How to convert addStaticLibrary() to addLibrary()?

Help
1

I’m trying to update the pulseaudio bindings for zig 0.15.1 where addStaticLibrary() no longer exists.

Does anyone have a guide on converting a build.zig from addStaticLibrary() to addLibrary()?

The options have a linkage that is set to static by default.

But a library has to have a .root_module?

uild.zig:8:31: error: missing struct field: root_module
    const lib = b.addLibrary(.{
                             ~^
/Users/edw/.zvm/0.15.1/lib/std/Build.zig:824:28: note: struct declared here
pub const LibraryOptions = struct {

I’m still a beginner to the build system.
Do I need to refactor the code to create a module, and then have addLibrary(.{root_module = mod}) as the final step?

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

const lib = b.addLibrary(.{
    .root_module = b.createModule(.{
        .root_source_file = b.path("path relative to build.zig"),
        .target = target,
        .optimize = optimize,
    }),
});

You can ofc create the module separately, especially if you want to use it for other things too.

Thanks for the help! I was able to get it working:

For future readers, you can convert like so:

// pre zig 0.14.0
const lib = b.addStaticLibrary(.{
    .name = "mylib",
    .target = target,
    .optimize = optimize,
});

becomes:

// zig 0.15.1
const lib = b.addLibrary(.{
    .linkage = .static,
    .name = "mylib",
    .root_module = b.createModule(.{
        .target = target,
        .optimize = optimize,
    }),
});

Might be worth reading this thread on the same topic as well.
