Public bug reported: While this might be a kernel build problem (see LP: #1939308) I wanted to raise the issue against the toolchain just so we can make sure it's *not* a toolchain bug. Basically the following behavior changed from gcc 10:
$ arm-linux-gnueabihf-gcc-10 -march=armv7-a -c -x c /dev/null ; echo $? 0 $ arm-linux-gnueabihf-gcc-11 -march=armv7-a -c -x c /dev/null ; echo $? cc1: error: ‘-mfloat-abi=hard’: selected architecture lacks an FPU 1 Presumably the GCC 11 hard-float compiler now enforces the default config --with-float=hard? ** Affects: gcc-defaults (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1939379 Title: ARM kernel builds fail with GCC 11 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gcc-defaults/+bug/1939379/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
