this error is similar to issue addressed in https://code.forksand.com/oisf/suricata/commit/7906c521cdde5b1d0eb3ce379b8e343c3055653f
I added diff below to fix the error, maybe similar patch needed for xdp-tools ?

I was building this on Pi and ran into the same issue. Updating the lib/common.mk didn't help. Installing gcc-multilib-arm-linux-gnueabihf didn't help.

I located the file "asm/types.h". It was under /usr/include/aarch64-linux-gnu/. I added the path to C_INCLUDE_PATH
export C_INCLUDE_PATH=/usr/include/aarch64-linux-gnu/

ubuntu@ubuntu:~/dev/git/xdp-tools$ uname -a
Linux ubuntu 5.8.0-1015-raspi #18-Ubuntu SMP PREEMPT Fri Feb 5 06:09:58 UTC 2021 aarch64 aarch64 aarch64 GNU/Linux
sudo apt-get install -y gcc-multilib

On x86_64 PC, the gcc-multilib debian package makes a symbol link at "/usr/include/asm" to "/usr/include/x86_64-linux-gnu".
I guess that on the ARM32 system (Raspbian) /usr/include/asm might linked to /usr/include/aarch64-linux-gnu or arm-linux-gnueabihf

Wanted to share all dependencies I needed to get xdp-tools to build on Ubuntu 20.04

sudo apt install pkg-config
sudo apt install m4
sudo apt install libelf-dev
sudo apt install libpcap-dev
sudo apt install gcc-multilib

configure seems to cover all of these except gcc-multilib, recommend adding a check for this if its required.

Note, however, that the kernel doesn't currently support the features we
use for the XDP dispatcher on any other archs than x86_64; so you can't
actually load multiple programs on a single interface on an Arm box, and
I don't believe xdpdump will work either...

@tohojo is this still true on the latest 18.04 HWE kernel (5.4.0) for arm64?

I was able to get this to compile but as noted in two comments above, since gcc-multilib is not available on ARM64, you have to symlink /usr/include/asm to /usr/include/aarch64-linux-gnu/asm yourself and also add -I/usr/include/aarch64-linux-gnu to clang if you get the types.h as well as other subsequent errors.

Heh, yeah, 5.4 doesn't even support it on x86.

If you'd care to open a PR to fix the include issue, feel free :)

Hi, I ran into this issue where gcc-multilib can not be identified by Ubuntu 20.04. What exactly is the fix? Should I download and install the required files manually?

gcc-multilib is available in 20.04 for amd64, its not available for ARM architecture. The fix I mentioned above makes it work for ARM64. I have got XDP programs correctly compiling with normal gcc package and loading on ARM64 in AWS (though havent taken it through a full functiional test yet).

[Edit] following up on my above answer, I have tested a single XDP program and got it loading and functioning correctly on Ubuntu 18.04 with the HWE kernel on a RPi 4 and in an AWS Graviton ARM64 instance.

Example answer/notes for myself when running on Linux 5.10.103-v7l+ #1529 SMP Tue Mar 8 12:24:00 GMT 2022 armv7l.
