[Pyobjc-dev] py2app builds fail leopard codesign integrity checks

[James R E. <ea...@ba...>]

Hi folks,

It appears that PyObjC applications built with py2app on Leopard fail  
the codesign integrity checks.  I have an application that uses a  
simple ObjC wrapper around the SecKeychain{Add,Find}GenericPassword  
methods.  When I build and run the application from an XCode project,  
the application runs fine, adding and finding passwords on the  
keychain.  When I build and run the same project using py2app, Leopard  
gripes when reading from the Keychain:

"KeychainError - code or signature modified"

At first I thought it might be the stripping phase, since I see the  
following warning when building, but the keychain error arises even if  
I pass --no-strip to py2app.  In my case, it's easy enough to work- 
around by using XCode, but is this a known bug in py2app or something  
I might be doing wrong.  (If it's the latter, I'd be happy to provide  
a small demonstration app, if necessary.)

Thanks!
James
