Recently updated the test system to Fedora 42, and everything seemed OK (including the latest VMware Workstation) – except the NVIDIA driver install..

The latest driver 570.124.04 compiles and installs OK with GCC14 and Fedora 41, on 6.13.x and also 6.14-rc kernels, but the NVIDIA source install scripts/tests etc. seem to be completely useless when compiling under GCC 15 with Fedora 42, with a compiled kernel.org kernel, but do compile/install successfully when using the Distro-supplied Fedora 42 version of the kernel (6.14.0-0.rc6.49.fc42.x86_64  rpm)….

I had thought that this might be due to an additional kernel compile selection/option being necessary, similar to the Kernel 6.12 issues, so I tried compiling the kernel using the Fedora version of the kernel config (from /usr/src/kernels/6.14.0-0.rc6.49.fc42.x86_64/config ) with ‘almost everything selected’, but the problem still occurred, so I can only assume that the Fedora-supplied kernel has some proprietary patch applied (as usual) which fixes the issue?

So, the only solutions seemed to be..  1.  Stay with Fedora 41 for the time being, or 2.  Use only the Distro-supplied kernel on Fedora 42..

Fortunately, I did find another option, which is best if you had already updated to Fedora 42…    There is a GCC 14 available for Fedora 42, at https://packages.fedoraproject.org/pkgs/gcc14/gcc14/  This results in binaries with a ‘-14’ suffix (/usr/bin/gcc-14, /usr/bin/cpp-14, etc..)

Obviously this means you would be compiling the driver with a different GCC version from the kernel, but this is possible, as follows:

in ~/NVIDIA-Linux-x86_64-570.124.04/kernel:
# export IGNORE_CC_MISMATCH=1

# CC="gcc-14" make

make[1]: Entering directory '/usr/src/linux-6.13.7'

make[2]: Entering directory '/home/rgadsdon/NVIDIA-Linux-x86_64-570.124.04/kernel'

warning: the compiler differs from the one used to build the kernel

The kernel was built by: gcc (GCC) 15.0.1 20250228 (Red Hat 15.0.1-0)

You are using: gcc-14 (GCC) 14.2.1 20250210 (Red Hat 14.2.1-8)
…………………………….
Then after compile completes successfully (but still with the usual ‘warnings’, as expected..)

I have tested this with KDE/Plasma, and VMware 17.6.3 with Win10 guest, and – so far – everything seems to be working OK…

Of course, this is not intended for a business-critical setup!
