[edit] Prerequisites

For a complete ARM7 toolchain you will need:

• binutils 2.18
• gcc-core 4.2.1
• newlib 1.15.0
• gdb 6.6

[edit] Building the toolchain

[edit] binutils

% tar xjf binutils-2.18.tar.bz2
% cd binutils-2.18
%  ./configure --prefix=/usr/local/arm --target=arm-elf --enable-interwork --enable-multilib
 [...]
% make
 [...]
% make install
 [...]

[edit] gcc

Attention: Extract newlib to some directory before, and specify that on the configure-call using "--with-build-sysroot=NEWLIB_DIR/newlib/libc/include"

% tar xjf gcc-core-4.1.2.tar.bz2
% cd gcc-4.1.2/
% mkdir arm-obj
% cd arm-obj 
% ../configure --prefix=/usr/local/arm --target=arm-elf --enable-interwork --enable-multilib --enable-languages=c --with-newlib --without-ssp --disable-libssp --with-build-sysroot=NEWLIB_DIR/newlib/libc/include
 [...]
% make
 [...]
% make install
 [...]
