What needs to dlopen openblas, etc? dlopen returns a value and needs to be saved does it not? If dlopen occurs on a library that is already loaded, it doesn't error, but does it succeed in the way that Julia expects it to? Or are you saying that openblas, etc just needs to be loaded somehow and then it all works out, my library can invoke dlopen brute-force like with maybe an arbitrary location. on these things?
To be honest, I don't quite understand why this is even happening except for possibly side effects of resolving symbols at link time. After all libopenblas and libdSFMT are in the same exact directory as libjulia, and libjulia does get loaded no problem. Hmm @loader_path is a value eh? I don't see that documented. -Jeff
