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: --- a/kernel-module/nvidia-ko-to-module-symvers +++ b/kernel-module/nvidia-ko-to-module-symvers @@ -11,14 +11,14 @@ syms+=(nvidia_p2p_dma_unmap_pages)

• crc="$(objdump -t "${nvidia_ko_fn}" | grep "_crc${sym}" | awk '{print $1}')"
• crc="$(objdump -t "${nvidia_ko_fn}" | grep -w "_crc${sym}" | awk '{print $1}')" if [ -z "${crc}" ]; then echo "Warning: Can't find symbol ${sym} in ${nvidia_ko_fn}; assuming CONFIG_MODVERSIONS=n so setting CRC=0" crc=00000000 fi sed -i '/${sym}/d' "${symvers_fn}"

May I ask what that means? --- a/kernel-module/nvidia-ko-to-module-symvers +++ b/kernel-module/nvidia-ko-to-module-symvers @@ -11,14 +11,14 @@ syms+=(nvidia_p2p_dma_unmap_pages)

And I didn't solve the problem by following this method. [#!/bin/bash

@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.
