What are the SCons alternatives?

I have projects in C++, Java and Python. Projects in C++ export SWIG interfaces so they can be used by Java and Python projects.

My question is: what building mechanism can I use to manage dependencies and build these projects?

I have used SCons and GYP. They are fairly easy to use and allow plugins (code-generators, compilers, packers). I'd like to know whether there are alternatives, in particular with native support for C++, Java and Python.

I develop in Linux platform, but I'd like to be able to build in mac and win platforms as well.

One promising alternative is waf:

Others:

• http://code.google.com/p/fabricate/
