Build issue with 18.04 LTS on X86 PC

[apexintern1]

FATAL: parse error in symbol dump file
scripts/Makefile.modpost:92: recipe for target '__modpost' failed
make[2]: *** [__modpost] Error 1
Makefile:1678: recipe for target 'modules' failed
make[1]: *** [modules] Error 2
make[1]: Leaving directory '/usr/src/linux-headers-5.4.0-137-generic'
Makefile:19: recipe for target 'modules' failed
make: *** [modules] Error 2

I am getting these errors when I run the ./build-for-pc-native.sh script.

Environment is 18.04 LTS on X86 PC

Can anyone explain in detail, on how to resolve the issue?
Thank you in advance.

you need to add tab and/or -w in the grep command in the nvidia-ko-to-module-symvers in the echo command. Something like below:

May I ask what that means?

@pyt-hnu Hello, I also encountered the same problem as you on ubuntu 18.04. Is this problem solved now? I look forward to your reply.
