# mytrace
|
||||
|
||||
## Prerequisites
|
||||
|
||||
1. stable rust toolchains: `rustup toolchain install stable`
|
||||
1. nightly rust toolchains: `rustup toolchain install nightly --component rust-src`
|
||||
1. (if cross-compiling) rustup target: `rustup target add ${ARCH}-unknown-linux-musl`
|
||||
1. (if cross-compiling) LLVM: (e.g.) `brew install llvm` (on macOS)
|
||||
1. (if cross-compiling) C toolchain: (e.g.) [`brew install filosottile/musl-cross/musl-cross`](https://github.com/FiloSottile/homebrew-musl-cross) (on macOS)
|
||||
1. bpf-linker: `cargo install bpf-linker` (`--no-default-features` on macOS)
|
||||
|
||||
## Build & Run
|
||||
|
||||
Use `cargo build`, `cargo check`, etc. as normal. Run your program with:
|
||||
|
||||
```shell
|
||||
cargo run --release --config 'target."cfg(all())".runner="sudo -E"'
|
||||
```
|
||||
|
||||
Cargo build scripts are used to automatically build the eBPF correctly and include it in the
|
||||
program.
|
||||
|
||||
## Cross-compiling on macOS
|
||||
|
||||
Cross compilation should work on both Intel and Apple Silicon Macs.
|
||||
|
||||
```shell
|
||||
CC=${ARCH}-linux-musl-gcc cargo build --package mytrace --release \
|
||||
--target=${ARCH}-unknown-linux-musl \
|
||||
--config=target.${ARCH}-unknown-linux-musl.linker=\"${ARCH}-linux-musl-gcc\"
|
||||
```
|
||||
The cross-compiled program `target/${ARCH}-unknown-linux-musl/release/mytrace` can be
|
||||
copied to a Linux server or VM and run there.
|
||||

||||
