macos: `ld: library not found for -lstdc++` when compiling `no_deps` example #247

Building a fresh checkout of examples/remote/no_deps with Bazel 3.6.0 fails on MacOS with the error:

pandas-dev/pandas#23424 (comment) may be relevant.

nikclayton-dfinity · 2020-10-13T14:48:25Z

https://developer.apple.com/documentation/xcode-release-notes/xcode-10-release-notes?preferredLanguage=occ suggests that on recent OSX libstd++ is no longer supported and libc++ should be used instead.

nikclayton-dfinity · 2020-10-13T14:54:18Z

bazelbuild/rules_rust#226 is probably the real bug here.

nikclayton-dfinity · 2020-10-14T07:40:30Z

Add this to the bottom of the WORKSPACE file:

# Everything below here is key to building on OSX. Load a custom Clang
# toolchain rather than whatever happens to be installed on the machine.
#
# The entry in .bazelrc automatically selects this toolchain for building.
http_archive(
    name = "com_grail_bazel_toolchain",
    url = "https://github.com/grailbio/bazel-toolchain/archive/0.5.6.zip",
    sha256 = "759e6c10e7883b5969db01b5bdb01c5518bcf7ae637972d5a109eb994a669487",
    strip_prefix = "bazel-toolchain-0.5.6",
)

load("@com_grail_bazel_toolchain//toolchain:deps.bzl", "bazel_toolchain_dependencies")
bazel_toolchain_dependencies()

load("@com_grail_bazel_toolchain//toolchain:rules.bzl", "llvm_toolchain")
llvm_toolchain(
    name = "llvm_toolchain",
    absolute_paths = True,
    llvm_version = "9.0.0",
)

load("@llvm_toolchain//:toolchains.bzl", "llvm_register_toolchains")
llvm_register_toolchains()

and create .bazelrc in the same directory as the WORKSPACE file with the following contents:

build --crosstool_top=@llvm_toolchain//:toolchain

Then everything works for the no_deps example.

nikclayton-dfinity · 2020-10-14T07:42:34Z

complicated_cargo_library also works.

nikclayton-dfinity · 2020-10-14T07:58:34Z

non_cratesio doesn't.

It builds, but running it produces no output.

However, running it with Cargo has the same problem:

so I'm not sure what's going on there.

Without digging too deeply, is this a bug in cargo-raze or in rules_rust? (as per #247 (comment))

nikclayton-dfinity · 2020-10-21T13:39:19Z

The primary bug is in rules_rust.

I think there's probably two bugs in the cargo-raze examples.

They don't work out of the box on macOS, you need to do bazel build //... fails on OSX bazelbuild/rules_rust#226 (comment) in the WORKSPACE file.

The most version I have of those additions is:

    name = "llvm_toolchain",
    absolute_paths = True,
    llvm_version = "10.0.0",
)

load("@llvm_toolchain//:toolchains.bzl", "llvm_register_toolchains")
llvm_register_toolchains()

non_cratesio producing no output irrespective of how it's built (macos: ld: library not found for -lstdc++ when compiling no_deps example #247 (comment)).

UebelAndre · 2020-10-21T14:47:11Z

1. They don't work out of the box on macOS, you need to do [bazelbuild/rules_rust#226 (comment)](https://github.com/bazelbuild/rules_rust/issues/226#issuecomment-626378800) in the `WORKSPACE` file.

Odd, I'm able to build the examples on MacOS just fine. Perhaps the rust rules are relying on some specific machine setup. It might be good to open a pull request to rules_rust making it's tooling more explicit so users see consistent behavior regardless of how their machines are configured (if that is indeed the case here).

2. `non_cratesio` producing no output irrespective of how it's built ([#247 (comment)](https://github.com/google/cargo-raze/issues/247#issuecomment-708230957)).

Interesting, seems to me like env_logger wasn't setup correctly? It does seem to be though. From some quick tests it doesn't seem like the logger is initializing to log Info level logs. Adding the following always panics

if !log_enabled!(log::Level::Info) {
  panic!("uh-oh");
}

This should definitely be looked at and updated. I may take a stab at it when I can find the time.

Sorry this isn't much help. But it's good to know where the issue is. You should chime in on bazelbuild/rules_rust#226 and let the owners know users are still running into that issue 😄

For folks experiencing ld: library not found for -lstdc++, this is a bug in bazel I've submitted a patch for, for more details see bazelbuild/bazel#14395 (comment)

This flag has been invalid seemingly since macOS 10.9 from 2013. By default clang remaps this back to -lc++, but if your linkopts pass -nodefaultlibs this is not the case, in which case this invalid flag fails the link. This happened for rust builds where the rust driver passes this flag intentionally. For more info see #14395 (comment) Fixes google/cargo-raze#247 #14395 bazelbuild/rules_rust#226 Closes #14542.

PiperOrigin-RevId: 424588734 (cherry picked from commit 8b60c90)

This flag has been invalid seemingly since macOS 10.9 from 2013. By default clang remaps this back to -lc++, but if your linkopts pass -nodefaultlibs this is not the case, in which case this invalid flag fails the link. This happened for rust builds where the rust driver passes this flag intentionally. For more info see #14395 (comment) Fixes google/cargo-raze#247 #14395 bazelbuild/rules_rust#226 Closes #14542.
