Can anybody tell how can I specify where to objs > for module-a are. So that it will not complain at link time. The compilation of module-A should generation a file called Module.symvers. Copy it to the directory of module-B before compiling it. See http://lxr.free-electrons.com/source/Documentation/kbuild/modules.txt#484. It gives the explanation, and another solution than the one I proposed above.
