Re: Copying native library into app bundle and linking from there

[Ivan Vučica]

I think no -- there is probably no built in support as ATM almost all GNUstep 
apps are shipped as source code.

Use @rpath on non-OS X and use @executable_path on OS X as part of the path to 
the library (in Xcode that's the INSTALL_PATH).

Please google around for further reference; this is somewhat complex to get 
right, but is not all THAT difficult.

Even with OS X where this is a common scenario you have to think carefully 
about what you are doing -- the defaults for producing frameworks are not 
optimized for your scenario, but for producing frameworks to be placed in 
/Library/Frameworks (and even then...)

If I'm wrong, someone can correct me
