Hi I write a code to print out "Hello world" in Rust and C to compare binary size. by the way, binary size compiled with rustc is too bigger than in C. I found there are many symbols in Rust binary and it looks like name mangling on C++. Can you please explain why and how to reduce binary size? B…

Have you searched? This has been posted many times before, and the answer has not changed.

Yes. First of all, you’re probably using different ways. Secondly, did you build with size optimizations? Profile: [profile.release] opt-level = 3 strip = true debug = false lto = true codegen-units = 1 C code: #include <stdio.h> main() { puts("Hello, World!"); } Rust code: #![no_main] e…

Or just the fact that Rust links statically by default for reliability, whereas most modern systems provide a dynamic C standard library and so C compilers tend to link it dynamically.
