How to build PHP4 shared object extensions?

Hello all! I try to build additional extension modules for PHP4 (4.0.5RC6) on Debian Linux 2.2r3 for connecting to commercial databases like Sybase, Oracle8, and IBM DB/2. But all what I get is a big PHP4 module with all additional interfaces linked in (I use APXS from Apache 1.3.19). Can anybody tell me how to build a separate .so PHP module especially for Sybase-CT (this I need most urgently). If you can give me a pointer to an URL or a FAQ, this would be also fine. Thank you very much. Guenter -- Dipl.-Ing. Guenter Millahn Brandenburg University of Technology Systems, Network & DB Admin CS Dept / DB & IS Research Group Voice: +49 (355) 69-2272/2700 P.O.
