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

回答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.

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 :-)

回答3:

If you have tried this:

$ sudo easy_install autopy

Another option is to compile from the latest source on the GitHub repository:

$ git clone git://github.com/msanders/autopy.git

$ cd autopy

$ python setup.py build

$ python setup.py install

When building from source, make sure to cd out of the autopy directory before attempting to use AutoPy or else it may fail on an ImportError due to Python's relative imports.
