Inspecting ELF files from Cargo builds.
On MacOS, Cargo won't build ELF files by default when running cargo build.
Instead, the file will be of type Mach-O, which is an arm64 Mac-specific
executable.
ELF files are produced by cargo build by default on Linux operating systems,
so I've opted to use Docker for now.
I will record the steps to link MacOS architecture with a target Linux architecture for Cargo builds and ELF file inspections, just not now.
Use Docker to spin up a Linux Rust container.
docker run -it -v $(pwd)/elf-project:/elf-project rust
cd elf-project
cargo build --release
The ELF file will be located at target/release/elf_project.
