try to using go get but failed
I clone the main branch and install the libbpf of submodule.
// in libbpf/src/
make
sudo make install
Then I want to use libbpfgo in my go project by using go get command and failed.
$ go get github.com/aquasecurity/libbpfgo@main

Hi @Songrui625. I would recommend to follow the make rules from the main libbpfgo Makefile.
If you want to run go get directly you should set the CGO env vars like this: https://github.com/aquasecurity/libbpfgo/blob/245a1a13132ec0afc4a1d0f53b9317464980bcb6/Makefile#L58-L61
--- EDIT:
I think this post can be helpful: How to Build eBPF Programs with libbpfgo
Thanks @geyslan. I try to make libbpfgo as a submodule of my go project now. And seems like we must use Makefile to build my own project.
