Thanks for the research. I can see why you did it this way, because of the way CFLAGS changes through the configure script. We could also do: 's/-O2/& -march=i486/' The difference between that and the one you gave being that this would also hit CXXFLAGS which by default uses the same flags as CFLAGS in the configure script. It doesn't seem necessary to use -march with CXXFLAGS to get glibc to build, but I'm curious as to the result. Is anyone already familiar with Glibc's use of CXXFLAGS? -- JH -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
