Hi everyone, I'm using CentOS v4.3 (a RHEL 4 clone) and I can't get ktorrent 2.0.3 to compile correctly.

uname -a = 2.6.9-34.0.2.ELsmp #1 SMP Fri Jul 7 19:52:49 CDT 2006 i686 i686 i386 GNU/Linux

qt = 3.3.3-10.RHEL4

Here is the relevant output from the make command:

Can someone please help? I really love ktorrent, but I also need to run CentOS/RHEL.

It complains about KTabWidget...
You're using a bit older Qt version, what about KDE?
Any chances you could upgrade your KDE to the latest (>= KDE 3.5)?

Unfortunately CentOS v4.3 only comes with KDE 3.3.1, and the most recent update (v4.4) does not change that. This is tied directly to Redhat, and which versions they choose to support for their enterprise customers.
http://www.centos.org/docs/4/html/relea ... U4-en.html

Is there a workaround that would allow me to use ktorrent with the older versions of KDE and QT?

I'm not sure...
If it's even possible to compile with those versions (which I'm not sure), maybe you can find someone who can provide you binary package (centOS forums or something?).

Considering that log you've posted, I don't think I can help you much...

It's surprising there aren't more people having the same issue considering RHEL has such a large user population. I guess they just use other torrent programs..

I searched for someone with a CentOS package for ktorrent, but no one seems to have one. I tried rebuilding a source RPM, but that doesn't work either (errors).

How can I get in touch with the ktorrent developers?

http://apt.kde-redhat.org/apt/kde-redha ... t/kde.repo

Try that, it should help you

Thanks, I just found that today. I'm in the process of having yum upgrade me via the KDE packaging project.

Here are the steps
1. rpm --import http://kde-redhat.sourceforge.net/gpg-p ... a-3e1ab2ca
2. Download http://apt.kde-redhat.org/apt/kde-redha ... t/kde.repo and drop it in /etc/yum.repos.d/
3. yum update qt kdelibs kdebase
4. reboot
5. http://dag.wieers.com/packages/ktorrent/

I'll let everyone know if it works..

it works!

Hopefully the upgraded components won't compromise the stability of my server. Time will tell..
