Why are the other -l needed? Given that harminv.h is self-contained you do not need other libraries at link-time because all references can be resolved with libharminv.so, no? And the symbols harminv itself needs do not need to be specified at application link-time because they will be resolved by the runtime linker. A sample program I just came up with linked with -lharminv just fine, too. But maybe you can try it with real programs yourself. (If your program needs the other libraries by itself, i.e. by using symbols of them, it needs to link with them, of course, but that's seperate.) Kind regards, Philipp Kern
