Reading a bit further, misalignment between older and current gcc versions gets a mention: https://sourceware.org/ml/libc-alpha/2013-08/msg00291.html > In the glibc build procedures, a simple sed to the glibc code seems to > fix the problem: > > sed -i -e 's/static __m128i/inline &/' sysdeps/x86_64/multiarch/strstr.c > > I am proposing that we add this to both Chapter 5 and Chapter 6 of LFS. > I'm not sure if we need to do an -rc2 or not. > > -- Bruce Does that also alter x86_64 builds, or are you going to wrap it ?
