Hi I'm trying to cross compile GCC To save confusion here I mean I'm building GCC with a cross compiler and not building GCC as a cross compiler. I'm getting the following error while running configure: checking for correct version of gmp.h... yes checking for correct version of mpfr.h... no configure: error: Building GCC requires GMP 4.1+ and MPFR 2.3.0+. I'm at a loss for why the mpfr.h check is failing. I'm running configure with: ../gcc-4.3.3/configure --host=arm-none-linux-gnueabi --prefix=/built --with-gmp=/built --with-mpfr=/built I'm working on the assumption that this error is referring to libraries that must be available under the host environment. I've downloaded and built gmp-5.0.1 and mpfr-2.4.2 and installed them to the prefix "/built". The /built directory only contains these and binutils. Note: "--with-gmp=/built" appears to have worked... Without it the gmp.h check fails. If its relevant, I'm building with CodeSourcery 2009q3-67 for ARM GNU/Linux. Thanks for your time. Phil
