Anyway, if the book says that CFLAGS > should NOT be set, that covers it. Section 5.2 says that CFLAGS should not be set when building cross tools. The book doesn't mention CFLAGS when building the temporary or final systems. Now that I think of it, it's probably not worth setting it during the temporary stage since this stage will be thrown away. I'm not interested in having static libraries on my system, so I guess -fPIC isn't needed. >> The headers problem was caused by experimenting with config.site.

It helps me understand some of the less obvious reasons LFS does certain things. I didn't use config.site for the cross toolchain, but I am for the temporary stage. I experimented with --with-sysroot earlier. It eliminates the need for a few patches for some reason, but then gcc stupidly insists that headers and libraries must be in usr if it is passed --with-sysroot. I don't really like the idea of putting glibc into usr without testing it first, simply to satisfy gcc. CLFS-2 does this and I am curious why. CLFS-2 is still under development, tho, so maybe it won't stay in there? _______________________________________________ Clfs-support mailing list [email protected] http://lists.cross-lfs.org/cgi-bin/mailman/listinfo/clfs-support
