The only way that I see to detect OpenGL support in QT is by running the following command: nm -A /usr/local/lib/libqt-mt.so | grep -q updateGL If the exit code is zero, then OpenGL is compiled into QT. Perhaps I can trash the slave port and just run that check in the MythTV Makefile. If OpenGL isn't detected, I can either exit with an error or disable it and proceed. > > >> - - As mentioned previously in this thread, --disable-backend support has >> been removed from MythTV's configure script.
