Author Topic: [C++/OSX] libraries don't link properly (Read 5921 times)

zhinchliffe · « **on:** January 03, 2009, 12:16:46 am »

I am attempting to build a friend's SFML game on the Mac OS X platform, and am having a bit of trouble. I start a new Xcode project from the Xcode templates included with the SFML download. It builds and runs fine. But then, when I change the main.cpp into the one for my friend's game, the built application will not fully launch. GDB tells me (see bottom of post) the application cannot load the SFML frameworks from the Frameworks directory of the app bundle, and sure enough, no Frameworks (or Resources) directories have been created, even though Xcode says it built properly. What would be the cause of this? I'm not positive if my friend wants me to share the source, but I'm just wondering if there's anything that can be put in main.cpp that'd disable the proper linking of the libraries?

And, furthermore, when I put the libraries manually into the Frameworks folder, it still doesn't load. What's up with that?

The debugger asks for the frameworks to be copied in appname.app/Contents/Frameworks. Make sure this is where you put them.

Otherwise, for general development with SFML, the frameworks must be copied in /Library/Frameworks.

right, but usually the frameworks are automatically put in that folder, and now, for some reason, they are not.

Never has this been done automatically.

If you wish Xcode to do this for you, use a build phase (Xcode Build System Guide).

but when I compile the basic included SFML template, it DOES do it automatically. :?

Not with the latest versions of the templates, because I consider this is rather an advanced step, and therefore is not required for SFML development.

But if you use the old templates... I do not understand why you can't find the frameworks in the <name>.app/Contents/Frameworks directory :? .

Whatever the debugger tells you, if you copy the right frameworks in /Library/Frameworks, you application or executable will work fine.

okay, now when I put the files in there, the application stalls for a bit and crashes.

do you think we could talk about this on an instant messenger so I could get this problem figured out a bit faster? i've listed my contact details below:

What's written in the Xcode's console ?

There is no crash described in this log.
