mistranslation: 0.814 graphic: 0.789 device: 0.705 instruction: 0.673 semantic: 0.624 other: 0.473 network: 0.414 vnc: 0.284 socket: 0.272 boot: 0.194 assembly: 0.061 KVM: 0.019 v2.8.0 won't compile if g++ compiler doesn't understand "-fstack-protector-strong" For example, Ubuntu Trusty (LTS 14.04) uses g++ v4.8.5. Compilation fails with a syntax error saying that the ""-fstack-protector-strong" option in g++ is unrecognized. Instead, under Ubuntu Xenial (LTS 16.04), the g++ compiler is v5.4.0 and the compilation goes on smoothly. Could you provide the command you've used? I tried `CC=gcc-4.8 ./configure --enable-stack-protector && make` in Ubuntu 14.04 and qemu v2.8.0. It didn't set `-fstack-protector-strong` flag, only `-fstack-protector-all`. Which version of gcc (i.e. normal C-compiler, not g++) did you use here? Can you still reproduce this issue with the latest release of QEMU?
