I currently have KTorrent 2.2.1 installed and it is working fine. I am using KDE3, and tried to install KDE4, but it failed (wanted KTorrent 3.0Beta). Is there a debian version of KTorrent 2.2.4 released? If not, what can I do to properly configure KTorrent 2.2.4?

Thanks,
John

I got a similar error with cmake when trying to compile KTorrent 3.0Beta with KDE3:

It fails with the following output:

You need this or this.

I downloaded the build essential package, which I was lacking, but the *.deb file (for my i386) would not install.

I will try to make the 2.2.4 version again with the build-essential package installed.

The build-essential ./configure failed at this point:

...

Because 2.2.4 is packaged only for „lenny” and uses packages in version not availible in your debian release (which, I assume, is older than lenny — etch maybe?).

You need at least these things.

Maybe you should try ubuntu?

KTorrent 2.2.4 for etch is available at:

http://alioth.debian.org/~modax-guest/ktorrent-etch/

I didn't bother to update it for 2.2.5 but maybe I'll do this later. If you want 3.0, you need kde4libs which is available in unstable and lenny. Packaged ktorrent 3.0rc1+ is available in experimental as of yesterday but you will need to upgrade to unstable (sticking with lenny currently might not be sufficient but rebuilding should solve installability problem if you badly want ktorrent 3.0) to install it. There is never going to be a backport of ktorrent 3.0 to etch. It wouldn't be possible without backporting tons of other stuff and therefore it's not worth the effort!

I never said I was using Debian. I am actually using the latest version of Ubuntu. There is no greater version of KTorrent than 2.2.1 in the Ubuntu repositories. KDE4 just became available in the official Ubuntu repositories. I will see if installing those packages helps me build either 2.2.5 or 3.0 from source. Are any of these versions out for Ubuntu in *.deb packages?

KDE4 didn't help. Of course reinstalling the required dependencies didn't help because they are the same dependencies for the KTorrent version in the Ubuntu repository: 2.2.1. I still get this error when trying to ./configure KTorrent 2.2.5:

checking for X... configure: error: Can't find X libraries. Please check your installation and add the correct paths!

I reinstalled the required X library on http://packages.debian.org/source/lenny/ktorrent and still no luck.

If you're using Ubuntu, why are you installing packages from Debian? Don't do this, you'll eventually break your system.

Why would anyone want to install debian packages if he's not using debian?

If you still want to compile you need install these things.

Or, if you want to install packages like real h4xor , add gutsy backports repo, get pkgs list from it, and then install in ubuntu way (apt-get or synaptic or whatever).
