Error when compiling a Gtk app (gi) with Nuitka 1.1.6 on Windows

Hello,

I had an issue compiling a GTK application on Windows with the latest Nuitka version. It used to work with Nuitka 0.6.13 and an older GTK3 version¹ but I am trying to upgrade the stack (GTK3 version, Nuitka,…).

I use gvsbuild 2022.04.1 to build GTK3. Nuitka (and Python / OS /…) versions are:

$ python -m nuitka --version
1.1.6
Commercial: None
Python: 3.9.5 (tags/v3.9.5:0a7dcbd, May  3 2021, 17:27:52) [MSC v.1928 64 bit (AMD64)]
Flavor: Unknown
Executable: C:\Users\vm0\Desktop\yoga-image-optimizer\build\__env__\Scripts\python.exe
OS: Windows
Arch: x86_64
WindowsRelease: 10

I installed Python using the official installer form python.org and Nuitka was installed in a virtualenv using pip: pip install nuitka==1.1.6

Here is the list of all dependencies I have in the venv dedicated to the build:

$ python -m pip freeze
argcomplete==1.12.3
cffi==1.15.1
colorama==0.4.5
colorlog==4.8.0
distlib==0.3.6
filelock==3.8.0
imagequant==1.0.3
mozjpeg-lossless-optimization==1.1.1
nox==2020.12.31
Nuitka==1.1.6
Pillow==9.2.0
platformdirs==2.5.2
py==1.11.0
pycairo==1.21.0
pycparser==2.21
PyGObject==3.42.2
pyguetzli==1.0.11
Unidecode==1.3.6
virtualenv==20.16.5
yoga==1.2.1
yoga-image-optimizer @ file:///C:/Users/vm0/Desktop/yoga-image-optimizer
zopflipy==1.7

Here is the output of the build:

I can reproduce the issue with the following minimal example file:

from gi.repository import Gtk

compiled with the following options:

$ python -m nuitka --standalone --plugin-enable=gi example.py

---

¹ It used to work with Nuitka 0.6.13 without the --plugin-enable=gi option (I imported manually the hidden imports of gi overrides)

Thanks for spotting that, I will include it in 1.1.7 which should be coming shortly.

Thank you very much for all your work on Nuitka! 😃
