Depending on the target, MutekH requires different toolchains.

= Default toolchains =

== SoCLib ==

For SoCLib targets, the MutekH build system uses the [https://www.soclib.fr/trac/dev/wiki/CrossCompiler SoCLib default cross-compilers].

That means it will use:
 * `mipsel-unknown-elf`
 * `powerpc-unknown-elf`
 * `arm-unknown-elf`

== x86 ==

For x86, MutekH assumes you are using a x86-elf host and uses your current compiler

== Emu ==

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.

= Use your own toolchain =

You may use your own toolchains.

== One-shot use ==

You may specify the following variables:
 `CPUTOOLS`::
   common prefix of compiler tools, usually something like `mipsel-unknown-elf-` (the last `-` is important)
 `CPUCFLAGS`::
   options for your C compiler, if you have a libc-aware compiler, you may specify `CPUCFLAGS+=-nostdinc`
 `CPULDFLAGS`::
   options for your linker, if you have a libc-aware compiler, you may specify `CPULDFLAGS+=-nostdlib`
