How to install python bindings?

[JoelSjogren]

Hello,

I have tried installing the python bindings (actually, I enabled all optional things :). I got no direct error messages from make or make install but python cannot find mgba.

I tried import mgba and import gba. Does the PYTHONPATH need to be modified? It is currently /usr/local/lib/python3.6/site-packages:/usr/local/lib/python3.6/site-packages

The qt executable works very well. I am building from git, version 0.7-5037-523fb63c, running on arch linux, with a modern intel cpu and msi gpu.

Relevant part of the make install output: (the only place I saw python mentioned)

I also tried sudo python3 setup.py develop.

It seems like package init file '/home/joel/Documents/pokemon/mgba/src/platform/python/__init__.py' not found (or not a regular file) could be the crucial warning message. Should python/__init__.py be python/mgba/__init__.py?

[endrift]

weird. pip install -e python from your build root should get it working.

Is that the right pip for python3? It can raise an error if it can't the shared lib, but...not that one.

[JoelSjogren]

Yes, it is pip for python3.

[JoelSjogren]

I am writing from a virtualbox machine now, running ubuntu 17.10. The error is reproducable with cmake .. -DBUILD_PYTHON=ON -DBUILD_QT=OFF -DCMAKE_INSTALL_PREFIX:PATH=/usr make -j4 sudo make install sudo pip3 install -e python

Could you try installing ubuntu in a virtual machine to reproduce the problem? I can send you vdi a disk image if you want but it's about 8 GB.

[endrift]

I am not in a position to try reproduce on Linux right now. Maybe next weekend.

[endrift]

Just pushed a potential fix. Try it out.

[JoelSjogren]

I think there is some progress, since make now produces the following. But python still doesn't find the package. I still get ModuleNotFoundError: No module named 'mgba'. I have removed the build root and re-run the 4 commands from my last message.

Maybe this file is of interest: build/python/dist/mgba-0.7.0.tar.gz build/python/dist/mgba-0.7.0.tar.gz

Aside from that, I just realized that mgba can be imported without need to install it (edit: one still needs to install it, but the error of python not finding mgba is circumvented) if the current working directory is src/platform/python. This seems to work (but only if imported from the python repl loop...). Based on https://gist.github.com/endrift/752230729cbf2e29192dbe2c4a5e86c2,

os.chdir('/home/joel/Documents/pokemon/mgba/src/platform/python')
from mgba import core,image
c=core.loadPath('/home/joel/Documents/pokemon/pokemon-ruby.gba')
i=image.Image(*c.desiredVideoDimensions())
c.setVideoBuffer(i)
c.reset()
for x in range(800): c.runFrame()
with open('/home/joel/Documents/pokemon/out-ruby.png', 'wb') as f:
    i.savePNG(f)
