All of that is Steve's code and I don't know a lot about coremake and
the assorted build process (and there's zero documentation), but I do
manage to get it to compile most of the time ;)

From a fresh checkout of the foundation repository[1] in ~/foundation:

--------------------

1. Build and install coremake:

cd ~/foundationcorec/tools/coremake
make
make install

Unfortunately coremake has /usr/local/share/coremake hardcoded on Linux
for looking up its include files; therefore the "make install" is
actually really necessary.

2. Configure the rest of the project with coremake:

cd ~/foundation
coremake gcc_linux_x64

3. Compile the tools (mkvtree, mkvalidator, mkclean; optional):

cd ~/foundation
make

4. Compile the programs in spectool:

cd ~/foundation
make -C spectool

5. Use the programs:

# This creates spec.xml from specdata.xml. spec.xml is basically the
# HTML table you see on www.matroska.org/technical/specs/:

cd ~/foundation/spectools
../release/gcc_linux_x64/data2spec

--------------------

> I was able to build coremake but not sure where to go from here.

The whole foundation repo could use a serious rewrite of its build
system. Steve had reasons why he created coremake, but the result is
very, very complicated to use. If you (or anyone else) want to give such
a rewrite a try I'd highly welcome it.

I'd prefer established technologies like XSLT in this case as it allows
you to use a plethora of proven tools like xsltproc or any other XSLT
processor (Saxon?). You can (and should) still build the tools with the
instructions above so that you verify stuff works :)

Kind regards,
