I solved this problem by install bpftool manually.

git clone --recurse-submodules https://github.com/libbpf/bpftool.git
cd bpftool/src
sudo make install

I solved by adding a symlink with uname -r name in: /usr/lib/linux-tools:

There also has to be appropriate linux-tools-* package present.

you need to be more careful, because wsl has modify kernel to nat between windows localhost and linux localhost, struct ipdhr is different from the original one.

@zaoying yes, I'm aware. It works as I see, no issues so far in my scenarios. However, I did compile bpftrace from sources with WSL2 kernel headers, for the reason you highlighted.

Anyways, it's just a workaround.

Hi everyone, I'm trying to use your suggestions to get use of BPF, EBPF, or LinuxTC with WSL, but I'm still unable to use them. Can you help me to solve this? i will be very grateful if you can share the script to follow in a way to have your same scenario, and work also for me

[zaoying]

Would you like to share some logs?

yes, i obtain the same result of the starting of this issue report (even after trying different potential solutions):

bpftool -V

so, basically, I m trying to use LinuxTC, BPF e EPBF (and tools implementing them) on WSL2 on Windows. I m trying different code, different repositories, but they never work
