[SOLVED] Compiz Fusion + Azureus

Message

einheitlix · Post by **einheitlix** » Sat Sep 01, 2007 9:09 am

Hi,

I recently switched from Beryl to Compiz Fusion and I like it better, but I since then I couldn't get Azureus running (it worked fine before).

The problem is the following: to compile Compiz, it is required to compile libX11 with the "xcb" USE flag. Otherwise Compiz won't even start to compile, as the ebuild of Compiz from the xeffects overlay checks this.

But, as it is described in use.local.desc...

x11-libs/libX11:xcb - Support the X C-language Binding, a replacement for Xlib (can break proprietary binaries, for example Sun Java)

...now Azureus, which runs on the Sun Java VM, doesn't work anymore. It starts the GUI for a split second, then immediately crashes with the following error message:

java: xcb_xlib.c:50: xcb_xlib_unlock: Assertion `c->xlib.lock' failed.

I googled for this and it seems like compiling libX11 with xcb breaks any package using AWT/Swing with the Sun Java VM.

I thought of using the Blackdown JRE instead, but Azureus requires at least Java version 1.5.0, and Blackdown only provides Java versions up to 1.4.2.

So now I'm stuck. Any ideas on how to resolve this problem? Does anyone know if it is possible to run Azureus along with Compiz Fusion at all? Has anyone got this combination of programs working?
Any help would be greatly appreciated

have you thought about using ktorrent instead or one of the other torrent apps in Portage. The xcb use flags seems to break Java apps. There is a patch to address the issue on the xeffects forum

have a look here

I haven't tried it myself please report if it works

The following workarounds address this problem:

For sun-java5-bin:
sed -i 's/XINERAMA/FAKEEXTN/g' /opt/sun-jdk-1.5.0.12/jre/lib/amd64/xawt/libmawt.so

For sun-java6-bin:
sed -i 's/XINERAMA/FAKEEXTN/g' /opt/sun-jdk-1.6.0.02/jre/lib/amd64/xawt/libmawt.so

The same fix (applied to the appropriate file) might work for other
proprietary JDKs.

Sorry for forgot the provenance.

Thanks a lot java works with no problems. All i had to do was to substitute the amd64 for i386 in the given path.

Thanks, this solved the problem for me, too! Although this is quite a hack, it will do fine until Sun fixes its code

I didn't try the patched libX11 ebuild... for one thing, I don't really like to mess around with third-party ebuilds that don't even belong to any overlay and will certainly not be maintained, that would just be a very temporary workaround at best; plus, it seems the xeffects forums were just completely erased and the above link doesn't work anymore

Worked for me, too (dev-java/sun-jdk-1.5.0.12).

Thanks

@omidxo Thank you worked in my system too, sun-jdk-1.6 .

Didn't work for me... Although I don't have an amd64...

Athlon-xp, sun-jre-1.5.0.13

Oh well, i'm off compiling KTorrent !

just use the live-builds (9999) and disable xcb use-flag - works fine for me

both under x86 and amd64

have fun

Another thing you can try is to set 'AWT_TOOLKIT=MToolkit' as part of your environment variables. However this doesn't seem to work with Java 1.6 yet.

AFAIK compiling libxcb with -DNDEBUG flag also resolves problem with java.

good to know,

thanks

do you think it would be wise / sane to enable that flag globally ?

I read that using -DNDEBUG -DG_DISABLE_ASSERT globally might break some apps, so probably it wouldn't, although I don't know anything about -DNDEBUG itself.
