For toolchain it's fine.
We can alter the spec too, forcing gcc to defaut for -fno-stack-protector. > --disable-libssp can be used again in the chroot when building gcc. > Everything in this library is included in Glibc-2.8, and libssp is just a > waste of space. Ok, but if you want this in your final system? I've been use stack-protection for a year with gcc-4.1.x and glibc-2.5.x in production and don't want to loose this now!!! :-( (note: glibc *is not* compiled with ssp in my hosts, but any other package is) I think forcing a -fno-stack-protector to glibc is better than send libssp entirely to oblivion. > > robert thx -- Valter Douglas Lisbôa Jr. Sócio-Diretor Trenix - IT Solutions "Nossas Idéias, suas Soluções!" www.trenix.com.br [EMAIL PROTECTED] -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
