How to compile the PAM module

[qin]

Hi,

It seems that is the stupid question, but I don't find any hints in
docs about the key.

I wrote a PAM module, however I do not know how to compile. I tried the

gcc -shared -o pam_module.so pam_module.o -lwhatever
-I/path/to/pam/module/include

But it do not work.

I have no idea. Could sombody give me some advice?

Thanks
