Hi
Directfb and sdl are having use flags for each other and enbling them creates a circular dependency.
So if someone wants directfb support in sdl and sdl support in directfb how to do this?

Thnx

Sry, should have put tat there in the first place here it is
Code:
Gentoo / # emerge -pv DirectFB libsdl

These are the packages that would be merged, in order:

Calculating dependencies... done!

!!! Note that circular dependencies can often be avoided by temporarily
!!! disabling USE flags that trigger optional dependencies.

K, difficult to tell 4me, cause i already have emerged both since long.

what gives
Code:

USE="-directfb" emerge -pv libsdl

would that work? emerge.
we will see what happens later on then.

Yea if i disable either dirctfb use flag in sdl
sdl use flsg in directfb then its working.
but the whole point is if the use flags r given then tat means to have support for it it has to be enabled
So if someone wants sdl support in directfb and
directfb support in sdl
then wat to do?
May a bug has to be filed, i am not sure though about it!!

Moved from Portage & Programming to Duplicate Threads, the same problem is discussed in topic "Problem with emerge -avNDu".
