Hi all, Trying to eliminate the conflict that occurs between Carbon.AE and CarbonX.AE when both extensions are loaded. The problem is that both extensions need to export the following functions for use by other extensions: AEDesc_New, AEDesc_NewBorrowed and AEDesc_Convert. The logical solution is to rename the CarbonX functions and have the other appscript-related extensions (PSN, OSA, OSATerminology) refer to those instead. Unfortunately, when I try to do this, all I get is a bunch of 'symbol not found' errors on import:
That's because there are hooks in the core interpreter for the Carbon modules. PyObjC's code contains an example of how top provide a C API to other extensions without cooperation from the Python core is to create a struct with function pointers, wrap that in a Python and extract that struct again in the other extensions.
PyObjC contains an example of how to do this (the code in pyobjc-api. [hm]).
