install_name_tool

Documenting commands I used for fixing paths

Starting with:

$ oTool -L libfreenect.dylib

This lists all the other native files and where they are being looked up.

libfreenect.dylib:
	/usr/local/lib/libfreenect.0.5.dylib (compatibility version 0.5.0, current version 0.5.0)
	/usr/local/lib/libusb-1.0.0.dylib (compatibility version 2.0.0, current version 2.0.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)

So now I want to look up libusb-1.0.0.dylib in the same directory as libfreenect.dylib. install_name_tool will take care of this. @loader_path refers to the path where the path where the first native library was loaded.

$ install_name_tool -change /usr/local/lib/libusb-1.0.0.dylib @loaderpath/libusb-1.0.0.dylib libfreenect.dylib

Now it's

libfreenect.dylib:
	/usr/local/lib/libfreenect.0.5.dylib (compatibility version 0.5.0, current version 0.5.0)
	@loader_path/libusb-1.0.0.dylib (compatibility version 2.0.0, current version 2.0.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)

So far nothing is complaining about libfreenect.0.5.dylib or /usr/lib/libSystem.B.dylib so not changing those until I hear of any bugs?
