I meet many problems indeed. With default the GCC search the /usr/lib directory inside sysroot to link. I can install the glibc in /usr/lib, but if I want to use multilib, the glibc need some extra directory. As I know with the 64bit and 32bit libs can install into the /usr/lib64 and /usr/lib. But where to install the soft/hard float and big/little endian libs? 2012/9/11 Ian Lance Taylor <iant@xxxxxxxxxx>: > On Tue, Sep 11, 2012 at 6:45 AM, mei yuhua <progmei@xxxxxxxxx> wrote: >> I only need the 32 bits libs, so I think I just need to copy the >> gcc/config/mips/t-elf to gcc/config/mips/t-linux. right? > > If you add a new file, you also need to change config.gcc to use that file. > >> And how can I build the GLIBC, I think the libs need different directory. > > Cross-compiling glibc for GNU/Linux is difficult and painful.
