Hi,
It looks like it’s built with toolchain of x86 host PC. Please try the steps:

之前的错误没有,但出现了下面问题:

Hi,
So you still hit error in step 3:

Kernel Customization — NVIDIA Jetson Linux Developer Guide 1 documentation

3. Run the following commands to build the Jetson Linux kernel and its in-tree modules:

$ export CROSS_COMPILE=<toolchain-path>/bin/aarch64-buildroot-linux-gnu-
$ make -C kernel

Hello, I’m following this guide.

when I run make modules, I got same issue:

I’m compiling the kernel natively on my Jetson device.
How can I resolve this issue?

Hi,
Please have a x86 host PC. The steps are for crossing compilation on a x86 host.

10

Thank you for your reply.

Can’t I build everything natively on the Jetson without using an x86 PC?

11

NVidia dont have eloborate steps for building on native jetson I think

12

I was able to temporarily fix the error by adding KBUILD_CFLAGS_MODULE += -DMODULE at the end of the Linux_for_Tegra/source/nvidia-oot/drivers/misc/nvsciipc/Makefile.
