Are you saying that --enable-thread-safety isn't setting PTHREAD_CFLAGS
and PTHREAD_LIBS in Makefile.global properly? If so, please check out
config.log to see why it isn't trying those flags? What settings to you
have for those anyway?
We have this in config/acx_pthread.m4 which modifies the flags tried on
Solaris:
case "${host_cpu}-${host_os}" in
*solaris*)
# On Solaris (at least, for some versions), libc contains stubbed
# (non-functional) versions of the pthreads routines, so link-based
# tests will erroneously succeed. (We need to link with -pthread or
# -lpthread.) (The stubs are missing pthread_cleanup_push, or rather
# a function called by this macro, so we could check for that, but
# who knows whether they'll stub that too in a future libc.) So,
# we'll just look for -pthreads and -lpthread first:
acx_pthread_flags="-pthread -pthreads pthread -mt $acx_pthread_flags"
;;
esac
Is this incorrect? Feel free to wack around configure (which is built
from config/acx_pthread.m4) and let us know what works.
