Tribler on Fedora 17

[scrapbrain]

Hi everyone, I am not sure if this should be posted here or in package section or maybe in software section.

I am searching a way for installing Tribler, a decentralized open source bittorent client, in Fedora 17 x86_64. Surprisingly I am not able to find a complete howto anywhere...

I only found an rpm from a third part repository which gives some errors during execution. I cannot find informations about compiling it from scratch: I am missing some basical information on how to grab code from their svn (I am a newbie: I usually get tarballs of the code, then I decompress and compile...).

I also tried an installation through wine which unfortunately crashes randomly when running the application. I was wondering if someone succeded... Have you got some information about installing Tribler?

Secondly: in your opinion, is there a chance that Tribler will ever be included in future Fedora releases?

The issue is Elliptical Curve Cryptography, which is required by tribler, but which has been judged patent-encumbered by the Red Hat legal department. You can try enabling ECC support: https://www.martineve.com/2011/07/22...hy-in-openssh/

Never say never, but at this point, I wouldn't put money on that happening.

Maybe something like openssl-freeworld will appear in the rpmfusion repos.

I see... I didn't know about patents!
In the meanwhile I will gather more information and I will keep trying to compile!
Thank you!

Have you been to this page ? Supposedly, you can install the repo then just do "yum install tribler" for F17.

I did try that rpm. Installed okay and put a menu in 'Internet', but running it that way only produced a lot of cpu and disk activity and no gui in openbox. Running from a terminal gave the 'no EC' error.

Given tribler's purpose and the unknown provenance of the rpm I uninstalled it quickly.

You don't need to enable the repo - just download the rpm and select to install it.

Yes, I tried that.
I added that repo and installed that version of tribler through yum: I think I am missing something because when I run the program I get these errors:

 Traceback (most recent call last):
  File "Tribler/Main/tribler.py", line 27, in <module>
    from Tribler.Main.vwxGUI.MainFrame import FileDropTarget

    _curves = {u"very-low":M2Crypto.EC.NID_sect163k1,
AttributeError: 'module' object has no attribute 'EC'

I don't know exactly what I am missing but maybe it is related with ECC, as sonoran suggested... and I quickly uninstalled too...

[PabloTwo]

Looks like it goes back to the "crypto" (Requires m2crypto) thing.

.......
from crypto import ec_from_private_bin, ec_from_public_bin, ec_to_public_bin, ec_signature_length, ec_verify, ec_sign
.....
AttributeError: 'module' object has no attribute 'EC'

My thinking was that installing from that repo would pull in the needed deps.

Agreed, misbehaving code from an unknown/untested third party repo is always a somewhat scary thing

[sonoran]

As Dr.Eve said at https://www.martineve.com/2011/07/22...hy-in-openssh/, Fedora's /usr/include/openssl/ecdsa.h header file is missing.

You would have to compile openssl with ECC support turned on, as well as incorporating any other changes Fedora makes to upstream openssl, before tribler would run on F17.

With so many other torrent clients available I think I would wait until all the trackers are shut down - and at that point tribler will probably be very popular.

[scrapbrain]

I see... Maybe I will be lucky and tribler will be included in the future in rpmfusion repositories: I added it in a wishlist. When I have some time (in some day I hope) I will try to compile and install m2crypto and all the needed dependencies, then I will try to fetch the code from tribler site and compile everything (before that I have to understand how SVN works). In the meantime all suggestions are welcome

Again, thank you all!

svn isn't very complicated actually. You need the rpm package suibversion installed.
There should be some instructions on the website that you want to "checkout" the code.
Here's an example of one that I use to build rpms for moc (Music On Console).
I have a directory ~/src/ that I use for all my source code compiling in.

mkdir ~/src/moc
cd src/moc
svn co svn://daper.net/moc/trunk

That creates the directory ~/src/moc/trunk/, with all the sourecode in the .../trunk/ directory and sub-directories. You should be able to find the correct command and url from whatever sourcecode website you're trying to get that uses svn.

When code/files are updated, then all you need to do to get the latest is:

cd src/moc/trunk
svn up

..and all changed files since your "co" checkout or last 'up" update are downloaded.
