Question

Thats my error:

dyld: Library not loaded: /usr/local/lib/libofa.0.dylib
Referenced from: /sers/david/Projekte/Test/build/Debug/Test.app/Contents/MacOS/Test
Reason: image not found

I’ve done some research and changed the path inside the dylib with install_name_tool:

davids-macbook:Test david$ otool -L libofa.0.0.0.dylib 
libofa.0.0.0.dylib:
@executable_path/../Frameworks/libofa.0.0.0.dylib (compatibility version 1.0.0, current version 1.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.2.1)
/System/Library/Frameworks/Accelerate.framework/Versions/A/Accelerate (compatibility version 1.0.0, current version 4.0.0)
/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.9.0)

But Xcode keeps searching for it in /usr/lib/:

build/Debug/Test.app/Contents/MacOS/Test:
/System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa (compatibility version 1.0.0, current version 15.0.0)

Is there a way to set this in Xcode??? Thanks

Edit: The library is not a Xcode project. Its build with ./configure; make

Answer 1

Normally what I do is this:

1. Set the Installation Directory of the library to @rpath. This will set the install name to @rpath/libofa.0.0.0.dylib. If you’re building the library yourself, you can set this in Xcode; otherwise, use install_name_tool to change it.
2. Set the Runpath Search Paths of the application using the library to the location of the directory containing the library. For example, if you put the library in the app’s Frameworks directory, you’d set Runpath Search Paths to @executable_path/../Frameworks (or @loader_path/../Frameworks).
