Looks like an old version of C++ compiler that we need for spirv_cross. What is your clang/gcc version?

oncealong commented 5 years ago

clang

I install XCode 10 and XCode 9.

Apple LLVM version 9.1.0 (clang-902.0.39.2)
Target: x86_64-apple-darwin18.0.0
Thread model: posix
InstalledDir: /Applications/Xcode_9.4.1.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

Hello @oncealong . We are hiring full-time gfx-hal based project developers. We have both Beijing and Shenzhen offices. Feel free to contact me. See my GitHub info.

grovesNL commented 5 years ago

@oncealong Is that the output of clang --version or c++ --version? Could you try which c++ and c++ --version?

I'm getting the same error with the newer versions of clang/osx:

OSX 10.14.5

-rwxr-xr-x  1 root  wheel  18304 May  4 00:04 /usr/bin/clang++

Is it possible that isn't the version of clang that the compiler is actually using internally?

chrisburnor commented 5 years ago

I think I found the root of the issue.

In https://github.com/alexcrichton/cc-rs/blob/master/src/lib.rs#L2113, cc, looks at the compiler name to determine the type and falls back to gnu if none match.

For myself and @oncealong , where c++ is symlinked to clang++ it looks like cc doesn't follow the symlink and, so, falls back to gnu.

Prepending CXX=$(which clang++) to the command fixes the issue:

% CXX=$(which clang++) cargo run --bin quad --features metal

Filed https://github.com/alexcrichton/cc-rs/issues/408 in cc to track downstream bug.
