How to use the binaries built, calling them by themselves, out of the context of cargo?
Closed this issue · 2 comments
By following the Hello XDP! section on the book, one ends up with 2 binaries:
- user space -> target/debug/myapp
- ebpf -> target/bpfel-unknown-none/debug/myapp
well, actually a 3rd one:
- target/debug/xtask
And one can execute the user space one through cargo xtask run
according to the documentation. Is there a way to execute the binaries out of the context of cargo? Meaning just executing the binaries... Or are the user space executables always bound to be used with cargo?
Ohh, I just missed the verbosity level when trying, but this works:
RUST_LOG=info ./target/debug/xtask run
is there a way to execute the binaries out of the context of cargo? Meaning just executing the binaries...
of course - cargo xtask run
is just a convenient, you can also run sudo ./target/debug/xdp-hello
without cargo (or copy it to other servers, and run it there, or package that binary into a docker image etc.). The "ebpf binary" target/bpfel-unknown-none/debug/myapp
is not an executable - you cannot run it by itself - it is a BPF object file that gets included into the user-space binary
