Can't build nvidia driver on Linux 4.19 (Ubuntu 20.04)

NVIDIA Open GPU Kernel Modules Version

545.29.06

Operating System and Version

Ubuntu 20.04.4 LTS

Kernel Release

4.19.112-0062 (Custom)

Build Command

When building the NVIDIA driver, I encountered an error where ld couldn't find a series of .o files. I am using a custom kernel, and the project can be found at https://github.com/Soheil-ab/sage/. I want to install the NVIDIA driver for this kernel. I tried compiling from source code and also attempted to install using NVIDIA-Linux-x86_64-535.146.02.run, but both failed. However, when I switched to the default 5.4.0-169-generic kernel in Ubuntu, I was able to compile the driver successfully. I suspect that there may be an issue with the custom kernel, and I'm wondering if there are any specific kernel requirements for compiling the driver. How can I resolve the aforementioned problem?

The report names kernel-open/nvidia and the custom kernel release 4.19.112-0062; begin by reproducing the module build with that kernel and compare it with Ubuntu's 5.4.0-169-generic build. Inspect the reported missing .o paths and build log; done means establishing whether the failure is in this repository or the custom kernel and documenting actionable kernel requirements.
