linking an extension against a static archive

Hi I have a problem :). I've got 3rd party libraries to which I do not have the sources, the shared and static versions. Unfortunately, when I link against the shared versions of the 3rd party library, PHP behaves unpredictably (segfaults as standalone version, fails to respond as Apache module). When I link against the static version when compiling the CGI version of PHP, it works without a problem. What I've not managed to determine, is how to link statically when I compile the DSO version. This is the libtool error I get: libtool: link: cannot build libtool library `libphp4.la' from non-libtool objects: /usr/tibco/tibrv/lib/libtibrv.a Any ideas? Please CC me on replies, as I'm not subscribed to the list. Many thanks, Leon. -- System Administrator, Devco : http://www.devco.net Office : +27-21-415-2100
