--- Comment #6 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Marek Polacek <mpola...@gcc.gnu.org>: https://gcc.gnu.org/g:e0eca4a55bd14d506708fb0396b31e7f7383160c commit r14-6220-ge0eca4a55bd14d506708fb0396b31e7f7383160c Author: Marek Polacek <pola...@redhat.com> Date: Tue Dec 5 13:39:49 2023 -0500 build: unbreak bootstrap on uclinux targets [PR112762] Currently, cross-compiling with --target=c6x-uclinux (and several other) fails due to: ../../src/gcc/config/linux.h:221:45: error: 'linux_fortify_source_default_level' was not declared in this scope #define TARGET_FORTIFY_SOURCE_DEFAULT_LEVEL linux_fortify_source_default_level In the PR Andrew mentions that another fix would be in config.gcc, but really, here I meant to use the target hook for glibc only, not uclibc. This trivial patch fixes the build problem. It means that -fhardened with uclibc will use -D_FORTIFY_SOURCE=2 and not =3. PR target/112762 gcc/ChangeLog: * config/linux.h: Redefine TARGET_FORTIFY_SOURCE_DEFAULT_LEVEL for glibc only.
