On my Ubuntu 24.04 LTS and Pktgen I do not see this error. I am compiling for x86_64 machine what is the OS used and the type of machine building pktgen?

This error is present in Ubuntu 22.04 LTS. I made it work by modifying the formatting, exactly according to the error.

On my Ubuntu 24.04 LTS and Pktgen I do not see this error. I am compiling for x86_64 machine what is the OS used and the type of machine building pktgen?

My OS is: Ubuntu 22.04.3 LTS and the machine type is x86_64

Now,I have another question,I need to cross-compile for aarch64 machine ,How can I do it?
I tried to use meson to specify the configuration file, but encountered an issue that caused an error when using ninja.

The following are the operation steps:

Not going to be much help here as I only compile for x86_64.

It appears strlcpy does not exist in the build.
