Any C/C++ to non-native bytecode compiler/interpreters?

As the title indicates, are there any C/C++ bytecode compilers/interpreters? I'm writing an application in an interpreted language that depends on certain libraries that are fully cross-compilable (there are no special flags to indicate code changes during compilation for a certain platform) but are written in C and C++. Rather than shipping n-platform-specific-libs with 开发者_StackOverflow社区each platform, it would be nice to ship one set of libs which are interpreted by one platform specific interpreter.

Possible and/or available?

EDIT1: The interpreted language in question is Python, though I may also use Ruby.

Which interpreted language are you using? If it has a .NET based implementation (e.g. IronPython) you could possibly use it with the C++/CLI compiler to produce byte code for the .NET CLR and Mono.

This is only likely to be feasible if you have full control over your C++ libraries.

If you are not sure about using the .NET VM/CLR, then you could give the Java VM a try with LLJVM (via llvm-gcc) and either Jython or JRuby.
