Mac OSX, where to put the SDL Framework?

SDL Development
1

I just ported a Windows game to OSX.
The APP works, but only on this computer.
Cause: The APP is looking for the framework in \Library\Frameworks.
On a different computer it’s not there and the APP crashes.
How do i link it in a correct way?

Contents/MacOS/YourAppName
Contents/Frameworks/SDL.framework

Thanks for your reply.
The framework is in the APP bundle as you suggested.
Still the framework gets linked from \Library\Frameworks\ on start.

Here’s my project’s structure:

That’s the crash report:

Are you sure the frameworks are getting copied to game.app/Contents/Frameworks/ and not game.app/Contents/Resources/ or some other subfolder? The Copy Files build phase lets you select a specific subfolder that the files are copied to.> On Oct 3, 2015, at 5:56 AM, lakibuk wrote:

I would suggest that you remove the SDL framework from Library/Frameworks/
and move it elsewhere. Set up your linked frameworks again to link and
bundle from the new location. Perhaps then there won’t be implicit linking
with the framework in the default path?

You would need to specify linking paths. On OSX there are several ways to
do this, see here:

Thanks for your hints, it works now.
What i did:
1.) Copy framework to project folder
2.) Add @executable_path/…/Frameworks in Runpath Search Paths
