But only if they are both in libs or both in tests. If you have strerror in libs and strerror_r in tests, and both try to do AC_LIBOBJ, then you get into the funky situation where strerror-overrided.c is not in the tests directory and the build fails. Compare to the problem we were solving earlier with fclose vs. fflush being in separate directories, and the AC_LIBOBJ([fflush]) giving us grief. Which is why we need a separate module as prereq for both strerror and strerror_r-posix, so that the AC_LIBOBJ only occurs in one directory corresponding to where strerror-override.c is placed. -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
