Hi folks.
I am running Gentoo( 2.6.38-gentoo-r6). Recently I have installed aMule (2.2.6) using

Code: [Select]

USE="upnp" emerge amule After installation, I click the aMule item in 'Applications->Internet->aMule', and aMule's GUI shows up. Then I click the close  button, a dialog saying 'Really to exit aMule' pops up, and I click Yes, so the GUI windows is closed. However, when I click the aMule item again, no GUI shows up again. It's so weird. I am quite sure when I close the GUI window for the first time, no amule process is running.
Anyone know the reasons? Thanks in advance.

Something more:
     After closing all amule processes, I type amule in the terminal. It shows

Code: [Select]

Initialising aMule 2.2.6 using wxGTK2 v2.8.11
Checking if there is an instance already running...
No other instance are running.
ListenSocket: OK
HTTP download thread started
And the GUI of amule never display. It stuck there. Any ideas will be appreciated.

Firstly, I have to apologize if it is not proper to post here. And I posted it in the board aMule Help, but no one answers me. So I post it here.
I use the Gentoo(2.6.38-gentoo-r6) and aMule(2.2.6). After installation using USE="upnp" emerge amule, I click the aMule item in 'Applications->Internet->aMule', and aMule's GUI shows up. Then I click the close  button, a dialog saying 'Really to exit aMule' pops up, and I click Yes, so the GUI windows is closed. However, when I click the aMule item or type amule in terminal , no GUI shows up again. It's so weird. I am quite sure after closing the GUI window for the first time, no amule process is running. Here is the backtraces.

Hope make myself clear. Any ideas will be appreciated.

Try deleting (moving/renaming) ~/.aMule/amule.conf

Maybe the window size/position is invalid there.

[GonoszTopi]

Not getting an answer immediately doesn't mean you won't get one. Everyone here does this on their free time, which is sometimes less then we'd like it to be.

Conversation continues on your other topic.

[machinarium]

Thanks for your reply. I tried your suggestion, but it didn't work either. Even I delete the whole directory .aMule, the GUI window just wouldn't display. Is there any body who can use amule 2.2.6 normally under Gentoo?

[GonoszTopi]

Does your aMule log file (~/.aMule/logfile) contain any error/warning/strange thing?

From the backtraces above I posted, it seems to be caused by libc, which is part of package glibc in gentoo. Need to downgrade the version of glibc? This is quite dangerous to the base system of gentoo.

[Stu Redman]

I merged the two topics to avoid further confusion.

Problem is not cause by libc. The app somehow deadlocks in the http download, whatever it tries to download here (maybe new serverlist ?).

Can you try the 2.3.1.rc1 to see if the problem occurs there too?

Sorry for the confusion caused by my impatience, I will try 2.3.1.rc1 and give the experience after installing it.

[machinarium]

Below is my recent attempting. First I reinstall amule 2.2.6 from Gentoo portage. And I type amule in a gnome-terminal, I get the GUI, click off the Check for new version at startup. Now the annoying problem disappears. I can close and open the amule casually. So there is no necessary to try to install amule 2.3.1 RC, sorry for Stu Redman. But I just don't know how the action of checking new version can stick the startup process of amule.

[Stu Redman]

Ah, that was the blocking http download...
It would still be interesting to see if the problem persists wit 2.3.1.rc1 . If yes we have to do something about it before releasing it.

I'm sorry for having not so much time to install 2.3.1.rc1 and test it. These weeks I have a lot of exams such algorithms, software testing and os. Maybe this problem is related to the OS(Gentoo), because I can use amule 2.2.6 normally in Ubuntu 10.04. Or the problem is related with my network conditions. I have two network cards with one to which no cables connect and the other one connecting to the Router(TL WR340G+). And the connected card is configured to use dhcp, getting ip address 192.168.1.100(rarely change). Anyway, thanks everyone for your help.

[Stu Redman]

No problem, real life should always come first. 
If you get a chance some day to check out the rc1 (or the rc2 which is also supposed to come out before release) let us know the results.
