directories in the shared top-level 'configure.ac', or (b) configure GCC vs. other projrcts via a non-shared file ('m4_include([config/AC_CONFIG_SUBDIRS.m4])' or similar -- is there an established procedure for non-shared top-level files)?

Not sure if that counts as "shared", but I regularly drop in* newlib to build simulator targets (*-elf, *-newabi). That's git://sourceware.org/git/newlib-cygwin.git but I extract tarballs for the merging. "Drop in" is actually the other way round, starting with a newlib tarball, so gcc files overwrite newlib ones. (FWIW, I never drop in binutils like that; they're better built separately.

Interesting idea! It is a little hackish, in that it seems to exploit an implementation detail in AC_CONFIG_SUBDIRS rather than a documented feature. I like it! The autoconf documentation suggests that optional directories can be tested for: if test -d "$srcdir/foo"; then AC_CONFIG_SUBDIRS([foo]) fi We could use a macro that takes a list and iterates over the list (untested): dnl Handle a list of optional subdirs. dnl After AC_OUTPUT, affects autoreconf runs, but not configure runs. AC_DEFUN([AC_CONFIG_SUBDIRS_OPT], [ m4_foreach_w([dir], [$1], [ if test -d "$srcdir/dir"; then AC_CONFIG_SUBDIRS(dir) fi ]) ]) Thanks, -- Alexandre Oliva, happy hacker https://FSFLA.org/blogs/lxo/ Free Software Activist GNU Toolchain Engineer More tolerance and less prejudice are key for inclusion and diversity Excluding neuro-others for not behaving ""normal"" is *not* inclusive ^ permalink raw reply [flat|nested] 6+ messages in thread
