If you post config.guess patches to the correct upstream location (config-patches AT gnu DOT org), then the next release of m4 will automatically include it. Meanwhile, your remaining bugs both relate to code that m4 borrows from gnulib, so fixing it in gnulib will aid in porting other GNU projects to AIX. > I also have > changed m4/posix_spawn.m4 so that > "gl_cv_func_posix_spawn_works="guessing yes";;" is set. According to my > tests the old POSIX spawn problem (which was present in early AIX > 5.3/6.1 versions) is gone. That would actually be a problem to report to bug-gnulib, but why is configure rejecting the implementation if you don't seed the cache? > > The make run shown one problem: > > source='execute.c' object='execute.o' libtool=no DEPDIR=.deps > depmode=aix /bin/sh ../build-aux/ > depcomp cc -qlanglvl=extc89 -qlanglvl=extc99 -I. -g -c execute.c > "./spawn.h", line 141.10: 1506-236 (W) Macro name POSIX_SPAWN_RESETIDS > has been redefined. Hmm - even though you requested the posix_spawn override, you either did not request enough other overrides, so your incomplete cache seeding is causing interference with the rest of things gnulib is trying to guarantee, or there's still a bug in AIX posix_spawn that needs working around, but in a way that gnulib is not yet prepared for. > src/spawn.h > > # define POSIX_SPAWN_RESETIDS 0x01 > # define POSIX_SPAWN_SETPGROUP 0x02 > # define POSIX_SPAWN_SETSIGDEF 0x04 > # define POSIX_SPAWN_SETSIGMASK 0x08 > # define POSIX_SPAWN_SETSCHEDPARAM 0x10 > # define POSIX_SPAWN_SETSCHEDULER 0x20 > > AIX 7.1 defines spawn.h: > > #define POSIX_SPAWN_SETPGROUP 0x1 > #define POSIX_SPAWN_SETSIGMASK 0x2 > #define POSIX_SPAWN_SETSIGDEF 0x4 > #define POSIX_SPAWN_SETSCHEDULER 0x8 > #define POSIX_SPAWN_SETSCHEDPARAM 0x10 > #define POSIX_SPAWN_RESETIDS 0x20 > #define POSIX_SPAWN_FORK_HANDLERS 0x1000 > > > > The make check run yields one problem: > > /bin/sh: 5505092 IOT/Abort trap(coredump) > FAIL: test-strtod > > Is this a know problem ? Did configure try to replace AIX' strtod? Which line is it failing on? Chances are there's a bug in AIX' strtod with C99 compliance that is not yet being detected at configure time, but which we can work around if we know what the bug is. Can you also post the relevant config.log bits for the posix_spawn- and strtod-related probes? -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
