Hi All, I want to know how to link object files (.o) to a static library (.a) and generate Loadable Kernel Module. Any pointers to examples demonstrating this should be of great help. Here is what I do now. I have three source files say x.c, y.c and z.c I compile x.c to generate static library libx.a using the following command. # ar -r libx.a x.c Now I compile y.c and z.c to generate x.o and y.o # cc -DMODULE -D__KERNEL__ -I/usr/src/linux/include -O2 -c -o y.o y.c # cc -DMODULE -D__KERNEL__ -I/usr/src/linux/include -O2 -c -o z.o z.c Now as the final linking step I do this # ld -r -o lkm.o y.o z.o -lx -L. But when I try to load lkm.o I get unresolved symbol errors for the functions which are in x.c. I guess there is something wrong with linking procedure I use to generate the lkm.o Please help me fix this. Thanks, -Jinu -- Kernelnewbies: Help each other learn about the Linux kernel.
