This is required when building gcc because gcc itself does not include a libc and it requires the headers when building libgcc and the other target libraries like libstdc++. You normally point gcc to them using --with-headers or --with-sysroot et cetera. The easiest route is to get the C library headers from an existing distro, in particular the same one (or one very similar to) that you intend to eventually run your program on. I.e. get them from the libc-devel deb/rpm package. It is also possible if there is no existing system to bootstrap gcc and the libc together, but it's a lot more work. You end up building a stripped down C-only gcc, then using that to configure parts of the libc, then using those headers to rebuild a full gcc, then using that to actually build libc. This is the method that the crosstool script uses and if you want to go that route it's much easier just to run crosstool and let it do everything. Brian
