Ubuntu Oneiric 64-bit Bumblebee should recommend virtualgl-libs:i386 about bumblebee

[Lekensteyn]

I don't know how to depend on a different arch, when I set virtualgl-libs:i386 [amd64], I get a build error. Do you have a clue?

[jethrogb]

No idea. I have found these two pages: http://wiki.debian.org/Multiarch https://wiki.ubuntu.com/MultiarchSpec

@jeihrogb: Thanks for mentioning. I installed lib32-virtualgl in ArchLinux and it seems that OpenGL games in Wine have a better result now but for example Warcraft 3 still crashes which seems to be a VirtualGL related issue (how can i create a logfile for VirtualGL?):

onny: For Warcraft III, it is better to run war3.exe directly instead of using the wrapper executables provided by Blizzard. I'm using these command lines to start the game:

TFT: optirun wine "/media/data/Games/Warcraft III/war3.exe" -opengl
ROC: optirun wine "/media/data/Games/Warcraft III/war3.exe" -opengl -classic

For best results (in-game videos, alt-tabbing, etc.) you might also want to play around with the settings in the 'Graphics' tab of the wine configuration.

Well, somehow VirtualGL has some issues on X64-Systems when running a 32bit application: http://osdir.com/ml/hybrid-graphics-linux/2011-06/msg00023.html (nearly same error)

[Lekensteyn]

@onny Please create a new issue for your WoW issue. This does not seem to be a 32-bit vs 64-bit issue.

[onny]

thanks for your support Lekensieyn. Well, it got a bit wired, running: sudo optirun Frozen\ Throne.exe -opengl launched the game without any problems (after a .wine-directory was created for root). I tried it a second time but then it failed, even after removing /root/.wine again. Are there any more temporary or cache folders which I can remove to reproduce this situation? I guess on a 32bit system it wouldn't be so complicated.

[Lekensteyn]

Are you crazy? Running wine as root is a BAD idea. Use the command find ~ -user "$USER" -ls to find out what folders in your home directory have the wrong permissions.

[Lekensteyn]

Ok, I found out how to make this dependency:

• bumblebee:amd64 recommends on virtualgl-libs-ia32
• virtualgl-libs-ia32:i386 is a dummy packages declared Multi-Arch: foreign and depends on virtualgl-libs

What about an alternative that does not involve rebuilding virtualgl:

• bumblebee:amd64 recommends bumblebee-ia32
• bumblebee-ia32:i386 is a dummy packages declared Multi-Arch: foreign and depends on virtualgl-libs

Thoughts on the second idea?

[ArchangeGabriel]

Looks fine.

[jethrogb]

It depends on who's packaging virtualgl. If you go with the first approach, other software could also make use of this package.

[Lekensteyn]

I am the VGL packager for the Ubuntu PPA. The point is, virtualgl-libs or virtualgl does not depend on the 32-bit libs itself. Bumblebee on the other hand can profit from the 32-bit virtualgl-libs package.

[Lekensteyn]

Fixed in bumblebee/testing on Precise. It'll be copied to stable soon.

[ArchangeGabriel]

Currently being fixed by Lekensteyn for Oneiric and Precise, will probably be pushed today.

[ArchangeGabriel]

Fixed, published on testing, will arrive on stable soon. Closing.
