Conftest failed error while trying to install nvidia-455 / 450 driver in debian

Hi

I am having trouble installing the LINUX X64 (AMD64/EM64T) DISPLAY DRIVER v455.45.01

I am attaching the make.log generated during the process. Its related to conftest failed problem reported by several users previously for different versions. This I observed even while trying to install the nvidia-current-450.80.02.

Kindly help.

I have GTX 1650 Nvidia card
debian 4.19.0-13-amd64 x86_64

make.log (79.1 KB)

I also tried using NVIDIA-Linux-x86_64-435.21
Here is the failed log.

Looks like a version mismatch between your current system compiler (gcc) and the gcc the kernel was compiled with.

my gcc version is 8.3.0
I also have gcc 7.4.0-6

can I know which one I need ?

Also, how can I make out from the log for this mismatch ?

Boot the kernel you’re building for (4.19.0.13)
then run
dmesg |head -n5
the topmost line should display the kernel version and the gcc version used.
The explicit version check was removed from the driver installer a while ago so it unfortunately needs a little experience to notice it. Odd conftest failure point to this.
Furthermore, you’re using the .run installer, which is not advisable. Rather use a packaged driver from repo.
At least you should also use the --dkms option when using the .run installer.

Hi

When I used the command and
CC=gcc-7 ./NVIDIA-Linux-x86_64-435.21.run --kernel-source-path=[path]

It displays that the kernel was built with gcc 8.3.0 which is the default gcc and it aborts.

I reran with
./NVIDIA-Linux-x86_64-435.21.run --kernel-source-path=[path]

this uses gcc 8.3.0 but generates the error log.

This does not look like gcc version problem.

please post the output of
cc -v
and
gcc -v

Looks fine. The conftest failures nevertheless point to something wrong with your build system. Please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post.

Looks normal.
Which version of binutils do you have installed?
dpkg -l |grep binutils

Hi. Thanks for the help.
I think, you are right about some config problem.
I reinstalled, as the broken dependencies were not easy to fix, and upgraded to sid, and got the drivers installed now.
