MutekH is a flexible kernel, with most configuration tweaks resolved at
compile time. Therefore, it can only be distributed as source. There is
no library building involved.

Somes pages of this wiki refer to specific versions of the MutekH source
tree. This is intended. Here, we'll provide general installation notes,
therefore, we'll never use an explicit revision.

= Prerequisites to build MutekH =

== For a Linux host (as a process) ==

In order to compile MutekH as a process, like described in QuickStartUnix,
you only need a working GCC and the header files for your libc. Please
refer to your distribution manual to know more about this.

== For SoCLib and other embedded platforms ==

For embedded platforms, you'll need:
 * a working cross-compiler for your target architecture; you may either
   follow soclib:InstallationNotes, or use [source:trunk/mutekh/tools/crossgen.mk@1269 tools/crossgen.mk], see below
 * `dtc`, an utility to handle [FlattenedDeviceTree device trees], available at http://git.jdl.com/software/.


= Getting MutekH =

This is a simple svn checkout. Pay attention there are some subversion
clients that cannot handle [http://svnbook.red-bean.com/en/1.0/ch07s03.html svn:externals]
feature. In doubt, a vanilla svn client is recommended.

{{{
svn co https://www.mutekh.org/svn/mutekh/trunk/mutekh
}}}

If you need an explicit revision, simply add {{{-r number}}} to the command
line:

{{{
svn co -r 1234 https://www.mutekh.org/svn/mutekh/trunk/mutekh
}}}


= Building cross-compilers =

SoCLib installation nodes already provides a way to get cross-compilers,
if you don't already have them, MutekH holds a tool
to build a complete cross-compilation toolchain:

The script is in [source:trunk/mutekh/tools/crossgen.mk tools/crossgen.mk].

There is an inline help:
{{{
 $ tools/crossgen.mk
[prints some help]
}}}

You can try a line like this one to get a Mips cross-compiler:
{{{
 $ tools/crossgen.mk all TARGET=mipsel-unknown-elf
}}}
