Hi all, this is my first post here. I'll start by saying it's a great site, I've found much useful information here but I am now stumped so ask for your help.

I'm having problems installing QT at the moment. I checked the Trolltech website and found a doc which says the reason I can't build QT is because I'm missing the X11 development libraries.
I'm running FC2 so I go the Add or Remove Applications app and check the X Software Development box, then click Update. It then brings up a dialog saying:

"Packages Not Found. The following packages could not be found on your system. Installation cannot continue until they are installed:

Unlocatable package Required by

xorg-x11-libs ('xorg-x11', '6.7.0', '5')
xorg-x11-libs ('xorg-x11-xfs', '6.7.0', '5')
xorg-x11-libs ('xorg-x11-twm', '6.7.0', '5')"

So I go to the command line and run:

rpm -q xorg-x11-libs

which returns:

xorg-x11-libs-6.7.0-5

...which suggests the required package IS installed. Any ideas what is going on or how I could get around this? Obviously I can't remove the package and re-install. I can't upgrade it as it is the latest. I'm puzzled (but also a bit of a Linux n00b).

TIA,

Chris.

You need x11-devel package

Yeah that did the trick. Thanks a lot.

Same problem on my side of the world and when I tried to install the x11-devel pkg it still gave me the unlocatable package error. What worked for me was the following command:
$ rpm -ivh --force path/to/xorg-x11-libs-6.x.x-xx.$ARCH.rpm
Only after that did I have success with installing xorg-x11-devel.
(Just my extra input)
