I have diffed the output from 'configure --help' of the directfb package
from the old version (1.4.17) to the new version (1.6.3).

There are one option removed and a few new are appended.

This option is now not living anymore.

The following options ([auto])are new.
> --enable-sysfs          build with sysfs support [default=auto]
> --enable-mesa           build with Mesa support [default=auto]

And thees options are [default=yes].

And at last one option with [default=no].

I'm not already getting the logic inside the directfb.mk so how to
handle thees different options in the future? I mean, what's the point
to implement a configure option or not? I know some options are platform
specific and for me it is particularly implemented.

For example, there are configure options for jpeg, gif and png support
but not for freetype (all this configure options are [default=yes]) and
freetype is also explicitly set per default in the DIRECTFB_CONF_OPT
with '--enable-freetype'.

Why are the options for the gfxdrivers and inputlist are not complete
filled in the Config.in and directfb.mk file?
In the directfb.mk file is a check for BR2_PACKAGE_DIRECTFB_CYBER5K but
the Config.in file has no option for this. Forgotten?

I can try to rework this two files, but to save unneeded work any help
is appreciated. Can someone point me to the right direction?

Carsten
