Building with gcc-15 fails
NVIDIA Open GPU Kernel Modules Version
570.124.06
Operating System and Version
Ubuntu 24.04
Kernel Release
6.12
Please confirm you are running a stable release kernel (e.g. not a -rc). We do not accept bug reports for unreleased kernels.
- [x] I am running on a stable kernel release.
Build Command
Build using gcc-14.2 completes. Build with gcc-15.x fails with errors that were warnings in previous gcc.
Workaround is to add the following no-error statements, until the code is updated to avoid these warnings.
EXTRA_CFLAGS += -Wno-error=return-type -Wno-implicit-function-declaration -Wno-int-conversion -Wno-incompatible-pointer-types
Terminal output/Build Log
As above
Also errors
./common/inc/nv-mm.h:29:13: error: conflicting types for 'vm_fault_t'; have 'int' 29 | typedef int vm_fault_t; | ^~~~~~~~~~
./common/inc/nv-time.h:113:19: error: conflicting types for 'timespec64_to_ns'; have 's64(struct timespec64 *)' {aka 'long long int(struct timespec64 *)'} 113 | static inline s64 timespec64_to_ns(struct timespec64 *ts) | ^~~~~~~~~~~~~~~~

Builds fine with gcc-15 for me ( 570.124.04 and last update 570.133.07).

I'm using the development version of Fedora (rawhide), which started using gcc-15 in early January. I had a lot of problems at first, but Fedora has worked hard to stabilize it.
Fedora 42, not building neither 570 nor 575.
Maybe report the issue to the rpmfusion maintainers to apply the patches.

This is when trying the .run file or compiling it by hand, not using the rpmfusion packages. Switching to gcc-14 everything works as it should.
Rpmfusion added a patch (nvidia-kernel-ccflags-y.patch) for the latest 575.51.02 and fc43 rawhide ; but there is no build yet for fc42.
I can confirm that using https://github.com/negativo17/nvidia-kmod/blob/fedora-42/nvidia-kernel-ccflags-y.patch allows for compile with gcc-15 and linux-6.14.1
