If it has rpath set then you should fix that. Otherwise it's not clear if the problem really exists as your example is artificial and doesn't show real things. > The question is, how to get hello linked to /usr/lib/libsharedlib.so, > since in fact that lib is located at $(CUDIR)/../lib/libsharedlib.so? There is no such thing. SONAMEs, not paths, are added to DT_NEEDED. If you mean rpath that's another question and it depends on your build system, among other things. -- WBR, wRAR
