Depending on the target, MutekH requires different toolchains.

Default toolchains

SoCLib

For SoCLib targets, the MutekH build system uses the ​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
