Linking to a dynamic library on a Mac with full path

Question

I am linking a (Python extension) library that embeds the Matlab engine with the following command (generated using cmake)

c++ -mmacosx-version-min=10.6 -bun         


        

Answer 1

Look into the -rpath option to the ld command to control this. You might also be interested in the contents of https://github.com/bimargulies/jni-origin-testbed, which is a demonstration of some relevant technology.

The critical technique here is:

install_name_tool -change libsl2.so "@loader_path/libsl2.so" libsl1.so
