crashes on startup with 'module' object has no attribute 'sizeof'

[blaisepascal]

After installing and building from source on Ubuntu 13.04, running it gets me the following error:

importing koko.glcanvasNo handlers could be found for logger "OpenGL.arrays.numpymodule"

I recently changed the python package build order (on the wiki) from sudo pip install PyOpenGL PyOpenGL_accelerate numpy to sudo pip install numpy PyOpenGL PyOpenGL_accelerate so that PyOpenGL knows about numpy. Do you remember which order you used?

If it was the former, you should try uninstalling and re-installing the OpenGL packages (sudo pip uninstall PyOpenGL PyOpenGL_accelerate; sudo pip install PyOpenGL PyOpenGL_accelerate) so that they can to link against the install numpy package.

[blaisepascal]

I didn't remember which order I used, but now that I'm home, my shell's command history remembered for me.

I used sudo pip install numpy PyOpenGL PyOpenGL_accelerate

I'll try uninstall/reinstall anyway, but if the order I did was correct, it shouldn't help.

Now I get:

I'm investigating if there's something wrong with my OpenGL setup, but I don't seem to have problems with other applications.

Have you pulled recently? Rahji saw the same error message and my changes in 823a93438d9c5f75e16d19339a9ab96e5d971b0c resolved his issue.

After a pull, a "make clean", a minor grumbling that no "clean" target exists in the makefile, a "rm -rf build; make; sudo make install", and a reattempt at running, I'm on to the next error:

For the record, I'm running Raring Ringtail (Ubuntu 13.04) on an AMD system (A6, Radeon HD 7540D).

What is the best way to cleanly rebuild kokopelli after a git pull?

[mkeeter]

I'm on an Nvidia card, and it looks like they are more forgiving about implicitly casting ints to floats -- see if 472a78b0775578b1218d96b50fd2751c2c9de187 resolves your problem.

I also added a make clean target, but CMake (which is used under the Makefile's hood) is pretty good at tracking dependancies -- make; sudo make install should be enough.

[blaisepascal]

That did it. it now runs. Now I get to figure out how it works.
