Error when compiling Linux Kernel (BSP 6.4)

I am trying to compile the kernel for imx8x using the steps provided in:

Build Linux Kernel from Source Code | Toradex Developer Center.

When compiling I seem to be missing some dependencies but I cant figure out what I need to install :

Can you please advise as to what I need to install ?

hey @nmohan86,

In the prerequisites section for the link you gave there is a hyperlink for Install Tools and Dependence.

This should help.

I installed all the tools and dependencies:

Hey @nmohan86,

Can you verify that your host machine is setup correctly according to this.

And can you show the error logs from the command you are running to the error message.

The command I ran is:

make -j$(nproc) Image.gz 2>&1 | tee build.log

@nmohan86,

It looks like you have a mismatch somewhere between the source, the toolchain, and/or the environment.

Can you verify.

Kernel source location and toolchain installed and environment variables you are setting.

I was able to figure it out thanks! I am using the fix terminal so had to make a few modifications.
