openssl signature for ida

Hello,

i've just compiled openssl and now when i try to make a signature pcf yells:

pcf libeay32.lib libeay32.pat
Fatal [libeay32.lib] (LIBEAY32.dll): not a coff module
press enter to exit.

does anyone know how could i generate those signature files for ida? i already have the .sigs here that someone else generated but i'd like to know how to do it by myself.

thanks in advace
