../gcc-4.3-work/configure --prefix=/opt/gcc/gcc4.3w --mandir=/opt/gcc/gcc4.3w/share/man --infodir=/opt/gcc/gcc4.3w/share/info --build=i686-apple-darwin9 --enable-languages=c,c++,fortran,objc,obj-c++,java --with-gmp=/sw --with-libiconv-prefix=/usr --with-system-zlib --x-includes=/usr/X11R6/include --x-libraries=/usr/X11R6/lib --enable-maintainer-mode --disable-werror I still get the same failure: cc1plus: warnings being treated as errors /opt/gcc/gcc-4.3-work/libstdc++-v3/../gcc/unwind-pe.h:74: error: 'unsigned int size_of_encoded_value(unsigned char)' defined but not used According the manual: --enable-werror --disable-werror --enable-werror=yes --enable-werror=no When you specify this option, it controls whether certain files in the compiler are built with -Werror in bootstrap stage2 and later. If you don't specify it, -Werror is turned on for the main development trunk. However it defaults to off for release branches and final releases. The specific files which get -Werror are controlled by the Makefiles. Why do I have '-Werror' while building libstdc++-v3? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34780
