How to create a static binary, or static test?

[TwoClocks]

It's very unclear to me how to create statically linked output for either binaries or tests.

There is a "linker_script" param, but I can't see any examples using it, or what the format of the param or "script" should be.

Thanks in advance.

That's controlled via the target platform. A pure Zig binary on Linux should already be statically linked. But, if it depends on a libc, then it depends on which libc you choose. The default is glibc, in which case the binary will be dynamically linked. Using musl instead will yield a static binary.

Example platform configurations can be found here.
The following should yield a statically linked binary using musl with bazel build :static:

platform(
    name = "x86_64-linux-musl",
    constraint_values = [
        "@platforms//os:linux",
        "@platforms//cpu:x86_64",
        "@rules_zig//zig/platforms/abi:musl",
    ],
)

zig_binary(
    name = "unconfigured",
    main = "main.zig",
    # ...
    tags = ["manual"],
)

zig_configure_binary(
    name = "static",
    actual = ":unconfigured",
    target = ":x86_64-linux-musl",
)

The same applies to test targets.

The linker-script attribute should not be needed here. But, an example can be found here.
