So I’ve decided I wanted to build a cross compiler on x86_64 install of Linux (RHEL 5) and have run into nothing but old-arse documents except for the Fine folks at Linux From Scratch where I find they have documentation on the process, but it requires some of their patches/setup to make it happen. So I’m attempting to make it so that you can do it from scratch without any outside scripts/etc.

(Work in progress)

This will be for building 32-bit SPARC code on an x86_64 system:

Compile Binutils for Cross Compilation
tar jxvf binutils-*.tar.bz2
mkdir binutils-build
cd binutils-build
AR=ar AS=as ../binutils-2*/configure --prefix=/opt/cross-compiler --host=x86_64 --target=sparc-linux --with-lib-path=/cross-compiler/lib --disable-nls --enable-shared
make configuration-host
make
make check
make install


Build GMP as prereq for gcc


Build MPFR as prereq for gcc


Build MCP as prereq for gcc
