I had some trouble getting everything to work properly with the new release and Intrepid so I thought I'd share a "how-to" step-by-step for any other noobs in the audience.

1. open a terminal

2.

Code: Select all

sudo apt-get install ktorrent

(this step is only necessary if you run gnome instead of kde4. It will install all the pretty icons and make sure it looks right when running under gnome)

3.

Code: Select all

sudo apt-get install build-essential

4.

Code: Select all

sudo apt-get install automake

5.

Code: Select all

sudo apt-get build-dep ktorrent

6.

Code: Select all

sudo apt-get install libboost-dev

7.

Code: Select all

sudo aptitude install kdepimlibs5-dev

8.

Code: Select all

sudo apt-get install libgmp3-dev

9.

Code: Select all

sudo apt-get install libqca2-dev

10.

Code: Select all

sudo gedit /usr/share/kde4/apps/cmake/modules/KDELibsDependenciesInternal.cmake

(replace 'gedit' with your text editor- kate, etc)

11. **NOTE** This step is likely not needed anymore as the bug has been fixed in recent releases of kde4.2+)

change:
SET("solid_LIB_DEPENDS" "general;/usr/lib/libQtCore.so;general;/usr/lib/libQtDBus.so;general;/usr/lib/libQtXml.so;general;/usr/lib/libQtGui.so;general;/build/buildd/kde4libs-4.1.2/obj-i486-linux-gnu/lib/libkdecore.so;")

to:
SET("solid_LIB_DEPENDS" "general;/usr/lib/libQtCore.so;general;/usr/lib/libQtDBus.so;general;/usr/lib/libQtXml.so;general;/usr/lib/libQtGui.so;general;/usr/lib/libkdecore.so;")


change:
SET("solid_LIB_DEPENDS" "/usr/lib/libQtCore.so;/usr/lib/libQtDBus.so;/usr/lib/libQtXml.so;/usr/lib/libQtGui.so;/build/buildd/kde4libs-4.1.2/obj-i486-linux-gnu/lib/libkdecore.so;")

to:
SET("solid_LIB_DEPENDS" "/usr/lib/libQtCore.so;/usr/lib/libQtDBus.so;/usr/lib/libQtXml.so;/usr/lib/libQtGui.so;/usr/lib/libQtGui.so;general;/usr/lib/libkdecore.so;")

(see this post about the bug dealt with by the above changes if your curious about it)

12. download and extract the source to your home folder.

13.

Code: Select all

cd ktorrent-3.2beta1

14.

Code: Select all

mkdir build

15.

Code: Select all

cd build

16.

Code: Select all

cmake -DCMAKE_INSTALL_PREFIX=$(kde4-config --prefix) ..

**note** if you get the following error:

Code: Select all

CMake Error at /usr/share/kde4/apps/cmake/modules/FindMsgfmt.cmake:22 (message):
 Could NOT find msgfmt program

it can be remedied by entering

Code: Select all

 sudo apt-get install gettext

and running step 15 again.
17.

Code: Select all

make -j4

18.

Code: Select all

sudo make install

**note**

to get rid of the annoying "kwallet launcher" and "httpcachecleaner" popups: create a file called "klaunchrc" with the following text:

[FeedbackStyle]
TaskbarButton=false

and move it to: ~/.kde/share/config/klaunchrc
(thanks to the poster here, I modified their suggestions to fit with this tutorial)

Thank you for providing this detail, I thought I was going mad trying to get v3.x.x working.

Could this topic be made a sticky?

No problem, it's obviously a bit more involved than usual (mostly due to things on Intrepid's side) so I thought that sharing in the pain would be nice.

I absolutely love this software and would hate for anyone not to use it simply because they had a hard time compiling it.

Plus, I am absolutely worthless with code so I felt I should contribute about the only way I can.

Just because Ubuntu ships with broken kdelibs5-dev, the topic does not need to become sticky in KTorrent forum.

So Ubuntu has a problem, therefore Ktorrent has a problem, which means people will go elsewhere or just give up, which seems rather sad.

Following your logic maybe the following should be removed from the download page:

"People on Mac OS X who have trouble compiling should try the following:

configure --prefix=/sw
sed -i -e 's/^whole_archive_flag_spec=.*/whole_archive_flag_spec=""/g;'
libtool
make
sudo make install

Thanks to Borre Gaup for bringing this to our attention. The problem is also explained here, other software might have the same problem."

Not everyone is a developer or full time linux guru, some are just users and with helpful posts on how to compile applications (irrespective of what is at fault) spreads the knowledge, rather than hammering search engines not getting any answers.

Not as worthless as me Thanks again.

If Ubuntu has a problem, report it to them so they actually fix it but do not blame ktorrent for that. It is fine that you come for help. But some steps in that tutorial are to workaround ubuntu brokeness and might confuse users of other distros. Therefore, in my opinion, making this one a sticky would confuse people using other distros even more.

I never blamed Ktorrent, merely looking for a solution that would get Ktorrent working.

Edited:
As pointed out above this is a known bug with Ubuntu - https://bugs.launchpad.net/ubuntu/+sour ... bug/299164 and proposed to be fixed in KDE 4.1.3

I followed this procedure but unfortunately one of the commands fails.

Anyone have any suggestions what I'm doing wrong or how I can fix this?
Its a shame no-one has set a PPA repository for the development builds.

aptitude install kdepimlibs5-dev

Right, sorry about that, updated the steps in the first post.

I followed these instructions to the letter. I get the following error:

I've googled for the GMP problem to see if it's a generic thing but couldn't find anything useful.

Anyone help? Need to upgrade from 3.1.2 because ktorrent just keeps closing down unexpectedly. I leave it on overnight then it's gone without trace!

You probably need something along the line of libgmp3-dev. This package is needed for the country flags.

No actually gmp is to do big number arithmetic, which is used for encryption.

stoeptegel wrote:You probably need something along the line of libgmp3-dev.

Yes, I did. I also had to install libqca2-dev.

Now I have new ktorrent fully working and it appears to be speeding along without any significant problems so far, touch wood!
