py25-matplotlib dependency fails on Tiger

[jjstickel@…]

The Portfile for py25-matplotlib (and matplotlib portfile for other python versions) has a dependency for "port:py25-pyobjc2-cocoa". This dependency cannot be installed on Tiger. Here is a patch that removes this dependency for Darwin < 9.

In that case the Cocoa backends won't work on Tiger so a further patch to disable the Cocoa backends will be needed in addition to this.

How does the build of py25-pyobjc2-cocoa fail on Leopard?

Josh: Do you know of any problem with py25-pyobjc2-cocoa on Tiger?

Sorry, that should say Tiger.

[jjstickel@…]

In both the py25-pyobjc2 and py25-pyobjc2-cocoa Portfiles, there is:

if {${os.major} < 9} {
    pre-fetch {
        return -code error "PyObjC 2.0 requires Mac OS X 10.5"
    }
}

I think there was a trac ticket or email thread (not sure now) that explained the reason for this. There exists py25-pyobjc that supposedly works on Tiger (but not Leopard), but there is no py25-pyobjc-cocoa port.

[skymoo (Adam Mercer)]

Got it. I'll look into how to disable the Cocoa backends on Tiger.

[jmroot (Joshua Root)]

The deps need to be done as in e.g. py25-game. Prior to PyObjcC 2.0 the core and framework wrappers were not separate.

Fortunately upstream will soon (finally) be doing a proper release, and it looks like it will be Tiger compatible.

[skymoo (Adam Mercer)]

Can you try the attached patch to see if it builds, and the Cocoa backends work, on Tiger?

use pyobjc2 only on Leopard

The port builds and the CocoaAgg backend works now (although it crashed after I used the save file option). Probably this fix should be pushed to the py-matplotlib port.

This was on Tiger.

Great, any backtrace for the crash?

No. It was a segmentation fault. Since I plan to be using the WXAgg backend (more features), I do not have the interest to help debug the cocoa backend.

Thanks for the fix to the Portfile, though.
