xcode - linking against dylib built for MacOSX file '/usr/lib/libSystem.B.dylib' for architecture i386

Question

I recently switched my development MacBook from a classic MacBook (32 bit) to a MacBook Air (64 bit). I am trying to open a project that was made on my old MacBook (32 bit) running XCode 4.

The project is a PhoneGap application made in PhoneGap 1.7.0.

My new MacBook Air (64 bit) is running XCode 5.

I imported my developer profiles from my old MacBook to my new MacBook Air. But when I try to run it, I get the following error message.

I have tried changing the my architecture in the build settings to armv7 but still no luck :(

Does anyone know why I'm getting this error and how to fix it?

Thanks

Answer 1

OK so as it turns out, XCode 5 changes the default architecture to armv7 when my application does not support armv7. I am running Cordova 1.7.0 and that version does not have support for armv7 architecture.

Fix architecture issue:

1. Removed ALL architectures from Build Settings --> Valid Architecture
2. Added armv6 to Build Settings --> Valid Architecture

Fix libSystem.B.dylib issue:

3. Removed /usr/lib/libSystem.B.dylib from Build Settings --> Linking --> Other Linker Flags

4. Also removed -weak_library from Build Settings --> Linking --> Other Linker Flags
