From: Romain Naour Date: Mon, 27 Jul 2020 09:29:48 +0000 (+0200) Subject: package/gcc: disable libsanitizer with gcc 7.5 and glibc 2.31 toolchain X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3df30211200da12bb4d4efd84ab79e709751e77a;p=buildroot.git package/gcc: disable libsanitizer with gcc 7.5 and glibc 2.31 toolchain libsanitizer in gcc 7.x fails to build with glibc 2.31. Fixing it would require backporting an upstream commit: https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=4abc46b51af5751d657764d0c44b8a4aeed06302 However, the backport is not trivial, as there are a lot of conflicts. Disable libsanitizer since the gcc 7.5 branch is now closed (unmaintained) and it's not a trivial merge. Signed-off-by: Romain Naour Signed-off-by: Yann E.
