Problems installing KDevelop and Qt on Scientific Linux


I'm working with a large amount of C++ code and think I need an IDE to help me debug this. However, I don't have much experience with Linux and Unix. My Scientific Linux machine already has Qt Designer (not 'Creator'), Eclipse and KDevelop. I heard Eclipse is very hard to configure especially for those like me inexperienced with Unix

I am trying to install a newer version of KDevelop, but I need to uninstall the previous version first. How do I uninstall programs in Scientific Linux?

As for Qt, when I tried to install a newer one, I got the message
Code:
error during installation process qt.54.gcc_64 execution failed unexpected exit code: 1

what version of ScientificLinux???
7.0
or the more stable and bit older 6.6

ALL!!! of the code i use is for RHEL6 and NONE has been or will soon be ported to 7

i do not expect to be using 7 for about 4 years yet



qt5 WILL have major problems on SL6
some issues likely with sl7

now there is ( or was) a repo for the NEW kde and NEW qt
but it is experimental and i have not used it

the same way you install a rpm

yum install firefox

---- or ---

yum uninstall firefox

( IMPORTANT !!!!!  SAY NO!!!!!!!!!!!!!!!!! to that challenge !!!!!!!!!!!!!! 
-- do not uninstall "firefox" , 50 other programs will also want to be removed ) 


--- for help see the HELP page

yum --help

--- or the manual page ----

man yum

... don't know the password for root ...
No chance. You simply have no permissions to delete files in /usr/.
Administrator rights are required.
