| 1 | 12 | fixeria | h1. Toolchain |
|---|---|---|---|
| 2 | 1 | tsaitgaist | |
| 3 | 12 | fixeria | To compile the target firmware for [[OsmocomBB]] or [[SIMtrace:]], you need a GNU Toolchain for ARM. There are various pre-compiled toolchains available, but not all of them will produce working firmware. We're trying to support all these configurations, but it might take a while to identify the source of a problem. If you have persistent errors when compiling, try using a different package. |

| 5 | 12 | fixeria | h3. Binary distribution |
| 6 | 1 | tsaitgaist | |
| 7 | 12 | fixeria | You can use a pre-compiled toolchain provided by your GNU/Linux distribution. |
| 8 | 1 | tsaitgaist | |
| 9 | 12 | fixeria | For Debian based distributions (Ubuntu, Linux Mint, etc.), use the following command: |
| 10 | 1 | tsaitgaist | |
| 11 | 12 | fixeria | <pre> |
| 12 | $ sudo apt install gcc-arm-none-eabi |
||
| 13 | </pre> |
||

| 15 | 12 | fixeria | For ArchLinux (https://www.archlinux.org/packages/community/x86_64/arm-none-eabi-gcc/): |
| 16 | 11 | tsaitgaist | |
| 17 | 12 | fixeria | <pre> |
| 18 | $ sudo pacman -S arm-none-eabi-gcc |
||
| 19 | </pre> |
||

| 21 | 16 | fixeria | h3. Build in Docker (dockcross) |
| 22 | |||
| 23 | Please refer: https://github.com/dockcross/dockcross |
||
| 24 | |||
| 25 | <pre> |
||
| 26 | $ git clone https://github.com/dockcross/dockcross |
||
| 27 | $ cd dockcross/ |
||
| 28 | $ mkdir build/ |
||
| 29 | $ docker run --rm dockcross/linux-armv7 > build/dockcross |
||
| 30 | $ chmod +x build/dockcross |
||
| 31 | </pre> |
||
| 32 | |||
| 33 | Unfortunately, I didn't (yet) manage to build the firmware using this toolchain. Here is what I tried: |
||
| 34 | |||
| 35 | <pre> |
||
| 36 | $ cd osmocom-bb/src/ |
||
| 37 | $ $HOME/dockcross/build/dockcross make firmware |
||
| 38 | </pre> |
||
| 39 | |||
| 40 | If you know how to proceed, please update this section. |
||
| 41 | |||
| 42 | 12 | fixeria | h3. Build one from source |
| 43 | 1 | tsaitgaist | |
| 44 | 12 | fixeria | If you want to build your own toolchain, known to be working with [[OsmocomBB]], see here: [[GnuArmToolchain]]. |
| 45 | 6 | tsaitgaist | |
| 46 | 12 | fixeria | This is the best option to get a fairly recent GCC, and this is the option used by several [[OsmocomBB]] developers. |
| 47 | |||
| 48 | 13 | fixeria | h3. Building old branches |
| 49 | |||
| 50 | 14 | fixeria | If you need to build the *firmware from old unmaintained branches* (sylvain/burst_ind, sylvain/testing, jolly/testing, etc.), an older version of toolchain is needed. |
| 51 | 1 | tsaitgaist | |
| 52 | Please follow the build instructions at: https://github.com/axilirator/gnu-arm-installer/ |
||
| 53 | 15 | fixeria | |
| 54 | When using toolchain with GCC >=4.8, the firmware can be compiled, but will hang as soon as you want to sync to an ARFCN. |
||
| 55 | This issue has been fixed in master: http://cgit.osmocom.org/osmocom-bb/commit/?id=a903b3c1ee27047c79728b18ff6340d23d1aad2e. |

| 57 | 12 | fixeria | h3. Mac OS X |
| 58 | 1 | tsaitgaist | |
| 59 | Apparently the arm-elf-gcc 4.3.2 from ports for mac os x can compile the sourcecode as well after symlinking /opt/local/bin/arm-elf-ranlib to /opt/local/bin/arm-elf-linux-ranlib and /opt/local/bin/arm-elf-strip to /opt/local/bin/arm-elf-linux-strip. |
