I reported my finding here: https://forums.developer.nvidia.com/t/nvidia-modules-470-239-06-build-failure-with-gcc-14-due-to-conftest-sh/292645

@benjarobin: can confirm, your patches works.

I improved the second patch to properly fix warning during conftest related to EFI (instead of hiding it).

To build a package with a proper fix, do the following:

git clone https://aur.archlinux.org/nvidia-470xx-utils.git
cd nvidia-470xx-utils
curl https://0x0.st/XKB6.patch -o 0001-Fix-GCC-14-build.patch
patch -p1 -i 0001-Fix-GCC-14-build.patch
makepkg

See fixes provided by: https://0x0.st/XKB6.patch

Using -fpermissive is wrong, and introduces a major bug: The call to vmap is done with the wrong function call (missing one argument), as explained in [2].

I did create various patches in order to fix it properly, see [1] and the Nvidia fix that was back-ported [3].

To build a package with a proper fix, do the following:

git clone https://aur.archlinux.org/nvidia-470xx-utils.git
cd nvidia-470xx-utils
curl https://0x0.st/XKmG.patch -o 0001-Fix-GCC-14-build.patch
patch -p1 -i 0001-Fix-GCC-14-build.patch
makepkg

@a821, @Mechanicus: actually i tried easiest workaround which is downgrade ['gcc-libs', 'gcc'] from 14.1.1+r1+g43b730b9134-1 to 13.2.1-6 and has been compiled and worked again as previously. Thanks you folks for your efforts to find a workarounds.

@unixv: Try -fpermissive patch. Copy the context to a file, for example workaround.patch, and then apply to the repo: git apply workaround.patch

@unixv: did you read any of the latest comments / workarounds? If so, what did you try?

unixv commented on 2024-05-12 03:34 (UTC) (edited on 2024-05-12 03:36 (UTC) by unixv)

it's failed to compile and I'm no longer able to use my nvidia-470xx card .

@SoftExpert, older GCC will also work with -fpermissive flag, it is supported since GCC-4 version
