If you want only a very basic kmscon program without any major dependencies,
use:
- $ ./configure --disable-debug --with-video=fbdev --disable-multi-seat --with-fonts=8x16 --disable-pciaccess --with-sessions=dummy,terminal
+ $ ./configure --disable-debug --with-video=fbdev --disable-multi-seat --with-fonts=8x16 --with-sessions=dummy,terminal
However, you will loose a lot of functionality by dropping all dependencies.
The following configure options are available. If build-time dependencies
multi-seat support for kmscon. [default: on]
--enable-hotplug: This requires libudev for hotplugging support. This is
currently mandatory and cannot be disabled. [default: on]
- --enable-pciaccess: Enable GPU detection via pciaccess [default: on]
--enable-debug: Enable debug mode/messages [default: on]
--enable-optimizations: Enable code optimizations [default: on]
--enable-eloop-dbus: Build dbus extension for eloop library [default: off]
