Bug ID: 47389
           Summary: Sid Meier’s Alpha Centauri Planetary Pack (GOG
                    version) ddraw crash
           Product: Wine
           Version: 4.10
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal

Terminal output of an attempt to execute Alpha Centaurl with the expansion

This is a direct continuation of my ill-fated attempt at a bug report:
https://bugs.winehq.org/show_bug.cgi?id=47388

Sid Meier’s Alpha Centauri (with Alien Crossfire expansion pack) crashes when
trying to run with Wine 4.10 on a 32-bit Debian Testing distribution. Judging
by the backtrace (see the attachment), the problem is related to the DirectDraw
implementation. If that matters, I’m using a museum exhibition grade ATI
Mobility Radeon 7000 IGP with just 16 MB of RAM (and a mostly open-source Linux
driver, with proprietary microcode; compatible with OpenGL 1.3), but I suppose
that SMAC might work even with 4 MB.

Trying to add DirectDraw=0 to Alpha Centauri.Ini didn’t fix the issue, the only
practical difference was the appearance of Firaxis Games logo followed by the
crash. Running the Alpha Centauri itself (without Alien Crossfire) didn’t work
either.

Looks like your setup or mesa problem:
---
Mesa 18.3.6 implementation error: Invalid GLSL version in
shading_language_version()
Please report at https://bugs.freedesktop.org/enter_bug.cgi?product=Mesa
---

Maybe mesa does not work very well with museum exhibition grade ATI Radeon
card...

Does 'glxgears' work for you? 'glxinfo -l' output might be interesting to see,
but overall not much chances it can be helped. You can try setting the
following values in HKCU\Software\Wine\Direct3D\ key:
MaxVersionGL 0x10000 (DWORD) value
UseGLSL disabled (string value).

See https://wiki.winehq.org/Useful_Registry_Keys.

There is a small chance that this will help.

Here’s the combined terminal output for +ddraw and +d3d. Number 4 because I’ve
saved the 2nd file for pure SMAC (without Crossfire), 3rd solely for d3d and
4th solely for ddraw.

one that isn’t about DirectX implementation.

No need to. Thanks for the additional logs & information. Your log confirms
Comment #1 with a bit of additional details. This is from your log:
---
0009:trace:d3d:wined3d_adapter_init_limits Max anisotropy: 16.
Mesa 18.3.6 implementation error: Invalid GLSL version in
shading_language_version()
Please report at https://bugs.freedesktop.org/enter_bug.cgi?product=Mesa
0009:trace:d3d:wined3d_adapter_init_gl_caps GLSL version string: (null).
---

The next line of code after printing the message with NULL GLSL version string
is:
---
TRACE("GLSL version string: %s.\n", debugstr_a(str));

/* The format of the GLSL version string is "major.minor[.release]
[vendor info]". */
        sscanf(str, "%u.%u", &major, &minor);
----

It crashes in sscanf() with NULL string received for GLSL version string.

While that's probably worth fixing in terms of returning error instead of
crashing here, unfortunately this won't let the application to run, wined3d is
unlikely willing to workaround such a problem of getting NULL GLSL version
string. Besides, the NULL string and inability to initialize shaders in GL
driver size is likely not the only problem with it on the way.

This is not a Wine bug, the only way to fix it is to fix host OpenGL driver
(maybe install some other one / version, or fix on the Mesa side). If you want
to test it further from the Wine side and is ready to build Wine from source I
can probably make a workaround patch tomorrow which will allow wined3d continue
with GLSL disabled if GLSL version string is NULL. There is a small chance that
after that you will be able to run the game with GLSL shaders disabled.

--- Comment #8 from Paul Gofman  ---
You can also try the following to workaround the problem if fixing the driver /
setup is not possible:

- Set HKCU\Software\Wine\Direct3D\MaxVersionGL to 0x10000 (DWORD hex value)
in registry;
- run with Mesa environment
MESA_EXTENSION_OVERRIDE=-GL_ARB_shading_language_100

With GL_ARB_shading_language_100 extension disabled Wine won't ask for GLSL
version string and this should allow to workaround the crash.
> From the Wine point of view, the incorrect GL driver behavior is that it

reports GL_ARB_shading_language_100 extension but then refuses to give a valid
GLSL version string. The driver itself complains in the log that things went
wrong with the string.

This is what I’ve got after setting MESA_EXTENSION_OVERRIDE. The error didn’t
trigger, but the game just showed a black screen and a few seconds later
exited. DirectDraw is not set to 0.

0009:err:winediag:wined3d_adapter_gl_init You are using the backbuffer for
offscreen rendering. This is unsupported, and will be removed in a future
version.
---

Oh... your card or driver with this card does not support framebuffer objects.
I am not sure if this is the exact reason for the black screen and exit, but
unfortunately, I am afraid this card is just generally unsupported under Wine,
at least with this OpenGL driver (I am not sure if there are other drivers
which will work with the card, but if yes, using them certainly worth trying).
Yes, I know it is DirectX 7 card which should work for DX7 on Windows, but Wine
does that through OpenGL and requires some later GL features to work.

Yet, there is a chance that some other <= DX7 games will work even under this
setup  (with MESA_EXTENSION_OVERRIDE=-GL_ARB_shading_language_100 of course).

--- Comment #11 from Paul Gofman  ---
I actually missed the point with framebuffer object, your card actually claimed
to support that initially, setting MaxVersionGL to 1.0 should have disabled it.
You can probably try running with
MESA_EXTENSION_OVERRIDE=-GL_ARB_shading_language_100 but without setting any
tweaks in registry (removing MaxVersionGL override).

It didn’t fix the issue, I’m getting the backbuffer error again.

What other OpenGL drivers can you suggest? I have xserver-xorg-video-radeon
19.0.1, latest ATI/AMD firmware, Radeon DRM 2.4.97.

That's looks strange to me. Your earlier logs from comment #3 suggest
GL_EXT_framebuffer_object support, so does your glxinfo output from Comment #4.
This extension is not there in the log from comment #9. Did anything else
besides using MESA_EXTENSION_OVERRIDE change between Comment #3 and the last
attempts? If no, can you compare the output of 'glxinfo | grep
EXT_framebuffer_object' and
'MESA_EXTENSION_OVERRIDE=-GL_ARB_shading_language_100 glxinfo | grep
EXT_framebuffer_object'? I am not sure where did this extension go.

I don't have such a card and don't have any idea which driver will work
(better) with it.

Overall, this sort of analysis looks like an offtopic here. Yet I am still a
bit curious if we can make this museum card to work with Wine ddraw. Can you
please e-mail me directly instead of writing here on these topics?

UseGLSL has been set to zero.

Running grep on glxinfo did yield GL_EXT_framebuffer_object when not setting
MESA_EXTENSION_OVERRIDE, and nothing when setting it.

My bad, I’ve meant “disabled”. And I also disabled DirectDraw in the game’s
settings.

AFAIU right now this is a driver bug. Did you report this to Mesa? If so,
please put the bugzilla link in the URL field at the top.

After the driver side is fixed it's likely that some "new" Wine bugs will
become visible. We'll probably want separate bug reports for those, but for the
time being let's resolve this bug. Please report here when / if the upstream
bug is fixed.
