Failure in command execution from FastNetMon Advanced XDP filter Docs

[Krish Mavani]

Hi,

While setting up the XDP filter on Ubuntu 22.04 (Jammy), I followed the documentation and installed:

wget -qO- https://apt.llvm.org/llvm-snapshot.gpg.key | sudo tee /etc/apt/trusted.gpg.d/apt.llvm.org.asc

 echo -e "deb https://apt.llvm.org/jammy/ llvm-toolchain-jammy-17 main\n" | sudo tee -a /etc/apt/sources.list.d/clang.list

 sudo apt-get update

sudo apt-get install -y clang-17 libbpf-dev

However, the XDP filter build was still failing. The issue was related to missing 32-bit C development headers/libraries required during compilation.

The build completed successfully only after installing:

sudo apt-get install -y libc6-dev-i386

It may be useful to mention this package in the documentation, at least for Ubuntu 22.04 users, as others may run into the same issue during the XDP filter build process.

Has anyone else experienced this, or is there a reason why this dependency is not listed in the documentation?

Thanks.
