Cannot build a target for linux arm64

[seungduk-yanolja]

Hello there,

First of all, thanks for the great work.
Using the following rule, I am trying to integrate a CPP library into a Go package.

# This rule is defined for each architecture in each directory.
cc_import(
    name = "banana_lib",
    static_library = "libbanana_static.a",
)

go_library(
    name = "banana",
    srcs = glob(["include/**/*.h"]) + [
        "cfunc.go",
        "banana.go",
    ],  # keep
    cdeps = select({
        "@io_bazel_rules_go//go/platform:linux_arm64": [
            "//test/banana/linux_arm64:banana_lib",
        ],
        "@io_bazel_rules_go//go/platform:linux_amd64": [
            "//test/banana/linux_amd64:banana_lib",
        ],
        "@io_bazel_rules_go//go/platform:darwin_amd64": [
            "//test/banana/darwin_x86_64:banana_lib",
        ],
        "@io_bazel_rules_go//go/platform:darwin_arm64": [
            "//test/banana/darwin_arm64:banana_lib",
        ],
        "//conditions:default": [],
    }),
    cgo = True,
    clinkopts = ["-lpthread -lstdc++"],
    data = [":banana_dict"],
    importpath = "seungduk.kim/test/banana",
)

It requires a toolchain, so I imported bazel-zig-cc in WORKSPACE.

BAZEL_ZIG_CC_VERSION = "v1.0.1"

http_archive(
    name = "bazel-zig-cc",
    sha256 = "e9f82bfb74b3df5ca0e67f4d4989e7f1f7ce3386c295fd7fda881ab91f83e509",
    strip_prefix = "bazel-zig-cc-{}".format(BAZEL_ZIG_CC_VERSION),
    urls = ["https://git.sr.ht/~motiejus/bazel-zig-cc/archive/{}.tar.gz".format(BAZEL_ZIG_CC_VERSION)],
)

load("@bazel-zig-cc//toolchain:defs.bzl", zig_toolchains = "toolchains")

zig_toolchains()

And I ran the following command.

 bazel build --platforms @zig_sdk//platform:linux_arm64 --extra_toolchains @zig_sdk//toolchain:linux_arm64_gnu.2.28  --incompatible_enable_cc_toolchain_resolution  //test/banana

Running the command above resulted the following.

I also tried @zig_sdk//toolchain:linux_arm64_musl but nothing worked. I am using a darwin_arm64 machine and every targets of darwin (darwin_arm64, darwin_amd64) works well.
The error messages seem like all standard libraries failed to be linked. Any thoughts?

Thank you!

Here is the crux of the problem: ziglang/zig#9832 (comment)

TLDR: compile your dependencies with zig c++ too.

No easy job there... Thanks a lot!
