Hi, AFAIK, Module.sysmvers work only with the latest linux kernels (2.6.16 or higher) and not for 2.4 kernel. So still the only option for the 2.4 kernel is kbuild system but that is also not possible in every case.

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.
