Zig with C

This is a very simple example to demonstrate how Zig works with C.

Run

Use below script to run.

zig build run

Test

Use below script to test.

zig build test

The magic

It's in build.zig, the magic code is here. (You may change or add more flags in c_args.)

fn withC(exe: *std.build.LibExeObjStep) void {
    const c_args = [_][]const u8{
        "-std=c99",
    };

    exe.linkLibC();
    exe.addIncludePath("src/vendor/include");
    exe.addCSourceFile("src/vendor/myadd.c", &c_args);
    exe.addCSourceFile("src/vendor/mytime.c", &c_args);
}

Invoking the function withC for zig build run,

    ...
    const exe = b.addExecutable("zigwithc", "src/main.zig");
    exe.setTarget(target);
    exe.setBuildMode(mode);
    withC(exe);
    ...

and zig build test.

    ...
    const exe_tests = b.addTest("src/main.zig");
    exe_tests.setTarget(target);
    exe_tests.setBuildMode(mode);
    withC(exe_tests);
    ...

That's it.
