PIC implies PIE ;) > Moreover PIC is more suitable for libraries, so it should be the right > choice here. The problem is that applications linked against Qt also need PIC, not PIE. The pkg-config stuff gets this right, but the continued insisting that -specs= stuff should be used to enable PIE on some architectures due to disagreements between dpkg and gcc maintainers causes PIE, if enabled in hardening, to be added too late on the compiler command line (and not ignored if PIC was already given). bye, //mirabilos -- tarent solutions GmbH Rochusstraße 2-4, D-53123 Bonn • http://www.tarent.de/ Tel: +49 228 54881-393 • Fax: +49 228 54881-235 HRB 5168 (AG Bonn) • USt-ID (VAT): DE122264941 Geschäftsführer: Dr. Stefan Barth, Kai Ebenrett, Boris Esser, Alexander Steeg ********** Mit der tarent Academy bieten wir auch Trainings und Schulungen in den Bereichen Softwareentwicklung, Agiles Arbeiten und Zukunftstechnologien an.
