Can't build NVIDIA akmod, GCC "unable to produce objects" error

Hi folks,

I just updated my system a few hours ago and rebooted as normal. Since then, I have been trying to get it to boot up normally, but it won’t work. I’ve gotten into a TTY, and have discovered that the NVIDIA akmod isn’t loaded and fails to build manually (module not in any modprobe results). Below is the log of the akmod build. As you can see, it thinks GCC is broken, so I’ve tried everything I can think of to reinstall/repair GCC, and none of it works. Not sure what to do. Please help!

The C compiler 'gcc' does not appear to be able to
create object files.  Please make sure you have
your Linux distribution's libc development package
installed and that 'gcc' is a valid C compiler
name.

Disk full?
Selinux permission issue maybe?

3

There’s about 300GB of free space and nothing on the SELinux tab in Cockpit, so not those

4

BUILDROOT is

/tmp/akmodsbuild.PWV9w10A/BUILD/
5

That’s on my root partition, so same amount available

Hi Micha,

Do you have mixed up RPMFusion NVIDIA packages perhaps? I noticed this, but I don’t know if it matters per se, because I use nvidia-open myself.

So my take on the info you’ve provided is that akmods thinks it’s the regular “nvidia” proprietary kmod but some reason it siwtched to nvidia-open. They are two different directories/paths.

I am not an RPMFusion expert, but check your nvidia packages. I’d advise to only have the type you’d want to use, e.g. I don’t install both when I do my NVIDIA upgrades. I only build nvidia-open (for my computers).

I would “guess” that both types can coexist, but I don’t know that for certain. Here’s what my setups look like (I only keep two kernels because of /boot space):

$ rpm -qa | grep nvidia | grep -E 'akmod|kmod' | sort -ud
akmod-nvidia-open-580.126.18-1.fc42.x86_64
kmod-nvidia-open-580.126.18-1.fc42.x86_64
kmod-nvidia-open-6.18.12-100.fc42.x86_64-580.126.18-1.fc42.x86_64
kmod-nvidia-open-6.18.13-100.fc42.x86_64-580.126.18-1.fc42.x86_64
xorg-x11-drv-nvidia-kmodsrc-580.126.18-1.fc42.x86_64

You also may want to $ rpm -V <all your NVIDIA packages and kernel packages> to verify that they are sane/complete.

Actually /tmp is by default kept in RAM as can be seen with the mount command.

$ mount | grep /tmp
tmpfs on /tmp type tmpfs (rw,nosuid,nodev,seclabel,size=16386700k,nr_inodes=1048576,inode64,usrquota)

Please show us the output of lsblk -f so we can see the capacity and usage of drive space.

Also the output of inxi -Fzxx and dnf list --installed \*nvidia\* as well as free

That message in your post (the last line) tells you exactly where to find out the cause.

Please run tail -100 /var/cache/akmods/nvidia/580.126.18-1-for-6.18.13-200.fc43.x86_64.failed.log and post the output here so we can see what the log tells you about the cause. It should assist us to assist you in solving the problem.

The “shotgun” approach to solving an issue often wastes time and effort, and does not necessarily fix the problem since it does not directly address the actual cause.

No, this is not the reason: akmod-nvidia includes nvidia-open and auto
detect to use it or not since Apr 29 2025.

nvidia-kmod.spec excerpt:

    * Tue Apr 29 2025 Nicolas Chauvet <kwizart@gmail.com> - 3:575.51.02-4
    - Add nvidia-open auto-detection script

The akmod log posted initially by the OP is exactly this entire failed.log file.
This file cites itself as its last line. This is misleading :frowning:

10

That said, it would be nice, as suggested by Rallen, to list and verify all the nvidia
packages you have.

Using dnf for listing will show from what repo. Post thus the output of:

  • dnf --color=no list --installed \*nvidia\*

Verify with:

  • rpm -V $(rpm -qa \*nvidia\*)
11

Post the output for this command

echo 'int main(){return 0;}' > sanity_test.c && gcc -c sanity_test.c -o sanity_test.o && echo "SUCCESS: GCC created an object file." || echo "FAILED: GCC still cannot create object files." ; rm -f sanity_test.c sanity_test.o
