Fortunately, there is already a fix\/workaround for this, and details can be found on the NVIDIA Forum, at https:\/\/forums.developer.nvidia.com\/t\/nvidia-modules-build-failure-with-upcoming-gcc-14-and-recent-kernels-due-to-misfiring-conftest-sh-test-heads-up\/279072<\/a><\/p>\n

I have successfully applied this to 550.54.14 (with some fuzz..), and it now compiles and runs OK..\u00a0\u00a0\u00a0\u00a0\u00a0 Thanks to ionen<\/em><\/strong> on the forum for providing this….\u00a0\u00a0 Hopefully, NVIDIA will release a driver version that addresses this..<\/p>\n

It is worth mentioning that the latest VMware 17.5.1<\/strong> patchset is OK with GCC 14… at https:\/\/github.com\/mkubecek\/vmware-host-modules\/tree\/workstation-17.5.1<\/a><\/p>\n
