nuitka fails to find Python headers

[ghost]

I'm trying to use nuitka with mingw-w64-i686-python3 under msys2 but it throws up errors asking for .h files, is there a python3-dev package anywhere I can use? I have it working on a normal python setup so my compiler is setup correctly (visual studio and mingw-64.)

[ghost]

Just to confirm it is getting as far as the compiler before showing the error needing .h files.

@Azza-NZ what package you use MSYS-python or MINGW-python? Also what GCC used MINGW-GCC or MSYS-GCC?

You need MINGW GCC for MINGW PYTHON3

I somehow installed the needed dev files, but it simply asked for more source files "crypt.h" , this page says it's known it's missing from mingw.

https://www.gnu.org/software/gnulib/manual/html_node/crypt_002eh.html

I was doing this because I wanted to use Python 3.7.2 with PyGobject and Nuitka, was anyone succesfully done that?

[EchterAgo]

I likely had this problem too. A package I tried to compile picked up the MSYS Python.h instead of the MinGW one. For me it was enough to remove the python package. You need to install mingw-w64-x86_64-python3 (depending on whether you need 32/64 bits and Python 2 or 3)

I only get this, so likely nuitka is broken..

$ CC=gcc nuitka3 a.py

scons: warning: MSVC_USE_SCRIPT set to False, assuming environment set correctly.
File "C:/msys64/mingw32/lib/python3.7/site-packages/nuitka/build/inline_copy/lib/scons-3.0.4\SCons\Script\Main.py", line 609, in _scons_internal_warning

Yes, Nuitka has a few problems with this setup. I've got it working, under wine, and will post updates/patches referencing https://github.com/Nuitka/Nuitka/issues/43

[jayvdb]

Python 3.8 is in RC1 now.

Will it be replacing Python 3.7 when it is stable and all mingw Python packages build & pass smoke tests on it?

Or will it be a separate package which can be a bit experimental?

This is regarding Nuitka support of static standalone, which I would ideally like to solve at the same time https://github.com/Nuitka/Nuitka/issues/95

It might be easier to solve in Python 3.8 - still investigating that.

[lazka]

It'll replace 3.7, but it might take some time after the release to rebase our changes. 3.8 changed they way Python loads binary extensions on Windows, so that could result in additional work.

Still no solution to this?

[lazka]

I still get

CC=gcc nuitka3 g.py
Error, no 'Python.h' development headers can be found at 'C:/msys64/mingw64/include', dependency not satisfied!

so likely nothing has changed.

[kuznetsov-m]

OS Ubuntu 18.40 Python 3.8.0 nuitka 0.6.9.4

Also:

Scons: Compiler used /usr/bin/gcc
Error, no 'Python.h' development headers can be found at 'C:/msys64/mingw64/include', dependency not satisfied!

Not sure what you guys are doing, checkout Nuitka/Nuitka#872 where I found it to be working out of the box with the correct packages installed, these being python-devel python gcc. Just don't use MinGW if you are not on Win32.

@podsvirov Was it fixed?
