#!/bin/sh # # This script builds and installs binutils, gcc and newlib in the order # necessary for the whole thing to work. The present version is based # on OsmocomBB's gnu-arm-build.2.sh script, which is in turn based on # yet another source. The present version has been concocted by # Spacefalcon the Outlaw for use in the FreeCalypso project. # # This script needs to be invoked with two arguments: # # $1: the path to the directory containing the upstream binutils, gcc # and newlib source tarballs; # # $2: the path to the directory where the built toolchain should be # installed. # # Note that there isn't a single install step at the end, instead this # script will build and install one component, then proceed to build the # next component which depends on the previous one, etc. For this reason # you should create a dedicated install directory that is writable by your # regular (non-root) uid, then run this script to populate that directory # with the toolchain. if [ $# != 2 ] then echo "usage: $0 path-to-tarballs path-to-install" exit 1 fi set -ex target_args="--target=arm-elf" # binutils come first tar xjf $1/binutils-2.21.1a.tar.bz2 # apply patches patch binutils-2.21.1/bfd/elf32-arm.c < binutils-patches/elf32-arm.patch mkdir -p binutils-build cd binutils-build ../binutils-2.21.1/configure --prefix=$2 ${target_args} --disable-nls make all make install cd .. # unpack gcc and newlib sources at the same time: the gcc build # will be pointed to newlib headers gcc_version=4.5.4 newlib_version=2.0.0 tar xjf $1/gcc-core-${gcc_version}.tar.bz2 tar xzf $1/newlib-${newlib_version}.tar.gz # patch gcc as needed cp t-arm-elf gcc-${gcc_version}/gcc/config/arm # gcc depends on binutils - add our install destination dir to the PATH # we prepend it to avoid surprises if some other arm-elf- toolchain # happens to be present already PATH=$2/bin:$PATH export PATH mkdir -p gcc-build cd gcc-build ../gcc-${gcc_version}/configure --prefix=$2 ${target_args} \ --enable-interwork --enable-multilib \ --with-cpu=arm7tdmi --with-float=soft \ --enable-languages=c --with-newlib \ --with-headers=`pwd`/newlib-${newlib_version}/newlib/libc/include \ --with-system-zlib --disable-shared \ --disable-nls make all-gcc make install-gcc cd .. # now we can build newlib mkdir newlib-build cd newlib-build ../newlib-${newlib_version}/configure --prefix=$2 ${target_args} \ --enable-interwork --enable-multilib \ --enable-target-optspace --enable-newlib-reent-small \ --disable-newlib-supplied-syscalls \ --disable-nls make all make install cd .. # and finally, libgcc cd gcc-build make all make install cd ..
