[visionegg] Re: Python and VisionEgg on OS X Tiger

I had a different problem with VisionEgg and Tiger.

When attempting to build VisionEgg, I get conflicting type errors about _darwin_maxpriority. Turns out that the argument types for getpriority and setpriority have changed slightly in Tiger (which isn't reflected in the manpages for the two functions either). Basically, the second arguments to getpriority and setpriority change from an "int" to an "id_t" (whatever that is).

The diff with the SWIG file is at the end of this e-mail. I'm not sure how to seamless integrate this into the codebase, because obviously making this change will break things on versions of OS X less than Tiger; since I haven't really ever used SWIG before, I'm not sure how to conditionally make these changes only for Tiger.

Hi Everyone,

I've done some work to get things running after an Upgrade to Tiger seemed to break access to the site-packages directory in the included python 2.3.5 with Tiger.

The issue is a simple one to fix, and there is a downloadable workaround. The long winded explanation to what has broken is available here: http://bob.pythonmac.org/archives/2005/05/01/python- on-mac-os-x-104-tiger/

Simply put, the symlink to /Library/Python/2.3/site-packages no longer worked with OS X Tiger. A downloadable fix (which I've attached) inserts a new .pth file in the site-packages directory that will point to the old site-packages directory.

The attached file is called TigerPython23Compat.pkg.zip and can be found with a quick google search.

Cheers,

Kevin
