Hello, As per https://bugs.launchpad.net/ubuntu/+source/gcc-5/+bug/1522410/comments/9 the power9 cpu option is added in the gcc-5 (5.3.1-6ubuntu1) package.
Could you please upgrade to 5.3.1-6ubuntu1 first, and verify that that's the version installed on disk, before validating this feature? $ dpkg-query -W gcc-5 gcc-5 5.3.1-6ubuntu1 Regards, Dimitri. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1522410 Title: [Ubuntu 16.04] Enable P9 toolchain To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gcc-5/+bug/1522410/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
