When I installed Fedora Core 8 I configured my desktop for gnome. Now when trying to build an application, it has a dependency on KDE. How do I now install KDE and will it replace my gnome desktop if I install it?

Hello and welcome to LQ!

Yes, both KDE and Gnome can be installed and you could have done that during the original installation. However, if you just trying to install a KDE app in Gnome, you can still do that with yum. Yum will usually take care of all the dependencies you need. I run gnome on a couple of distros and have a number of KDE apps running from gnome. What app are you trying to install?

My new boss uses Taskjuggler for all his department project plans. I am new to Linux and this project planning application. He took me to download the latest source and build it on my system. I did a ./configure and found that it depended on KDE.

You can get "taskjuggler" from the Fedora repo, open a terminal and as root:
all dependencies will be cared for.

The problem with that is I was told our plan used a new feature in the latest version of Taskjuggler and that Fedora had probably not picked it up yet so I should build from the taskjuggler latest sources. This is my first time to build a downloaded source of an open source project. I thought it would be a good learning exercise. It is and I am finding out how much I don't know.

With Fedora if you really need (I would check what version is in the repo first) to compile you almost always need the -devel versions of things (in the repo). In this case I would suspect that you need the kdebase-devel package but you may need others. Pretty much whatever the dependencies that are listed in the readme grab the -devel version from the repo. You may also want to download the source rpm for your app from Fedora's repo (even if it is older than what you want) just to look at the spec file. It will often contain little tricks necessary to get a certain app running happily.

Hello:
In fact the system Provide "add softwore" itself in the start.So you can add KDE in there,I think it will be more easy to understand.When you installed ,you can use GONE or KDE by yourself.

Thanks everyone. I learned a lot on this first LQ session. The ./configure message was a confusing to me because I did not realize it was really wanting -devel for both qt and kde. After installing kdebase-devel which also installed qt3.3-devel and setting the path for the libraries and include files correcting to these directories all the dependencies were resolved. Luckily with the dependencies resolved the make and install went flawlessly. I am one happy newbie!
