There are pretty succinct cross-compiler instructions on gnuarm.org, including how to use newlib, even if ARM is not your target. In config.log, find "suffix of object files". Nearby, you'll find what it actually did to try to figure that out, including showing the compiler commandline and output. Try to figure out why the compiler puked, and post here again if you still need help. -----Original Message----- From: gcc-help-owner@xxxxxxxxxxx [mailto:gcc-help-owner@xxxxxxxxxxx] On Behalf Of Eduardo Brito Sent: Friday, October 17, 2008 1:18 PM To: gcc-help@xxxxxxxxxxx Subject: Re: Problem building cross-compiler for mips John Love-Jensen escreveu: > Hi Eduardo, > > >> I'm using the following commands: >> ./configure --target=mipsel-elf --prefix=/usr/local/ ... >> > ..^^ > > As mentioned in the GCC documentation... > > http://gcc.gnu.org/install/ > http://gcc.gnu.org/install/configure.html > > ...running configure in the self-same directory of the GCC source code is > not supported.

Also, I think I should use newlib with the cross compiler... How can I do that? Thanks, Eduardo
