| 2 | 13 | ahuemer | h2. GNU ARM toolchain |
| 3 | |||
| 4 | |||
| 5 | 1 | steve-m | This page will describe the procedure for compiling a GNU ARM toolchain. |
| 6 | We will build a toolchain consisting of: |
||
| 7 | 12 | ahuemer | |
| 8 | 13 | ahuemer | * GCC 4.8.2 |
| 9 | * Binutils 2.21.1 |
||
| 10 | * Newlib 1.19 |
||

| 12 | |||
| 13 | 13 | ahuemer | h3. Getting the buildscript |
| 14 | |||
| 15 | |||
| 16 | 1 | steve-m | First of all, create a directory you want to use for building the toolchain, and download the buildscript [raw-attachment:gnu-arm-build.3.sh] there. |
| 17 | You will need to make it executable: |
||
| 18 | |||
| 19 | 13 | ahuemer | <pre> |
| 20 | 1 | steve-m | $ chmod +x gnu-arm-build.3.sh |
| 21 | 13 | ahuemer | </pre> |
| 22 | 1 | steve-m | |
| 23 | |||
| 24 | 13 | ahuemer | h3. Dependencies |
| 25 | |||
| 26 | |||
| 27 | 1 | steve-m | In order to build the toolchain, you will need to install the following packages (assuming you're using a Debian-based distribution): |
| 28 | |||
| 29 | 13 | ahuemer | <pre> |
| 30 | 10 | vogelchr | $ sudo apt-get install build-essential libgmp3-dev libmpfr-dev libx11-6 libx11-dev texinfo flex bison libncurses5 \ |
| 31 | 1 | steve-m | libncurses5-dbg libncurses5-dev libncursesw5 libncursesw5-dbg libncursesw5-dev zlibc zlib1g-dev libmpfr4 libmpc-dev |
| 32 | 13 | ahuemer | </pre> |
| 33 | 1 | steve-m | |
| 34 | |||
| 35 | 13 | ahuemer | h3. Preparation |
| 36 | |||
| 37 | |||
| 38 | 1 | steve-m | Open a shell in the directory of gnu-arm-build.sh and create the following directories: |
| 39 | |||
| 40 | 13 | ahuemer | <pre> |
| 41 | 1 | steve-m | $ mkdir build install src |
| 42 | 13 | ahuemer | </pre> |
| 43 | 1 | steve-m | |
| 44 | Download the needed sources to src/: |
||
| 45 | |||
| 46 | 13 | ahuemer | <pre> |
| 47 | 6 | steve-m | $ cd src/ |
| 48 | 1 | steve-m | $ wget http://ftp.gnu.org/gnu/gcc/gcc-4.8.2/gcc-4.8.2.tar.bz2 |
| 49 | $ wget http://ftp.gnu.org/gnu/binutils/binutils-2.21.1a.tar.bz2 |
||
| 50 | $ wget ftp://sources.redhat.com/pub/newlib/newlib-1.19.0.tar.gz |
||
| 51 | 13 | ahuemer | </pre> |
| 52 | 1 | steve-m | |
| 53 | 16 | stsp | On Ubuntu 18.04, tweak the build script such that it applies attachment:gcc-4.8.2-ubuntu-18-04.diff after unpacking gcc sources. |
| 54 | 12 | ahuemer | |
| 55 | 13 | ahuemer | h3. Building the toolchain |
| 56 | |||
| 57 | |||
| 58 | <pre> |
||
| 59 | 1 | steve-m | $ cd .. |
| 60 | $ ./gnu-arm-build.3.sh |
||
| 61 | I will build an arm-none-eabi cross-compiler: |
||
| 62 | |||
| 63 | Prefix: <YOURPATH>/install |
||
| 64 | Sources: <YOURPATH>/src |
||
| 65 | Build files: <YOURPATH>/build |
||
| 66 | |||
| 67 | Press ^C now if you do NOT want to do this. |
||
| 68 | 13 | ahuemer | </pre> |
| 69 | 1 | steve-m | |
| 70 | Hit enter and after some time hopefully end up with: |
||
| 71 | |||
| 72 | 13 | ahuemer | <pre> |
| 73 | 1 | steve-m | Build complete! Add <YOURPATH>/bin to your PATH to make arm-none-eabi-gcc and friends |
| 74 | accessible directly. |
||
| 75 | 13 | ahuemer | </pre> |
| 76 | 12 | ahuemer | |
| 77 | 13 | ahuemer | h3. Making it accessible |
| 78 | |||
| 79 | |||
| 80 | 1 | steve-m | If you're using bash, you can add the following in your ~/.bashrc file: |
| 81 | |||
| 82 | 13 | ahuemer | <pre> |
| 83 | 1 | steve-m | export PATH=$PATH:<YOURPATH>/install/bin |
| 84 | 13 | ahuemer | </pre> |
| 85 | 1 | steve-m | |
| 86 | 14 | laforge | That's it. You can build [[OsmocomBB]] now (see [[Software Getting Started]]). |

| 90 | 13 | ahuemer | This script is a slightly updated/modified version of the script found "here":http://hobbycode.googlecode.com/svn/trunk/gnu-arm-installer/. |
| 91 | |||
| 92 | 1 | steve-m | 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. |
