Bindgen Invocation

bindgen::Builder::default()
	.header("wrapper.hpp")

Actual Results

The following warnings were emitted during compilation:

warning: couldn't execute `llvm-config --prefix` (error: No such file or directory (os error 2))
warning: set the LLVM_CONFIG_PATH environment variable to the full path to a valid `llvm-config` executable (including the executable itself)

Expected Results

I expected no fatal error.

This has happened on every single clang on my macOS 10.14.6 system, even if I try to specify include paths and stuff. Also it's really weird. Look here:

Nope. Surely it must not work right?

It does. However, with all the extra flags added by bindgen it doesn't:

So telling bindgen not to add those flags should work then, right?

Repro here https://github.com/LoganDark/bindgen-hates-macos if anyone has a macOS 10.14 machine.

kulp · 2020-07-22T11:55:44Z

I easily reproduced this on my macOS 10.14.6 machine.

cd $(mktemp -d)
git clone https://github.com/LoganDark/bindgen-hates-macos.git
cargo test

I do not know anything further at this time. I might be able to look at this on Friday.

LoganDark · 2020-07-22T15:29:58Z

Yesss, thank you!

LoganDark · 2020-07-25T10:16:37Z

Hey, any progress on this? Still impacted by this issue.

kulp · 2020-07-26T22:29:32Z

I looked at this a little while longer.

I agree that this particular problem should not arise (#1597 implies that #include <string> works on non-macOS platforms).

I was able to work around the issue for your particular testcase by adding these two lines before .generate():

.clang_arg("-I/Library/Developer/CommandLineTools/usr/include/c++/v1")
.clang_arg("-I/Library/Developer/CommandLineTools/usr/lib/clang/10.0.1/include")

(the first arg for <string> and the second for <stdarg.h>).

I understand that this is not really a solution, but I have no experience using bindgen with C++, so I am not likely to be much more help myself. Perhaps @emilio has seen something like this before.

LoganDark · 2020-07-26T23:51:02Z

Well, bindgen already tries to detect include paths so I suppose it should know this already.

It is too a solution, but one I shouldn't have to apply myself. bindgen should understand that these options are necessary (in that order too) and automatically apply them. Either that, or it should invoke the compiler in such a way that these options are not necessary to explicitly provide (maybe not possible with libclang, I'm not sure).

LoganDark · 2020-07-27T05:02:20Z

So it seems like the solution is specifying /Library/Developer/CommandLineTools/usr/include/c++/v1 before the other include paths - since stuff uses #include_next, the included file has to exist after that file in the include chain, not before. That's hilarious, because bindgen seems to just throw flags around carelessly.

This could probably be fixed by bindgen automatically finding the STL and including it first in the include chain. That solution is cross-platform and could also be preventative towards other, unforeseen issues.

similar problem on nixos linux
i must set include paths for bindgen::Builder::default() in c2rust-ast-exporter/build.rs

    let cppbindings = bindgen::Builder::default()
        .header("src/ExportResult.hpp")
        .whitelist_type("ExportResult")
        .generate_comments(true)
        .derive_default(true)
        // Tell bindgen we are processing c++
        .clang_arg("-xc++")
        .clang_arg("-std=c++11")

        // NixOS workaround to find header files
        // https://github.com/rust-lang/rust-bindgen/issues/1834
        // c2rust/c2rust-ast-exporter/src/ExportResult.hpp:11:10: fatal error: 'algorithm' file not found
        .clang_arg(format!("-I{}/c++/v1", env::var("LIBCXX_INCLUDE_DIR").unwrap()))
        // /nix/store/fpnnmg22plmha1qsq1fvsjsar3ziz2k1-libcxx-7.1.0-dev/include/c++/v1/__config:206:12: fatal error: 'features.h' file not found
        .clang_arg(format!("-I{}", env::var("GLIBC_INCLUDE_DIR").unwrap()))
        // /nix/store/fpnnmg22plmha1qsq1fvsjsar3ziz2k1-libcxx-7.1.0-dev/include/c++/v1/cstddef:44:15: fatal error: 'stddef.h' file not found
        .clang_arg(format!("-I{}", env::var("LIBC_INCLUDE_DIR").unwrap()))

        .generate()
        .or(Err("Unable to generate ExportResult bindings"))?;

# default.nix
{
  preBuild = ''
    export LIBCLANG_PATH=${pkgs.libclang.lib}/lib
    export LIBCXX_INCLUDE_DIR=${pkgs.libcxx.dev}/include
    export GLIBC_INCLUDE_DIR=${pkgs.glibc.dev}/include
    export LIBC_INCLUDE_DIR=${pkgs.libclang.lib}/lib/clang/7.1.0/include
  '';

This PR replaces an unmaintained fork of secp256k1 to the latest version of the original library that already have all required features with a more clear API. Also this will solve compilation issues with llvm 13.* tools on MacOS like the next: rust-lang/rust-bindgen#1834

levkk · 2023-05-01T17:34:46Z

I hit this on Linux (Ubuntu) as well. I ended up manually adding:

#[cfg(target_os = "linux")]
let bindings = bindings
    .clang_arg(format!("-I/usr/include/c++/11"))
    .clang_arg(format!("-I/usr/include/x86_64-linux-gnu/c++/11"));

to my build.rs.

spacejam · 2024-10-16T10:01:10Z

I hit this on macos after a system update seems to have broken my non-app-store-installed copy of xcode. I realized I could work around it by setting export CPPFLAGS="-I/Library/Developer/CommandLineTools/SDKs/MacOSX14.5.sdk/usr/include/c++/v1/" (a directory that contains iostream and string etc... on my system), but then I seem to have fixed it without explicitly setting that env var by going into the xcode Settings GUI, going to the "Locations" tab, and even though Command Line Tools already listed Xcode 16, when I clicked its drop down (there was only one option for me) and I re-selected it, it asked me to authenticate, and then suddenly the system started working again. Before explicitly clicking this, xcode-select --print-path printed out /Library/Developer/CommandLineTools, but after this reconfiguration it printed out /Applications/Xcode.app/Contents/Developer, and then compilation started working as expected without the env var workaround. Hope this helps somebody!
