error: 'struct perf_buffer_opts' has no member named 'sz'

[tuxerrante]

Hi!
I'm working, as my first issue, on a Kubernetes project importing aquasecurity/libbpfgo as vendor library.
When I try to run the make deployments command to test locally my code, I get a low level error from the library (below).

VM Info:

• Ubuntu 22.04.1 LTS
• go version go1.20 linux/amd64
• Vagrant file.
• I get the same error in WSL2, reason why I switched to a virtualbox VM

SOLUTION:
As suggested by @yanivagman the problem was having the same package installed from ubuntu repo. After removing it and cleaning the cache, reinstalling the specific version from source worked:

curl -sSfL --retry 5 --retry-delay 3 \
    "https://github.com/libbpf/libbpf/archive/refs/tags/v1.0.1.tar.gz" -o- |
    tar xfz -
pushd "libbpf-$VERSION/src"
make BUILD_STATIC_ONLY=y install
popd
rm -rf "libbpf-$VERSION"

Hello,
This is Tracee repo. Libbpfgo has another repo - https://github.com/aquasecurity/libbpfgo

Anyway, it seems that the libbpf.h header you use doesn't match the libbpf version on your system.
You need to make sure that you clone the libbpf repo into your project and use both its headers and compiled binary (so) , and not any other artifacts that may already exist on the system
