== GNU ARM toolchain == 

 This page will describe the procedure for compiling a GNU ARM toolchain. 
 We will build a toolchain consisting of: 

  * GCC 4.5.2 
  * Binutils 2.21 
  * Newlib 1.19 

 === Getting the buildscript === 

 First of all, create a directory you want to use for building the toolchain, and download the buildscript [raw-attachment:gnu-arm-build.sh]    there. 
 You will need to make it executable: 

 {{{ 
 $ chmod +x gnu-arm-build.sh 
 }}} 

 === Dependencies === 

 In order to build the toolchain, you will need to install the following packages (assuming you're using a Debian-based distribution): 

 {{{ 
 $ sudo apt-get install build-essential libgmp3-dev libmpfr-dev libx11-6 libx11-dev texinfo flex bison libncurses5 \ 
   libncurses5-dbg libncurses5-dev libncursesw5 libncursesw5-dbg libncursesw5-dev zlibc libmpfr4 libmpfr-dev libmpc-dev 
 }}} 

 === Preparation === 

 Open a shell in the directory of gnu-arm-build.sh and create the following directories: 

 {{{ 
 $ mkdir build install src 
 }}} 

 Download the needed sources to src/: 

 {{{ 
 $ cd src/ 
 $ wget http://ftp.gnu.org/gnu/gcc/gcc-4.5.2/gcc-4.5.2.tar.bz2 
 $ wget http://ftp.gnu.org/gnu/binutils/binutils-2.21.tar.bz2 
 $ wget ftp://sources.redhat.com/pub/newlib/newlib-1.19.0.tar.gz 
 }}} 

 === Building the toolchain === 

 {{{ 
 $ cd .. 
 $ ./gnu-arm-build.sh  
 I will build an arm-elf cross-compiler: 

   Prefix: <YOURPATH>/install 
   Sources: <YOURPATH>/src 
   Build files: <YOURPATH>/build 

 Press ^C now if you do NOT want to do this. 
 }}} 

 Hit enter and after some time hopefully end up with: 

 {{{ 
 Build complete! Add <YOURPATH>/bin to your PATH to make arm-elf-gcc and friends 
 accessible directly. 
 }}} 

 === Making it accessible === 

 If you're using bash, you can add the following in your ~/.bashrc file: 

 {{{ 
 export PATH=$PATH:<YOURPATH>/install/bin 
 }}} 

 That's it. You can [GettingStarted#Gettingandupdatingthesource build] OsmocomBB now.

 This script is a slightly updated/modified version of the script found [http://hobbycode.googlecode.com/svn/trunk/gnu-arm-installer/ here]. [[BR]] 
 The original version also builds Insight, but since we don't need that, we won't build it. If you want to, just remove the comments in the shellscript.
