Add compile instruction to compile profile-bee?

[vincentmli]

Hi,

Could you add instruction to compile profile-bee, sorry totally newbie to rust here :)

Hi @vincentmli all you need to do is mentioned here. https://github.com/zz85/profile-bee#development

In case you are not familiar with cargo and friends you should read something about in the rust book. Let me drop a link. https://doc.rust-lang.org/cargo/

@tippexs thanks for the reply, I had this error

Hi all, the repository have been updated to work with the latest rust and crates version.

as from the README, try running

cargo xtask build-ebpf
cargo xtask run

and let me know if you still encounter errors.
