Hi

Amule used from svn problems occoure since 9732 and not changing go forward to 9755 or use the before running 9721
after typing amule in command prompt get (Speicherzugriffsfehler) memory segmentation fault
Created a backtrace (rebuilded crypto++ not help)

Can some help?

Hi MasterKGB!

[MasterKGB]

Tjo ich geh nicht verloren

[Stu Redman]

As you can see, crash occurs deeply inside cryptopp and is probably not related to aMule.
What version of cryptopp are you using? If it's 5.6.0 try using 5.5.2 instead.

Amule used from svn problems occoure since 9732 and not changing go forward to 9755 or use the before running 9721

Huh ? Is the problem now related to a certain SVN version or not ? (If you have problems with English you can also post in German, but please do it in the German board.)

And please don't post in German here, both of you. The others don't like it. I don't like it either if people post in, say, Finnish.
For the others: It was just a little greeting, nothing of interest.

[MasterKGB]

OK, THX changing to crypto++-5.5.2-r1 resolve the problem.

Sorry haven't read that there are problems using the 5.6.0

Amule used from svn problems occur since 9732 and not changing go forward to 9755 or use the before running 9721

Sorry forgot to type ", and ." it Only mean:
I use the SVN version. My Problem occur since I tried to compile the SVN 9732. Then I tried compiling the 9755 with the same Problem.
Now I tried go back to the SVN 9721 and receive the same message.
After trying to create a Backtrace i saw the problem with crypto++. I recompiled it with no result. Is it written somewhere? The Problem using 5.6?

Sorry for the german greating above, can be deleted!

[Stu Redman]

Is it written somewhere? The Problem using 5.6?

Just personal experience. I think they are overdoing the optimizations and it's getting out of hand on certain platforms.
Problem is, all those bugs with it are hard to grasp and thus hard to report.

There was a discussion about this issue on the CryptoPP users group, but nothing came from it.

[MasterKGB]

Maybe create for amule a bad list of packages

Only a joke, cause much time needed for that.

[GonoszTopi]

(rebuilded crypto++ not help)

I hope you know (and did) that after rebuilding Crypto++ you must also rebuild aMule.

nothing of interest.

Move on, nothing to see here!

[MasterKGB]

Yes of course I know and done
And tried 5.6.0 an 5.6.0-r1

Both not working

[Stu Redman]

Please try the following patch with 5.6.0 (or 5.6.0-r1) and tell me if it fixes the problem.

[MasterKGB]

have I done something wrong?
tried to emerge crypto-5.6.0-r1 with that patch and got that output:

If done it in the section src_prepare (fyi)

[GonoszTopi]

This patch is for aMule, not for Crypto++.

[DarkNRG]

I had a similar problem with aMule and crypto++ and could solve it by enabling SSE3 support in crypto++ despite my cpu doesn't support sse3 according to /proc/cpuinfo.

PS: I'm using gentoo so maybe it was some gentoo-specific patch of crypto++ which didn't like aMule.

[Stu Redman]

Please try the following patch with 5.6.0 (or 5.6.0-r1) and tell me if it fixes the problem.

Now what? Still around?
I hate it when people come and ask for help and then drop away again. 

[wires]

I'm not suffering this issue but patch applied to SVN 9803 and amule is still working. At least you have a regression test on AMD64 arch (Fedora 11)

Edit: cryptopp-5.6.0-1.fc11.x86_64

Cheers
