Ok, I'll go step by step now :) There are two kinds of symbols in dl modules that need version info, so they get linked properly. 1) the defined symbols, for the modules functions, etc like this one: 00005f60 g DO .data 000000fc Base xml_functions 2) the external symbols which are defined in libphp4.so like this one: 00000000 D *UND* 00000000 php_error If I link xml.so with libphp4.so, then php_error gets a version, but xml_functions does not: 00005fc0 g DO .data 000000fc Base xml_functions 00000000 DF *UND* 00000396 PHP4 php_error If I link xml.so without libphp4.so but with the global: * version script then the opposite happens: 00005fc0 g DO .data 000000fc PHP4 xml_functions 00000000 D *UND* 00000000 php_error So xml.so needs to be both linked against libphp4.so and it also needs to have a version script, so we see the following: 00006020 g DO .data 000000fc PHP4 xml_functions 00000000 DF *UND* 00000396 PHP4 php_error Greg
