modules/embedded function and Mac OSX

I've been having some problems building some modules or embedding the function in PHP. I've attempted to build several different modules and all give the same results. If I build as a module, placing an 'extension=' entry in php.ini causes a dylib error. dyld: /usr/sbin/httpd Undefined symbols: __array_init __convert_to_string __efree __emalloc __estrdup __estrndup _add_assoc_long_ex _add_next_index_double _add_next_index_string _convert_to_array _convert_to_long _________________________________________________________________________ Without the 'extension=' entry in php.ini, placing an entry in my php script "dl('module.so');" results in the following log entry: [Fri Feb 4 06:12:38 2005] [error] PHP Warning: module: Unable to register functions, unable to load in Unknown on line 0 _________________________________________________________________________ If I use this entry in my php script, the module functions work properly. if (!function_exists('my_function') && @dl('module.so')) { } _________________________________________________________________________ Is there anything specific I need to do for Mac OSX to build modules or embed them in PHP so they work properly?
