Feature #1323
closedInclude Python static libraries to build Python-C extensions with static linking
100%
Description
Currently Python 2.7/3.5 in CrystaX NDK include only shared Python libs libpythonX.X.so. I'd like to be able to build Python-C statically-linked extensions with no external dependencies. Please include static libs libpythonX.X.a as well.

Yes, we've thought about it. There was several issues preventing us from doing that initially, but you're right, this is useful feature so we'd make it. I just can't promise it would be soon.

step-1)
In order to have full control over static python libraries and more over to be able to play with python byte-code in any games,
first of all we need to have host pythons of the same major versions as we already have for target - python2.7 and python3.5
This task is almost done - remaining part https://tracker.crystax.net/issues/1354
step-2)
Build target python core as static library.
This static is expected to self-consistent but with one external symbol - struct _frozen PyImport_FrozenModules[]
step-3)
Now we can play with content of PyImport_FrozenModules[] and provide different levels of frozen modules:
- level-0) Absolute minimal content for PyImport_FrozenModules - means you need nothing except static python core
- level-1) Full content for PyImport_FrozenModules - means you have full access to python stdlib prebuilt as bytecode
- level-2) Custom content for PyImport_FrozenModules - nearly the same what different freezing toools do (like cx_Freeze or others)

Custom content for PyImport_FrozenModules
To make sure that everything works well here I decided to compile a completely static python interpreter without depends on any dynamic libraries. In this interpreter PyImport_FrozenModules list is filled full python-stdlib being frozen as byte-code.
Actual python-freezing tool adapted for CrystaX can be implemented lately when it is really needed - not as a part of this task.
