os x linking issue with extension

(I'm not sure if extension development belongs on this list, but I couldn't find a better one. If there is a more appropriate list, could someone please point me to it?) I am working on an extension that is os x specific & relies on Carbon & ApplicationServices (it is a port of appscript, to allow writing applescript applications in php). I used ext_skel to create an extension, and ran phpize. In the config.m4, I put: PHP_ADD_FRAMEWORK(Carbon) PHP_ADD_INCLUDE("/Developer/Headers/FlatCarbon") but when I attempt to use carbon api I get an undefined symbol error from the dynamic linker. looking at the configure script generated by phpize, it seemed to me that the PHP_ADD_FRAMEWORK macro is not actually being used to affect the build. I attempted to change this by manually editing the configure script to add $PHP_FRAMEWORKS to the arguments passed to linktool mode=link, and added PHP_VAR_SUBST="$PHP_FRAMEWORKS". Using make --debug, I verified that linktool mode=link was now being called with the -framework param, but I still get the same undefined symbol error. I don't know much about how the dynamic linker works. What do I need to do to have extension .so link to carbon? I am using the 5.0.3 release source package of php, os x 10.3.8, gcc 3.3 Michael Johnston
