How to compile the PAM module

[qin]

I compiled with -lc:

$ gcc -fPIC -lc pam_module.c -lpam -lpam_misc -lpamc
$ ld -x --shared -o pam_module.so pam_module.o

and found some functions are not found.

...
....:pam_module.c:undefined reference to '_set_ctrl'
...: pam_module.c:undefined reference to 'pam_syslog'

I have linked the libpam.so, libpamc.so and lpam_misc.so, why it can
not found the missing functions?
