| 3 | 20 | fixeria | To compile the target firmware for [[OsmocomBB]] or [[SIMtrace:]], you need a GNU toolchain for ARM. You can either use binary packages provided by your distribution (recommended), or build a toolchain from source code yourself. There are various pre-compiled toolchains available (e.g. Code Sourcery), 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. |

| 7 | 12 | fixeria | You can use a pre-compiled toolchain provided by your GNU/Linux distribution. |

| 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 | 19 | fixeria | $ sudo pacman -S arm-none-eabi-gcc arm-none-eabi-newlib |
| 19 | 12 | fixeria | </pre> |
| 20 | 1 | tsaitgaist | |
| 21 | 20 | fixeria | The following versions are confirmed to work: |
| 22 | 1 | tsaitgaist | |
| 23 | 20 | fixeria | <pre> |
| 24 | Name : arm-none-eabi-gcc |
||
| 25 | Version : 10.2.0-1 |
||
| 26 | --- |
||
| 27 | Name : arm-none-eabi-binutils |
||
| 28 | Version : 2.34-1 |
||
| 29 | --- |
||
| 30 | Name : arm-none-eabi-newlib |
||
| 31 | Version : 3.3.0-1 |
||
| 32 | </pre> |
||

| 34 | 20 | fixeria | h3. Building from source |
| 35 | |||
| 36 | If a pre-compiled toolchain provided by your distribution fails to produce working firmware images, you can build your own toolchain known to be working with [[OsmocomBB]], see here: [[GnuArmToolchain]]. |
||
| 37 | 17 | fixeria | |
| 38 | h3. Building old branches |
||
| 39 | |||
| 40 | 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. |
||
| 41 | |||
| 42 | Please follow the build instructions at: https://github.com/axilirator/gnu-arm-installer/ |
||
| 43 | |||
| 44 | 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. |
||
| 45 | This issue has been fixed in master: http://cgit.osmocom.org/osmocom-bb/commit/?id=a903b3c1ee27047c79728b18ff6340d23d1aad2e. |

| 47 | 1 | tsaitgaist | h3. Mac OS X |
| 48 | |||
| 49 | 17 | fixeria | Apparently the arm-elf-gcc 4.3.2 from ports for MacOS X can compile the firmware 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_. If you omit the links, there will be unresolvable references to symbols in the libraries. |
