Emitting an Executable
The commands zig build-exe
, zig build-lib
, and zig build-obj
can be used
to output executables, libraries, and objects, respectively. These commands take
in a source file and arguments.
Some common arguments:
-fsingle-threaded
, which asserts the binary is single-threaded. This will turn thread-safety measures such as mutexes into no-ops.-fstrip
, which removes debug info from the binary.--dynamic
, which is used in conjunction withzig build-lib
to output a dynamic/shared library.
Let's create a tiny hello world. Save this as tiny-hello.zig
, and run
zig build-exe tiny-hello.zig -O ReleaseSmall -fstrip -fsingle-threaded
.
const std = @import("std");
pub fn main() void {
std.io.getStdOut().writeAll(
"Hello World!",
) catch unreachable;
}
