EXT_SKEL question

Hello Rasmus and Zeev and all the others: Back in March, I attempted to get to the bottom self contained extensions. I never succeeded at doing that, but I was able to get embedded extensions compiled and working. Unfortunately, I lost a hard drive last week and my PHP development environment went crash... No source code lost, just environment. In trying to rebuild my PHP dev environment, I have come across a sticky issue that you guys may be able to help me with. I cannot remember how I solved it last time. I am still using PHP 4.0.4.pl1 (not 4.0.6). After running: /php/ext/EXT_SKEL --extname=addmod, I discover in the ext/ directory another directory named "addmod". This extension compiles as embedded code into libphp4.so using: ../php/configure --with-mysql --with-apxs --with-addmod Now, when I want to add code to addmod.c that would call functions stored in shared library /lib/libwhat.so, I find the compilation process generates "definition" errors for functions that reside with /lib/libwhat.so. The important question is, what file and where within it do I add a reference so that the linker can resolve the unknown definitions that are inside of /lib/libwhat.so or any other shared library for that matter. The syntax you would use to make the unresolved reference go away would be very help as well. Inside the addmod directory, there is addmod.c php_addmod.h, Makefile, Makefile.in and config.m4. It is not clear where I add the reference to allow the linker to know that unresolved references are in /lib/libm.so or other shared libraries Any response appreciated. Mark Diener
