Decided to try and compare the general base program size of several languages. I wrote a handful of Hello World programs, and stripped them of everything. Here's the final results in KiB:
strip -s -o ${lang}_strip
du *_strip
C: 16
C++: 16
Go: 1204
Hare: 220
Rust: 352
#programming #compile #c #cpp #go #golang #hare #harelang #rust #rustlang

@synlogic @drewdevault You both replied while I was in the middle of writing the followup 😅
I wanted to test default compiling behavior, which means for at least C and C++ results in dynamically linked binaries.

@omenos @synlogic gotcha. fwiw I can get down to 14K with a statically linked Hare binary which is a bit contrived:
use rt;
export fn main() void = {
const msg = "Hello world!\n";
rt::write(1, &(&msg: *[]u8)[0], len(msg))!;
};
hare build -Ro main main.ha
strip main

Something to note is that Golang and Hare are the only two actually static binaries of the bunch. C, C++, and Rust are all dynamically linked to some degree (libc, libstdc++, libgcc_s, libm).

@drewdevault @synlogic Haha, yeah. I figured there are clever ways of getting "as close to the metal" as possible, I was only looking at general usage.
C: printf("Hello, World!\n")
C++: std::cout << "Hello, World!" << std::endl
Go: fmt.Println("Hello, World!")
Hare: fmt::println("Hello, World!")
Rust: println!("Hello, World!")

@omenos @synlogic makes sense. I got 117 KiB for that program, but it's probably just a difference in Hare versions. I wouldn't nitpick except that this puts us at under half of the size of Rust and I'll take that W :)

@drewdevault @omenos @synlogic btw about the clang vs. gcc thing on musl, it seems like it's about packing code efficiently as size(1) reports very similar numbers for both while the binary generated by gcc has three large chunks of zeroes which the clang one doesn't have.

@lanodan @drewdevault @synlogic glibc does tend to provide... larger binaries considering how much is going on in the libraries. I'm going to run a quick test comparing GNU libstdc++ to LLVM libc++.
