Yes, this does work :-) I found more information at https://www.kernel.org/doc/Documentation/kbuild/modules.txt too Thanks. -- Sankar P http://psankar.blogspot.com ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies

Building multiple .ko files from a single module
Hi, I have some source files: a.c b.c c.c etc. Now I need to generate a few .ko files such as, 1.ko, 2.ko, 3.ko etc. I know the correspondence between the source files and the .ko file. Is there a way I could achieve this with a single Makefile ? All the tutorials and the help pages seem to focus on creating a single .ko file from a Makefile, as that is the usual case. However, I need to have different modules generated from my sources. For some shareability reasons, I cannot move the sources to different folders either. Can someone please show me how it should be done ? For example, consider the following association between source files and the .ko files. a.c a.h common.c common.h => 1.ko b.c b.h common.c common.h => 2.ko Thank you. -- Sankar P http://psankar.blogspot.com ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
