An exception cannot restrict the rights. Both expand: both are granting you the right to distribute binaries that incorporate a certain amount of code from Qt into the binary. That is necessary due to the nature of inline and template functions -- most C++-based projects carry an LGPL exception like that. In any case, the one in the source code is the valid one. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Development mailing list [email protected] http://lists.qt-project.org/mailman/listinfo/development
