Arg, no. -Werror is very useful for development and I'm sure that code quality increases because of it, but it should never be enabled by default for releases. I think about 80% of the bugs we've had filed so far for packages failing to build against 4.8 are due to -Werror. Also, several distros patch gcc to enable additional warnings by default (eg. Debian, Ubuntu, and Gentoo enable -Wformat=security) that upstream may not see or be interested in. It's a big enough headache that we had to ban use of -Werror from our tree (instead we flag important warnings and output them at the end of the build). -- Ryan Hill psn: dirtyepic_sk gcc-porting/toolchain/wxwidgets @ gentoo.org 47C3 6D62 4864 0E49 8E9E 7F92 ED38 BD49 957A 8463
