"-g -O2" is simply a default if CFLAGS is not already set. It is by no means set in stone, and in fact any package that insists on a particular setting of CFLAGS is broken since this is meant to be a user-supplied variable. You are expected to set CFLAGS when configuring if you want something else. For example if you have a package and you want to build it both optimized without debug information as well as a debug build: $ mkdir build-release && cd build-release $ CFLAGS="-g0 -O2" ../configure --prefix=/opt/foobar && make $ cd .. $ mkdir build-debug && cd build-debug $ CFLAGS="-g -O0" ../configure --prefix=/opt/foobar && make Brian _______________________________________________ Autoconf mailing list Autoconf@gnu.org http://lists.gnu.org/mailman/listinfo/autoconf
