Just creating a ticket with a reference for easy access:

[Douglas R. Reno]

Mesa has a crash at runtime when compiled with GCC 14. It happens on AMDGPU cards in the si_llvm_optimize_module function.

[Xi Ruoyao]

Replying to Douglas R. Reno:

Mesa has a crash at runtime when compiled with GCC 14. It happens on AMDGPU cards in the si_llvm_optimize_module function.

It's triggered by LTO: ​https://gitlab.archlinux.org/archlinux/packaging/packages/mesa/-/commit/c3e9f807291589f75da76aa9ecabe59818139f95

and we don't enable LTO for BLFS Mesa.

P.S. Anyway they should report it to the upstream instead of just hacking it around in the distro.

QCA and evolution-data-server FTBFS with GCC 14+

[Rahul Chandra]

webkitgtk also FTBFS, but clang seems to fix it

Replying to Rahul Chandra:

Evolution-data-server builds fine for me.

[Xi Ruoyao]

Replying to Rahul Chandra:

webkitgtk also builds fine for me. Can you post how it FTBFS?

[Xi Ruoyao]

PLEASE paste the error message for a FTBFS and try to search in the upstream bug tracker if you hit it. And PLEASE do not duplicate a report from another distro w/o investigation.

[Rahul Chandra]

Sorry, it was really late last night so I didn't want to report the errors upstream without further investigation, here are the errors,

evolution-data-server (doesn't build with clang either with the same error might be something else): 
Camel-1.2.gir:42980.7-42982.16: warning: Field `Camel.Provider.auto_detect' conflicts with method of the same name

Give me a second to get the rest

QCA (Doesn't build with clang, might be a chroot issue):

<command-line>: error: unable to find string literal operator 'operator""C' with 'const char16_t [65]', 'long unsigned int' arguments

Replying to Rahul Chandra:

QCA (Doesn't build with clang, might be a chroot issue):

Isn't this a gcc ticket?

[Rahul Chandra]

yes, because it doesn't build with gcc or clang, I have confirmed it's not a chroot issue.

[Rahul Chandra]

I need to investigate more if it's working for Xi.

[Bruce Dubbs]

qca build for me with gcc-14, but I had about 150 warnings, most for deprecated usage.

[Rahul Chandra]

Interesting I somehow got QCA and Webkitgtk working?? The only thing I can think of is that I gave my system a reboot but I don't see how that would affect anything. evolution-data-server is still broken for me though.

[Rahul Chandra]

Sorry for the noise, seems like my vala build was corrupted, rebuilding vala fixed the issue.

[Xi Ruoyao]

Use the same Vala version as the book says. Old Vala may build fine but then produce some C code rejected by GCC 14.

[Bruce Dubbs]

I'm going to close this ticket. If there are new gcc14 issues that pop up, lets make individual tickets for the affected package.
