I don't know but I played around with Rake for a while to build C/C++
and found it unsuitable. Whilst Rake is a great dependency tracking
system for tasks it is not so great a tool for a general build system. I
ended up turning to SCons which is a Python package though I prefer to
do my general scripting in Ruby.
The things that SCons does better
- Construction environments
- Hierarchical project management
- Automatic clean rules
- The ability to glob the dependency tree as well as the file system
which is great for
when using code generators
- Many builders for C/C++/Fortran and others come by default with the
SCons package. Most of the builders
are automatically cross platform too. Windows/Linux builds are done
with exactly the same commands.
That being said I think the Rake notation is nicer than SCons because
Ruby is a nicer language. However Rake seems to be used primarily in
Ruby based projects and there is not much development effort in making
it friendly to other areas. This is not a criticism. Rake seems
extremely good at what it does for the customers that use it. However
for a general build engine I would recommend at least a look at SCons.
