| 1 | Depending on the target, MutekH requires different toolchains. |
| 2 | |
| 3 | = Default toolchains = |
| 4 | |
| 5 | == SoCLib == |
| 6 | |
| 7 | For SoCLib targets, the MutekH build system uses the [https://www.soclib.fr/trac/dev/wiki/CrossCompiler SoCLib default cross-compilers]. |
| 8 | |
| 9 | That means it will use: |
| 10 | * `mipsel-unknown-elf` |
| 11 | * `powerpc-unknown-elf` |
| 12 | * `arm-unknown-elf` |
| 13 | |
| 14 | == x86 == |
| 15 | |
| 16 | For x86, MutekH assumes you are using a x86-elf host and uses your current compiler |
| 17 | |
| 18 | == Emu == |
| 19 | |
| 20 | For emu targets, MutekH uses you current compiler, except if you are on a Darwin host, in which case it uses a `i686-unknown-elf` toolchain in order to use ELF files. |
| 21 | |
| 22 | = Use your own toolchain = |
| 23 | |
| 24 | You may use your own toolchains. |
| 25 | |
| 26 | == One-shot use == |
| 27 | |
| 28 | You may specify the following variables: |
| 29 | `CPUTOOLS`:: |
| 30 | common prefix of compiler tools, usually something like `mipsel-unknown-elf-` (the last `-` is important) |
| 31 | `CPUCFLAGS`:: |
| 32 | options for your C compiler, if you have a libc-aware compiler, you may specify `CPUCFLAGS+=-nostdinc` |
| 33 | `CPULDFLAGS`:: |
| 34 | options for your linker, if you have a libc-aware compiler, you may specify `CPULDFLAGS+=-nostdlib` |
