Following step-by-step instructions by Adam J. Kunen I was able to compile my own gnu arm tool-chain on Ubuntu Linux 12.10.
I used following packages:
- gcc-4.8.1 (Adam also recommends downloading packages gcc-core and g++ but I skipped those)
../../src/gcc-4.8.1/configure --target=arm-none-eabi --prefix=$MYTOOLS --enable-interwork --enable-multilib --enable-languages="c,c++" --with-newlib --with-headers=../../src/newlib-2.0.0/newlib/libc/include --with-system-zlib
UPDATE: Unfortunately this fix has some issues. It will not build libgcc. Seeking for a better solution.
