Errors while installing python autopy

Question

Hey I have looked at and old question here but it doesn't answer my question

Can anyone help. I need autopy as it works on multiple platforms

I used ethan.tira-thompson.com/Mac_OS_X_Ports.html to install libpng

Have xcode installed with command line tools as well

Answer 1

I had the same problem, if you notice all 9 errors are coming from one file: src/screengrab.c This file has not been updated to the latest version of OpenGL and there are deprecated methods. On the autopy github repo there is a bug reported for this here. The fix/hack suggested there is to add the line: #include <OpenGL/gl.h>

after line 7 in src/screengrab.c. You are going to have to get the source from Github and alter it locally rather than using easy_install.
Note this is a hack that will get it to compile but the screen grabs will be all black. Someone needs to spend a few minutes rewriting screengrab.c with up to date methods.

Answer 2

When I added

#include <OpenGL/gl.h>

It did not compile.

So, I took a look though my hard disk, looking for each gl.h

So, I tried

    #include "/System/Library/Frameworks/OpenGL.framework/Versions/A/Headers/gl.h"

Then I managed to compile it :-)
