hello

I managed to install X.org (xterm is displayed after startx), but I am stuck after the statement

Code:
USE="cpu_flags_x86_mmxext" emerge --ask kde-apps/kdebase-meta


here is the error message:

Code:
The following USE changes are necessary to proceed:
 (see "package.use" in the portage(5) man page for more details)
# required by media-libs/phonon-vlc-0.9.0::gentoo

here is my USE part of make.conf:

Code:
USE="bindist alsa usb -gnome -gtk kde Xy
 wayland -bluetooth cpu_flags_x86_mmxext -qt4"


if I remove "-qt4" the above statement produces an error telling me qt5 is needed.

so I add qt5 in USE and then I get

Code:
The following REQUIRED_USE flag constraints are unsatisfied:
    qt4? ( !qt5 ) qt5? ( !qt4 )


thanks

somes packages remain need the qt4 use flag, so add on make.conf > qt5 and add the packages that need qt4 on package.use


example:

media-sound/pulseaudio qt4
app-text/poppler qt4
dev-util/cmake qt4

Actually, use a plasma profile and you will be served without this use flag mangling.

It's not an error message, it's Portage giving you a copy-paste solution to your update.

PS: You don't install kdebase-meta anymore. Emerge plasma-meta and then a kde-applications meta package (or all of them) of your choice. There is an extensive guide: https://wiki.gentoo.org/wiki/KDE
