Re: [PyOpenGL-Users] Crash with python 3.5 on ubuntu 16.04

[Matti K. <mat...@gm...>]

I wasn't able to reproduce your error (Ubuntu 16.10), how did you 
install 3.0.2?

But before answering that! If its not a hard requirement to use 3.0.2 I 
would suggest installing and using 3.1.0 :

# remove your current pyopengl, might through synaptic or with $ sudo 
apt-get remove python3-pyopengl

$ sudo apt-get install python3-pip

$ python3 -m pip install pyopengl

...using 3.1.0 I saw no errors with your test script.

==

The most-recent code changes the line that errored out to:

def mapVBO( vbo, access=0x88BA ): # GL_READ_WRITE

If you really don't want to install 3.1.0, you could try editing 
/usr/lib/python3/dist-packages/OpenGL/arrays/vbo.py line 430 and making 
the change above-- you may find more errors though.
