First of all, thank you for your great help. It has resolved almost all of the errors. However, i still get unresolved references to some (not all!) of my references to functions of the pbc library.
These are the errors: smtp_proto.o: In function `scan_element': /usr/local/src/postfix-2.6.11/src/smtp/ibs_sign.c:24: undefined reference to `pbc_malloc' /usr/local/src/postfix-2.6.11/src/smtp/ibs_sign.c:31: undefined reference to `pbc_free' smtp_proto.o: In function `sign': /usr/local/src/postfix-2.6.11/src/smtp/ibs_sign.c:84: undefined reference to `pairing_init_set_buf' /usr/local/src/postfix-2.6.11/src/smtp/ibs_sign.c:95: undefined reference to `ib_sys_param_scan' /usr/local/src/postfix-2.6.11/src/smtp/ibs_sign.c:106: undefined reference to `pbc_malloc' /usr/local/src/postfix-2.6.11/src/smtp/ibs_sign.c:106: undefined reference to `cc_signature_length' /usr/local/src/postfix-2.6.11/src/smtp/ibs_sign.c:109: undefined reference to `cc_sign' This looks strange to me because some calls functions in the pbc library cause no errors. For example a snippet from my code: pairing_init_set_buf(pairing, param, count); ib_sys_param_init(sysparam, pairing); The reference to pairing_init_set_buf() is line 84 from the error message. The next line calls a function from pbc as well, but does not cause an error. Have you got an idea how to resolve this issue? Or do think this is caused on libpbc's side? Again, thanks a lot for your help.
