That's not just Mac. It happens on all platforms. qmake does not add a dependency on the .a file, so the other target doesn't get relinked. > The best way to fix this seems to just include the relevant platform support > .pri files directly in the cocoa plugin (see > http://codereview.qt-project.org/#change,16107).

Those out-of-source plugins would not link properly. The way I see it, our options are: 1) do nothing (not an option, just for comparison) => no plugins link properly => relinking broken 2) add the missing LIBS to platformsupport => plugins link to libs they don't need => relinking broken 3) break platformsupport into smaller libs => lots of work => links properly => relinking still broken 4) remove the libs completely => links properly => relinking fixed => plugins outside of qtbase cannot use platformsupport -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center Intel Sweden AB - Registration Number: 556189-6027 Knarrarnäsgatan 15, 164 40 Kista, Stockholm, Sweden
