Can anyone get the SL viewer to run under Wine on Linux any more? Crashes with uncaught C++ exception during login.

[animats]

Until recently, it was possible to run the Second Life viewer under Wine on Linux. That's no longer working. I hardly ever bother to run the SL viewer, but I'm working with someone who is trying to set up pathfinding with the SL viewer. They can't find the right menus. and the LL documentation has screenshots of totally different menus from the distant past.

Fortunately, I can still run the Puppetry project viewer! So I don't have to fix LL's code.

What seems to be broken is the "SL Version checker". That hasn't worked under Wine for years. Crashes because it wants some DLL Wine doesn't have. But until recently, that didn't matter. Now, for some reason, when it aborts, LLLogin::loginCoro fails with an unhandled C++ exception during login. Look at the code around line 232 of lllogin.cpp. It looks like if the login response has "wait_for_updater" set, it's forced down a path that requires updater success. I think.

Also,

• media_plugin_cef.dll now fails. This is new. 2023-12-29T22:36:15Z WARNING #Plugin# llplugin/llplugininstance.cpp(106) LLPluginInstance::load : apr_dso_load of C:\Pro

No, I'm not going to file a JIRA. I'll get the same "Linux is not supported" response as last time.

I can't say I've ran it recently, but I was using the SL Viewer via Wine during PBR testing and didn't have issues beyond the python issue.

This two-facedness needs to be brought up at a TPV meeting - I believe DaveP has stated recently that LL is "definitely open for Linux PRs", so if they aren't, then complaining about it and pointing to the PR might get some traction behind it.

Which version? I was using 7.1.1. A few versions back, it worked. Released 6.6.10 works on the same machine. So, somewhere between 6.6.10 and 7.1.1, something was broken.

I can live with LL not supporting a full Linux version, but it ought to as least work under Wine, like most other games.

I warned @Vir Linden about this crash fest under Wine, at the last Open Source development meeting.

I suggested him to check what MSVC version was in use to build the viewer on github: MSVC1937 is the culprit for systematic crashes I myself saw happening with my own viewer (and I had to do an emergency update with a build done after I reverted my build system to MSVC1936, which Micro$oft exceptionally allowed in the VS installer, demonstrating they knew their 1937 version was bogus). MSVC1938 has since been released and does not cause crashes any more...

This is not to say that the crashes you are seeing are indeed due to this (potential) issue, since this could just as well be some code in LL's viewer triggering a Wine bug (it won't be the first time), but I now can run the latest official viewer I downloaded (v7.1.2.7215179142) without seeing it crashing every few seconds under Wine, so either LL updated from MSVC1937 to MSVC1938 on github, or the new viewer version is not triggering any more a Wine bug...

Checking now, Second Life Release 7.0.0.580782 (64bit) seems to work under Wine on my system.

IIRC, the systematic crashes were seen with v7.1.1.something...

[animats]

Hm. I just downloaded 7.1.2.71xxx, the PBR maint viewer, and it crashed. I have the debug info.

First, the updater crashes with a subscript out of range in Python code. (Where's the source code for the updater, anyway.)

Subscript out of range in Python. Should be easy to fix.

Then the CEF plugin fails:

This doesn't happen with viewer 6.6.10.

The viewer offers the login screen, and I log in.

Then, the full crash:

wine: Unhandled page fault on write access to 0000000000000000 at address 00000001411C4612 (thread 0288), starting debugger...

This is what happens in C++ when you de-reference a null pointer.

Trouble is in Login::Impl::login_, which is where the results from the updater are received and dealt with.

Looks like this build doesn't have debug symbols, so the backtrace is just numbers. I have the full log, of course; ask if you want a copy.

Now, in 6.6.10, the updater still crashes, but it doesn't take down the whole viewer. Nor is the CEF plugin crashing.

 

[animats]

Where is SLVersionChecker.py source, anyway? I can't find it on Github. Whatever is causing a subscript out of range over there can't be too hard to fix.

[Henri Beauchamp]

Oh, you mean that crash with the version checker ?

Yes, it always crashed for me under Wine... But, you can simply delete SLVersionChecker.exe (or whatever they call it exactly), and the viewer will then start just fine: it will complain that it can't start the version checker, but will keep running nonetheless.

As for the CEF plugin, it should work... It does for me.

Works for me, as long as I have a pure install of wine in my /home directory.  No winetricks, dxvk or MS DLLs added. I use the development branch. Still crashes occasionally, but it works better overall.

It's the same for the other Windows viewer I use most with Wine, Black Dragon. For me, that one is more stable in Wine vs the LL viewer, I can run an hour or so with that before it crashes (if it does at all, it runs with fewer errors shown in the terminal).

Of the LL viewer, or of Wine? Please give versions of everything. Thanks.

Right now, Wine 9.0-rc3.

Ah, I'm at Wine 8.1, the default shipped with Ubuntu 22.04 LTS. Time to try newer Wine versions. Thanks.
