How to force py2app to run app in 32-bit mode

I am trying to build an app bundle with py2app on Mac OS X 10.6. The app uses some libraries which are only compiled for 32-bit, so when the app is run there is an ImportError "no appropriate 64-bit architecture". How can I tell py2app to force the app to run in 32-bit mode?

Solution

  • One way is to use a 32-bit-only Python, such as the 32-bit-only versions downloadable from python.org, with py2app. Another is to set the LSArchitecturePriority to i386 and possibly ppc in the generated app bundle's Info.plist. See here for more info.
