Agreed. Btw, when compiled against Qt 5.14, "make xconfig" is currently broken. I'm sending in a few some fixup patches for it. > It should be that this task was done with a command like "kconfig enable > vimc".

There were some efforts to add a SAT solver at the Kernel that could be used for that, but I dunno what's current status. > Twenty years ago it made sense to go through the menus and select things > one by one.

Yeah, that's my feeling too. > I started to hack together some code to create a kconfig program to > enable and disable options. The problem is that all library code > assumes we want to display menus so it was a lot of work and I gave up. :-( Thanks, Mauro _______________________________________________ devel mailing list devel@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
