1 | 1 | tsaitgaist | To compile osmocomBB or SIMtrace for the target we need a GNU Toolchain for ARM. |
---|---|---|---|
2 | There are various pre-compiled toolchains available but not all of them will produce working firmware. |
||
3 | We will try to support all these configurations but it might take a while to identify the source of a problem. |
||
4 | |||
5 | 5 | tsaitgaist | If you have persistent errors when compiling, try using a different package. |

10 | 6 | tsaitgaist | If you want to build your own toolchain, known to be working with OsmocomBB, see here: [wiki:GnuArmToolchain]. |
11 | 1 | tsaitgaist | |
12 | 6 | tsaitgaist | This is the best option to get a fairly recent GCC, and this is the option used by several Osmocom-BB developers. |
13 | |||
14 | |||
15 | === GNUArm === |
||
16 | |||
17 | The toolchains that are known working are the [http://www.gnuarm.com GNUArm.com] ones. Only x86_64 versions are usable [http://gnuarm.com/bu-2.16.1_gcc-4.0.2-c-c++_nl-1.14.0_gi-6.4_x86-64.tar.bz2 here]. The ones for x86 are based on 3.4.3 which it too old to compile Osmocom-BB properly. |

19 | 1 | tsaitgaist | For amd64 |
20 | {{{ |
||
21 | wget http://www.gnuarm.com/bu-2.16.1_gcc-4.0.2-c-c++_nl-1.14.0_gi-6.4_x86-64.tar.bz2 |
||
22 | tar xf bu-*_gcc-*-c-c++_nl-*_gi-*_x86-64.tar.bz2 |
||
23 | mv gnuarm-* ~/gnuarm |
||
24 | }}} |
||
25 | |||
26 | To be able to use the toolchain, add the crosscompilers to your PATH |
||
27 | {{{ |
||
28 | export PATH=~/gnuarm/bin:$PATH |
||
29 | }}} |

32 | === Ubuntu packages === |
||
33 | gnuarm packages from following ppa are known to work on ubuntu 10.10 to build osmocom-bb. They are known '''not''' to work for SIMtrace |

44 | === Mac OS X === |
||
45 | |||
46 | 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. |
