@ kakaroto: Thank you for redirecting me to the right post, but I still can't build libnice on Ubuntu Hardy i386 ! Here's the output log:

Let me just say I don't really need farsight, I'm reporting this bug to help your development. If you need other info or help just tell me.

Keep up the good work and thank you again!

[kakaroto]

@muratasenel : I don't understand, aMSN detected farsight and compiled the library, or it didn't ? if it did compile it (and you have utils/farsight/tcl_farsight.so ) and aMSN can't detect farsight in the audio/video assistant... then open amsn's console with ctrl-shift-C and type "package require Farsight".. if it answers with some error copy/paste it here.. if it answers with "0.1", then launch aMSN from an X terminal, and copy/paste the output from the terminal in here...

@Montblanc.. ah sorry, someone reported that already and I answered him here : http://www.amsn-project.net/forums/viewtopic.php?t=5248
to everyone else and to keep all answers in this thread, here's my answer :

ah.. right.. I fixed that but forgot to push my changes to the server (and I can't do it right now since I have less than 2% battery on the laptop, and I forgot the charger at work...).
To fix it, open the file libnice/stun/usages/ice.c and add at the top of the file below to the other include lines :

Code:

   #include <arpa/inet.h>

I hope someone can get this working... I'll see how it works on monday, now I'll be busy this week-end.

[kakaroto]

UPDATE : I pushed the changes to fix the include problem with libnice... and added autogen.sh to libnice... guide updated!
UPDATE2: Changed the git repository URL and changed the branch name to get the latest changes... guide updated!

Hi again...
so here is my experience after trying to test this on a 'virgin' PC... I hope my experience will help others fix any problem they might have...
I was doing all this on a debian/unstable machine, so any ubuntu/other distro users might have a different experience...
First, the easy part... I did a simple 'apt-get update' to update my debian unstable package list, then, at my big surprise, I found that debian had all the LATEST versions of gstreamer available, which is just great! so I did :

Code:

sudo apt-get update
sudo apt-get install libgstreamer0.10-0 gstreamer0.10-plugins-base gstreamer0.10-plugins-good gstreamer0.10-plugins-bad gstreamer0.10-tools gstreamer0.10-alsa

This installed for me gstreamer 0.10.20, gst-plugins-base 0.10.20, gst-plugins-good 0.10.8 and gst-plugins-bad, 0.10.7
Now I wanted to install gstreamer0.10-plugins-farsight, but we need 0.12.9 and they only have 0.12.8.. so here's how I got it to install...

Code:

sudo apt-get install debhelper
sudo apt-get build-dep gstreamer0.10-plugins-farsight
apt-get source gstreamer0.10-plugins-farsight
wget http://farsight.freedesktop.org/releases/gst-plugins-farsight/gst-plugins-farsight-0.12.9.tar.gz
tar -xzvf gst-plugins-farsight-0.12.9.tar.gz
cp -r gst-plugins-farsight-0.12.8/debian gst-plugins-farsight-0.12.9/
cd gst-plugins-farsight-0.12.9/debian
vi changelog

Here, I modified the changelog so that I can get the correct version in the generated deb file...
so I just added at the top of the file :      

Code:

gst-plugins-farsight (0.12.9-1) unstable; urgency=low
  * New upstream release

 -- Youness Alaoui <CENSORED@CENSORED.COM> Sat, 02 Aug 2008 01:53:00 -0500

 

and then ... ":wq" to quit vi, and :

Code:

cd ..
dpkg-buildpackage -rfakeroot
cd ..
sudo dpkg -i gstreamer0.10-plugins-farsight_0.12.9-1_i386.deb

and voila!
most dependencies are installed.. now I just need libnice and farsight...
so I use the commands on the wiki to download them...

Code:

git clone git://git.collabora.co.uk/git/user/kakaroto/nice.git libnice
cd libnice
git checkout origin/nice-kakaroto
cd ..
git clone git://git.collabora.co.uk/git/user/kakaroto/farsight2.git  farsight2
cd farsight2
git checkout origin/nice
cd ..

Then I go to the libnice directory (cd libnice)...and I do :

Code:

./autogen.sh --prefix=/usr
make
sudo make install

(yeah, I didn't do the --prefix=/usr at first, then I realized it was needed otherwise farsight won't find libnice at runtime)
Then I go to the farsight2 directory.. and after some problems with the ./autogen.sh which gave me "automake failed" I found the solution, so :

Code:

sudo apt-get install gtk-doc-tools
./autogen.sh --prefix=/usr --disable-python --disable-gtk-doc
make
sudo make install

yes.. here again, the --prefix=/usr is needed as well as --disable-python otherwise you would need a lot more dependencies (gst-python, etc...) and the 'sudo apt-get install gtk-doc-tools' will allow you to do the ./autogen.sh without the annoying "automake failed" error.. The --disable-gtk-doc is because the gtk doc will currently not build correctly, so use that configure option until it gets fixed.
and now finally.. the most important step otherwise it won't work... you have to do :

Code:

sudo ldconfig

yep.. that might be why muratasenel couldn't make it work (or because of the --prefix=/usr)
Once you do that, in theory, everything should be great!
Now, you go over to amsn.. and you do :

Code:

svn update
./configure
make clean
make
./amsn &

amsn loads.. you press 'sign in' and you should see a lot of output in the terminal with the last three being :

Code:

** (<unknown>:17803): DEBUG: CANDIDATES ARE PREPARED
** (<unknown>:17803): DEBUG: Detach source 0x8fca228 (stream 1).
** (<unknown>:17803): DEBUG: Detach source 0x8fb18a8 (stream 1).

This means all went well...
You could also press Ctrl-N from the main aMSN window to see the audio/video assistant which will test if farsight is correctly installed...

In theory, it should all be working correctly at this point!!!!

If it doesn't.. follow these steps carefully!
1 - read this post
2 - read this post again
3 - Make sure you didn't forget anything... (--prefix=/usr or ldconfig..)
4 - press Ctrl-Shift-C from the main window
5 - type "package require Farsight"
6 - the error should tell you what's wrong, if it's something like "can't find shared library : libgstfarsight.so" it means you either didn't install farsight2 or you forgot 'ldconfig'
7 - if it returned "0.1", then type "farsight Prepare 1"
8 - the error again should tell you what's wrong... if it says "couldn't create fsrtpconference", then you might have forgotten the --prefix=/usr, if it says "can't find nicesrc element", then it means you didn't install libnice correctly (or forgot --prefix=/usr for it), other kind of errors might be because you forgot to install gst-plugins-bad or gst-plugins-farsight, etc...
9 - if it doesn't give any error there, but the audio/video assistant still says that it's not installed.. then the error might be coming from farsight after it's been prepared correctly.. so look at the error messages on your terminal (the xterm terminal, not amsn's console), it should again point you in the right direction as to what you did wrong..
10 - if you get no output at whatever you wrote in amsn's console, then TYPE THE COMMANDS in the console, DO NOT copy/paste them please...
11 - make sure you installed the CORRECT VERSIONS!!!! for example... if you installed gst-plugins-farsight 0.12.8 instead of 0.12.9, IT WILL CRASH...
11 - if you REALLY don't get it.. post here the output of either the "package require Farsight" (5th step) or the "::farsight Prepare 1" (7th step), or the output on the terminal (9th step).. and tell me exactly what you did to get that error message...

That's it...
I think this will serve as a good guide for anyone having trouble with this...
Please note that :
1 - hopefully debian will soon put the gst-plugins-farsight 0.12.9 in their repositories you won't need the 'apt-get source' + 'apt-get build-dep' + 'cp debian' + 'vi changelog' + 'dpkg-buildpackage' + 'dpkg -i' trick to get the 0.12.9 debian file into your system...
2 - hopefully, other distributions will follow in debian's footsteps in order to provide packages from the latest versions of gstreamer, etc...

In theory, when aMSN 0.98 will be released, this whole thing should become as simple as :

Code:

sudo apt-get install libgstfarsight2-dev

p.s.: When farsight2 is working and you test the call... you should see ALOT of output on your X terminal.. something like this :

Code:

** (<unknown>:25932): DEBUG: Agent 0x8f16680 : s1:1: sending 52 bytes to [192.168.1.101]:62878
** (<unknown>:25932): DEBUG: Agent 0x8f16680 : Packet received on local socket 30 from [192.168.1.101]:59636 (80 octets).
STUN error: RTP or other non-protocol packet!

This shows your connection succeeded and that you are sending and receiving data... yeay, great!

NOTE: IF YOU DO NOT USE DEBIAN UNSTABLE, DO NOT BOTHER ME, TRY TO FIGURE THINGS OUT ON YOUR OWN, USING THIS GUIDE AS A REFERENCE!!!!

thanks all!

Hi

In order to get libnice to compile, after I included the line #include <arpa/inet.h> to the libnice/stun/usages/ice.c file, it crashes again.
Now I had to open the file libnice/agent/conncheck.c and change the line 472 from agent, p, buf_len); to agent, p, (int)buf_len);
It now compiles fine.

Hope this helps someone.
All the best

Dave

aMSN detected farsight and compiled the library tcl_farsight.so but aMSN still can't detect farsight in the audio/video assistant. Then I opened amsn's console with ctrl-shift-C and typed "package require Farsight" and it complained it "can't find package Farsight". Then I opened the audio/video assistant with Ctrl+N and still it can't detect farsight. Below is the output from the terminal:

I can't see anything about farsight here, I hope it helps.
And in your another post, you mentioned that this problem might be occuring because of not doing ldconfig or of not giving --prefix=/usr in configure but I did all of them and still have the problem.
To be honest, I assume something is wrong with my configuration or the way I installed dependencies and aMsn. So, I'm willing to spend my weekend to find out where I did wrong

I didn't encounter the second problem you had but for anyone who uses gcc43, if you get INT_MAX error, add #include <limits.h>
 in file stun/tools/stund.c.
The patch is also here http://svn.pardus.org.tr/pardus/playground/murat/programming/libs/libnice/files/gcc43.patch

[kakaroto]

thanks dave_p_b and muratasenel for the info. I will commit those patches too on git on monday...

[fcastillo]

After trying everything, I can't make it work, I can't build the package of gstreamer farsight plugin. I don't know why things can be a little bit easier, i just going to give up... I really want to use aMSN with voice, that was the only thing stopping me to move completly to linux from windows, but I guess I'll have to get stuck with windows since linux things are too complicated. Thanks for everybodies help by posting this help, but things work different in evey linux distro, so what one did doesn't work in another, but thanks again...

[kakaroto]

@fcastillo, it works the same pretty much everywhere, but this isn't because linux is complicated, it's just because this is in development, and no distribution has the packages..
as I said :

In theory, when aMSN 0.98 will be released, this whole thing should become as simple as :

Code:

sudo apt-get install libgstfarsight2-dev

or actually.. to be more precise, just doing 'apt-get install amsn' and that's it... for any distribution actually you would just need to click on 'amsn' from the install package system interface... (synaptic or whatever on the other distro).
You can try to get it to compile (make sure you have gstreamer -dev packages to compile gst-plugins-farsight) or just be patient and wait for the release.

[Montblanc]

@ kakaroto: Thank you! Everything is fine, now! Sorry about not noticing that post earlier... Keep up the good work!

[kakaroto]

cool! Does that mean that you were able to compile everything and that amsn reported farsight as working, or it means that you tried to make a call with a WLM user and that it succeeded ?

[fcastillo]

I really appriciaty what you do, I think I'll just have to figure out how to use voice calls on MSN, compiling aMSN it's not difficult, only farsight it's the problem. Well, I'll keep trying but for some weird reason farsight doesn't want to be compiled  :cry: I don't know if any of the people in this forum can post the .deb package generated for the gstreamer farsight plugin. After that, the rest it's easier, I don't know why buy my computer doesn't want to generate the .deb package with the necesary version. Ubuntu only hast version number 5, not even 8.

fcastillo, please don't think about giving up. More testers mean better aMSN. So, please just copy whole compiling output of farsight and we will figure out what's wrong. I'm sure it's not a big problem since most of us are able to compile it.

[fcastillo]

it's not farsight itself it the gstreamer farsight plugin.... Since I need it to compile farsight... The plugin is the one that's giving me more trouble... Well, I'll try one more time, later on and I'll post the result as soon as I can... Thanks again, and you're right that if more people test aMSN, it'll be better. I hope you can help me...

[kakaroto]

@fcastillo : just give us the output you get from gst-plugins-farsight when you try to compile it.. as long as you have the necessary dependencies, it should compile without any problems.. so make sure you did the "apt-get build-dep gstreamer0.10-plugins-farsight" if you are on a debian-based distro (ubuntu ?). You can also tell us which distro you are using, it might help us tell you which commands to execute.

@everyone else: I updated libnice with some changes that should make it easier for you to compile (autogen.sh added, and fixed the include problem). It should also fix some issues that we were able to find with muratasenel, where it didn't work with people not on the same local network (that's the only thing I tested.. lol). We still have problems with people on asymetric NATs, and I'm still reverse engineering the issue with peer-reflexive candidates... although I finished reverse engineering it, and it should now work correctly... it appears to still not want to work.. more investigation that way...
