You can find here older releases of cross compilers for i386 Linux

This is a cross compilation of GCC on Mac OS X.

A package installs all files in the given installation directory. Within the installed directory, the contents.txt file contains the detail of cross-compiled archives.

All tools are located in the bin sub directory. You can add this path to your PATH shell variable, or invoke the tools with their full path name: for example /usr/local/gcc-4.5.2-for-linux32/bin/i586-pc-linux-gcc for gcc.

For better portability of Linux tools built with theses cross compilation chains, invoke the linker with the -static option, for example:

• /usr/local/gcc-4.5.2-for-linux32/bin/i586-pc-linux-gcc -static for C linking;
• /usr/local/gcc-4.5.2-for-linux32/bin/i586-pc-linux-g++ -static for C++ linking.

Theses packages have been built with BINUTILS 2.23.2, GCC 4.8.1, GMP 4.3.2, MPC 0.8.1, MPFR 2.4.2 and GLIBC 2.11.1, for Mac OS X 10.6 and later.
