So long as the GLib you built is the same version as the system's or newer, that LD_LIBRARY_PATH should suffice for *running* the code, which is what matters. Just make sure you're using a shell that expands ~ after =. As a rule of thumb, if the character before ~ isn't a space, write $HOME. -- Thiago Macieira - thiago.macieira (AT) intel.com Cloud Software Architect - Intel DCAI Cloud Engineering ___ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest
