How to best compile C++/Cython project into an executable?

I have a project with a bunch of C++ and Python/Cython files. Until now I primary developed the C++ part and compiled it to a static library with qmake. Some few methods are exposed with boost::python, and executed from a .py file.

I now wanted to compile the whole thing into a standalone executable.

My question now: what is the best way to do this? I tried to switch to Cython, compile the python files and linking the library. But it seems there is no direct way with distutils/setup.py to compile an executable, only shared libraries.

Is there a way to easily compile both .cpp and .pyx files into an executable at once?

So that I can get rid of a lot of the boost::python wrapper stuff and get a neat mix of c++/python without having to import a shared library and pack the whole stuff with pyinstaller?

You should look into:

Since python is your entry point, you will be able to bundle a stand-alone interpreter, environment, and resource location into an app/exe/binary. It will collect all your library modules into its self-contained site-packages

If you don't use any normal pure py files and only have cython files, then it is also possible to embed an interpreter into one of them as an entry point with an --embed flag to cython: http://wiki.cython.org/EmbeddingCython
Note, this is a similar "freeze" approach to the previously mentioned packaging options, but doesn't go the extra length to build a self contained env
