In this document I will describe how to build a toolchain for ARM.

== setup build environment ==

In this document we will install the toolchain in the users home directory under ''$HOME/arm-elf''.

Installation will take place in ''/tmp/toolchain''.


''$ mkdir -p /tmp/toolchain/src''

''$ mkdir -p /tmp/toolchain/arm-elf''

''$ mkdir -p $HOME/arm-elf/bin''

''$ export PATH=$HOME/arm-elf/bin:$PATH''


=== binutils ===

Download binutils from [[http://ftp.gnu.org/gnu/binutils/binutils-2.21.1.tar.gz]]

''$ cd /tmp/toolchain/src''

''$ wget [[http://ftp.gnu.org/gnu/binutils/binutils-2.21.1.tar.gz]]''

''$ tar -zxvf binutils-2.21.1.tar.gz''

Configure and build.

''$ cd /tmp/toolchain/arm-elf''

''$ mkdir binutils''

''$ cd binutils''

''$ ../../src/binutils-2.21.1/configure --prefix=$HOME/arm-elf --target=arm-elf --disable-nls''

''$ make''

''$ make install''






=== gcc ===

checkout trunk version of gcc from svn

''$ cd /tmp/toolchain/src''

''$ svn co svn checkout [[svn://gcc.gnu.org/svn/gcc/trunk gcc-trunk]]''

configure and build gcc

''$ cd /tmp/toolchain/arm-elf''

''$ mkdir gcc ''

''$ cd gcc ''

''$ ../../src/gcc-trunk/configure --prefix=$HOME/arm-elf --target=arm-elf --disable-werror --disable-nls --enable-interwork --enable-multilib --enable-languages="c,c++" --enable-target-optspace --with-float=soft --with-newlib --with-headers=/home/alios/src/toolchain/src/newlib/newlib/libc/include/  --with-system-zlib  --disable-shared''

''$ make''

''$ make install''

=== newlib ===

checkout newlib from cvs

''$ cd /tmp/toolchain/src''

''$ cvs -z 9 -d :pserver:anoncvs@sources.redhat.com:/cvs/src login   ## use 'anoncvs' as password ''

''$ cvs -z 9 -d :pserver:anoncvs@sources.redhat.com:/cvs/src co newlib''

configure and build

''$ cd /tmp/toolchain/arm-elf''

''$ mkdir newlib ''

''$ cd newlib ''

''$ ../../src/newlib/configure --prefix=$HOME/arm-elf --target=arm-elf --enable-interwork --enable-multilib --enable-target-optspace --with-float=soft''

''$ make''

''$ make install''
