Quoting: x_wingI ended up finishing the game (no idea about the story, I should have start by the first one :P) and didn't get any crash. I used the default Mesa packages from Ubuntu 18.04 (i.e. Mesa 19.2.8). Are you sure that the issue is related to Mesa?

All I can say is that the game crashing for me was solved when I was still able to compile Mesa as described in that forum thread, and that my experiences do match those of other players. The thread I am referencing is literally titled "Steam version of Penumbra" so I doubt it is due to my Desura copy.

Requiem's plot is always going to be out there, but yes, you would be missing out on some the character moments.

Wanted something familiar so I am doing an Ultra-Violence run of The Ultimate Doom through Crispy Doom at the moment.



It is honestly easier than these screenshots might suggest. :tongue:

Quoting: HamishFor what it is worth, I found with Requiem that the game will crash when you pick up the first audio log from Eloff Carpenter.

I've installed the game and finished the snow level (I'm now in the Alien facility... if I can call it that way XD). You get the crash when you open the log of the first level?

Yeah, it seems that what exactly triggers the game to crash is variable. I have had it crash at different points with different Mesa versions.

Yeah, same result as before sadly.

Thanks for the suggestions regardless x_wing.

That output is from my trying to use the DEBUG_CFLAGS in makepkg.conf, not from when I was exporting my own values in the PKGBUILD. Here is the relevant Meson log for that:

And Penumbra still crashes.

crossfile.ini is created from the PKGBUILD file of the lib32-mesa Arch package:
https://git.archlinux.org/svntogit/community.git/tree/trunk/PKGBUILD?h=packages/lib32-mesa [External Link]

The contents of crossfile.ini in a generated package are as follows:
[binaries]
llvm-config = '/usr/bin/llvm-config32'

As for the CFLAGS, that is being grabbed from what is defined in makepkg.conf as used by the Arch Build System. Setting the 'debug' option in the PKGBUILD makes its append DEBUG_CFLAGS which is where I was instructed to add the "-O0" flag in the linked Frictional Games forum thread:
https://www.frictionalgames.com/forum/thread-54134-post-363860.html#pid363860 [External Link]

Back in April and May adding the "-O0" flag to DEBUG_CFLAGS in makepkg.conf and toggling the 'debug' and '!strip' options in the lib32-mesa PKGBUILD did do the trick. Now doing so causes it to complain about being unable to determine the dynamic linker.

Here is the relevant parts of my makepkg.conf file:
 #-- Compiler and Linker Flags
CPPFLAGS="-D_FORTIFY_SOURCE=2"
CFLAGS="-march=x86-64 -mtune=generic -O3 -pipe -fno-plt"
CXXFLAGS="-march=x86-64 -mtune=generic -O3 -pipe -fno-plt"
LDFLAGS="-Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now"
#-- Make Flags: change this for DistCC/SMP systems
#MAKEFLAGS="-j2"
#-- Debugging flags
DEBUG_CFLAGS="-g -fvar-tracking-assignment -O0"
DEBUG_CXXFLAGS="-g -fvar-tracking-assignments -O0"

I have tried exporting my own CFLAGS in the PKGBUILD containing just the "-O0" flag and with that I can get the lib32-mesa package to build, but Penumbra will still crash when using these builds. I have also tried using the Meson c_args option to set the "-O0" flag to no good effect. I have also tried setting the various "-mno-sse" flags which again do nothing.

Attempting to build the lib32-mesa package as described before now just results in this error:

Which is kind of annoying as I never got around to completing Requiem yet.

So my lovely little Gigabyte Radeon RX 460 arrived last night. I can now confirm that on this card using AMDGPU I am getting crashes not only when I flatten the coin in the vice at the start of Black Plague but also when I leave the fishing boat at the start of Overture once again.

Turns out I still have my old Desura receipt:


I have got my ten dollars worth I have to say.
