nvidia340-dkms fails to build

[bsduck]

System

• xuname:
  Void 4.19.69_1 x86_64 GenuineIntel uptodate rF
• package:
  nvidia340-dkms-340.107_3

Expected behavior

The kernel module should be built and installed

Actual behavior

The build fails with following error message:
ERROR: Kernel configuration is invalid include/generated/autoconf.h or include/config/auto.conf are missing. Run 'make oldconfig && make prepare' on kernel src to fix it.

Running make oldconfig && make prepare gives an error as well:
scripts/kconfig/conf --syncconfig Kconfig scripts/Makefile.build:45: arch/x86/entry/syscalls/Makefile: No such file or directory make[1]: *** No rule to make target 'arch/x86/entry/syscalls/Makefile'. Stop. make: *** [arch/x86/Makefile:245: archheaders] Error 2

Steps to reproduce the behavior

Install nvidia340

It works fine here. Are you sure the kernel headers are installed properly?

[bsduck]

linux4.19-headers package is installed. May there be some manual task needed for the headers to be installed properly?

You can see my complete log if it cans help you.
make.log

Please check your /usr/bin/cc symlink. If it points to clang or any other compiler that is not gcc, use xbps-alternatives to set it back to gcc. The errors look like the wrong compiler is used to build the kernel module.

You're right! It works fine now. Thank you.

Seems not to work with linux5.2 (which just became default). Here is my log again.
make.log

That is indeed an issue with the package. nvidia340 was only tested on i686 up to now and this architecture doesn't have the uvm module. I will see if I can find a way to patch this once I have time to test myself.
