Try adding -L/usr/local/lib as a linker flag, but be sure to pass it as the first flag as opposed to appending it to the end; if I recall correctly that sometimes matters. -Patrick On Jun 4, 2008, at 3:16 PM, Fabrizio Bertocci wrote: Well, Unfortunately that is not the problem... because the error I get are about some unresolved externals, and not library not found (that is the error you get when the linker can't find the right library). Interesting enough, when I try with a small library (typical hello world-style), everything works, but not with the xmlrpc-c library... I will continue investigating this issue...

To be more specific, this is *NOT* working: ld <...> -lxmlrpc++ -lxmlrpc_server_abyss++ -lxmlrpc_server++ -lxmlrpc_server_abyss -lxmlrpc_server -lxmlrpc_abyss -lxmlrpc_util -lxmlrpc_xmlparse -lxmlrpc_xmltok -lxmlrpc and this IS WORKING: -lxmlrpc++ -lxmlrpc_server_abyss++ -lxmlrpc_server++ -lxmlrpc_server_abyss -lxmlrpc_server -lxmlrpc_abyss -lxmlrpc_util -lxmlrpc_xmlparse -lxmlrpc_xmltok /usr/local/lib/libxmlrpc.a Weird isn't it? Am I missing something? Is it really a bug ? Thanks for your opinion. Fab _______________________________________________ Do not post admin requests to the list. They will be ignored.

Can you post the Xcode transcript ? It may help us to find what is the problem. To include the transcript, just drag and drop the "Linking xxxx (y errors)" line from the build window to Mail. is /usr/loca/lib in your library search path in Xcode target build settings ? Brief description: I'm building an executable (command-line) that requires some external libraries. Let's say I need to link (statically) with: /usr/local/lib/libfoo.a /usr/local/lib/libbar.a /usr/local/lib/libfoo++.a /usr/local/lib/libbar++.a When I add those libraries to my Xcode project, Xcode end up passing them to the link phase using the -l<lib> form: -lfoo -lbar -lfoo++ -lbar++ Unfortunately, the link phase reports a bunch of unresolved symbols. If I invoke by hand ld by specifying the static libs directly as input files instead of libraries everything works fine: ld ... /usr/local/lib/libfoo.a /usr/locallib/libbar.a /usr/local/lib/libfoo++.a /usr/local/lib/libbar++.a Interested? If you want to reproduce it, download the xmlrpc-c library from Sourceforge (xmlrpc-c.sourceforge.net), build it and install it under /usr/ local and try to build one of the example first using the form that uses the -l<lib> flag, and then with the other form. In my case I also discovered that ONLY ONE library needs to be listed using /usr/local/lib/<blah>.a... _______________________________________________ Do not post admin requests to the list.
