Did you clean your cache after upgrading?

comment:2 by GunChleoc, 17 months ago

It was a fresh checkout.

I have now gone ahead and deleted ~/cache/0ad and run make again, but it still crashes.

BTW I am getting an additional segfault when exiting from the error message window. There's the stack trace in case it is useful:

comment:3 by stanislas69, 17 months ago

Try building without the --system-nvtt flag. :)

comment:4 by GunChleoc, 17 months ago

Thanks, that fixed it :)

comment:5 by Dunedan, 17 months ago

I'm running into the same issue right now. I didn't use --system-nvtt. To be sure I also tried --without-nvtt, however this didn't help.

comment:6 by Dunedan, 17 months ago

Never mind. I skipped the step for emptying the cache. The problem is gone now, after I deleted the cache.

Resolution: invalid
Status: newclosed

Downgrading priority and I edited BuildInstructions to not suggest using the broken with-system-nvtt option. For now we will not disable it, but we might decide to do so in the future.

Priority: Should HaveMust Have
Resolution: invalid
Status: closedreopened

I think it would be best to check the version of nvtt at compile time, like we do with SM.

Stan: Would you mind if I remove your change to BuildInstructions? It is incorrect (missing cmake and libnvtt-dev is out of place), and the flag is not actually broken.

When A24 is released, I assume a number of package maintainers will update the nvtt package (especially if we put a compile-time check). So don't worry about BuildInstructions, using system-nvtt will become more commonly possible over time.

comment:9 by stanislas69, 17 months ago

Of course, you know best. I removed it because it's currently making the game not work for all the people who tried it (I actually didn't see anyone report the game worked with using --system-nvtt since your update) So I wanted to save people some time :) one of the poor fellow who tried lost a few hours because of it :/

(missing cmake and libnvtt-dev is out of place),

I didn't edit that.

When A24 is released, I assume a number of package maintainers will update the nvtt package (especially if we put a compile-time check). So don't worry about BuildInstructions, using system-nvtt will become more commonly possible over time.

None of the fixes we use are committed upstream, so I don't know if they will...

Replying to stanislas69:

So I wanted to save people some time :) one of the poor fellow who tried lost a few hours because of it :/

Yes that's why I think we should add a check, so that people don't waste their time.

I didn't edit that.

but you should have: I was just saying that your change made the instructions incorrect because your change was incomplete.

None of the fixes we use are committed upstream, so I don't know if they will...

The patches we have are completely unrelated with the pixelformat difference that causes the crash. We currently match upstream on the logic, the patches are only build fixes.

Ah I see. :)

Patch: Phab:D2765

GunChleoc, could you try applying this patch, and checking that when passing --with-system-nvtt, the game now refuses to build? Thank you!

Link to the patch so I don't have to go digging for it again:

https://code.wildfiregames.com/D2765

And the game will still build. I ran clean_workspaces.sh, then ./update-workspaces.sh --with-system-nvtt

I have version 2.0.8-1+dfsg-8.1 of libnvtt2 & libnvtt-dev listed as installed in my package manager. There is also a libnvtt-bin package available in the package manager that is not installed on my system.

Oh really sorry about that, the link I added in the Patch field will lead you directly to the patch! Writing Phab:D2765 creates short links like Phab:D2765 in Trac.

That's a bummer, thanks for testing. I will setup a Mint VM and take a look at how to detect the version.

Hello GunChleoc, I am a bit surprised, I tested the patch on Ubuntu Focal, which has the same version of libnvtt-dev (2.0.8-1+dfsg-8.1), and it works: it correctly prevents building with the system library. Mint doesn't seem to propose a package so it falls back to the Ubuntu one.

Sorry to bother you, but could you try the patch again? If it still fails, could you tell me what is the value of NVTT_VERSION which should be defined around line 50 of the system's /usr/include/nvtt/nvtt.h? And maybe run locate nvtt.h to see if you have another version of the lib laying around.

Thanks for your help!

In 23974:

Add a NVTT version check at compile-time, fixes #5757, refs #5804.

This will prevent users who have an old NVTT installed on their system from experiencing crashes. Other NVTT issues at runtime should be fixed by clearing the cache.
