Linking against a library in 0.11

Help
1

Hi again :slight_smile:

I need to link a program against a few libraries:

  • libc
  • X11
  • asound

With zig 0.10 I did it like this:

    const exe = b.addExecutable("xjiss", "src/main.zig");
    exe.single_threaded = true;
    exe.linkLibC();
    exe.linkSystemLibrary("X11");
    exe.linkSystemLibrary("asound");

How do I do this with zig 0.11?

ExecutableOptions structure contains boolean link_libc field, ok.
But how to link the other two, X11 and asound?
I guess one has something to do with linkage field, right?

3

Linking system libraries and libc should still work like in 0.10.
What error do you get when you try it?

Actually, I did not because I thought something has changed.
Ok, I’ll try.

if it can help you i did it like this

exe.linkLibC();
exe.addObjectFile(.{.cwd_relative = "/usr/lib/libpcre2-posix.so"});

Yes, that’s right!

const std = @import("std");

pub fn build(b: *std.build.Builder) void {

    const target = b.standardTargetOptions(.{});
    const optimize = b.standardOptimizeOption(.{});

    const exe = b.addExecutable(.{
        .name = "xjiss",
        .root_source_file = .{ .path = "src/main.zig" },
        .target = target,
        .optimize = optimize,
        .single_threaded = true,
        .link_libc = true,
    });

    exe.linkSystemLibrary("X11");
    exe.linkSystemLibrary("asound");

    b.installArtifact(exe);
}

works.
Thanks.
