That doesn't work when we're talking about another set of include paths that are not the system's. This can also happen intra-Qt too, if you're doing split builds. Suppose you're building qtmultimedia again but it's already installed. You need to link to qtbase libraries, so the -L for the install dir is provided. That means the old set of libraries may be found. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
