    Hi,

    They're definitely in the right place. The project was pulled down from a working copy out of SVN. The only thing I can think of is that clang isn't looking in the directory that I'm telling it to.

    @ls -lh /usr/lib/libabcs*
    -rwxr-xr-x 1 root wheel 246K 26 Dec 22:25 /usr/lib/libabcsCore.1.0.0.dylib

      The command line looks fine to me. Can you try with a minimal project that uses libabcsCore ?

        Just tried building an application via the Creator wizard. An app with a single QWidget. Once I add
        @LIBS += -L/usr/lib -labcsCore@
        to the project file I get the same error as before.

              I just realized, is it me or is -L/usr/lib missing from your linker line ?

                I think it might be you. ;-)

                  Did you try to link to your library by hand on the command line ?

                    You mean run the same command from the terminal? Yes, I get the same error.

                    Given the same code is compiling under Linux and Windows without issue, I'm inclined the think it's a bug in Qt/clang++.

                      No sorry, I meant create a dummy main using a function of your library and call clang by hand to compile/link to see it still has the same problem
