I wrote a little game using Rust, and I used cargo build --release to compile a release version on Mac.
I tried to share this with my friend who is using Ubuntu, but when he tried to run the binary, he got the following error:
cannot execute binary file: Exec format error
I searched for this but found no answers. Doesn't Rust claim to have "no runtime"? Shouldn't it be able to run anywhere in binary form?
Rust not having a runtime means that it doesn't have a lot of code running as part of the language (for example a garbage collector or bytecode interpreter). It does still need to use operating system primitives (i.e. syscalls), and these are different on MacOS and Linux.
What you want is a cross compiler. If you're using rustup, then installing a cross compiler should be simple:
# Install the toolchain to build Linux x86_64 binaries
rustup target add x86_64-unknown-linux-gnu
Then building is:
cargo build --release --target=x86_64-unknown-linux-gnu
Caveat: I don't have an OS X machine to test this on; please comment or edit to fix this if it works!
Well, it is because Rust has no runtime (unlike e.g. Java's JVM) that you can't just compile code on one OS and expect it to run on a different one; what you are looking for is cross-compilation. I haven't done it in Rust, but from what I can gather you can find relevant information on different cross-compilation Rust strategies on this GitHub repo.
