Autoconf-generated configure scripts do _NOT_ support -Werror; it is too problematic to ever guarantee that all possible warnings from all possible gcc versions will always be silenced. It is permissible to configure without -Werror, and add it later via 'make CFLAGS="-Werror ..."', once configure has found correct results. But by injecting -Werror too soon into the process, you've made configure guess a wrong result: > cc1: warnings being treated as errors > conftest.c: In function 'main': > conftest.c:69:10: error: 't' is used uninitialized in this function > conftest.c:85:23: error: 'b' may be used uninitialized in this function ... > configure:12809: result: no with disastrous consequences on the rest of the project compilation. -- Eric Blake eblake@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
