Does compiling any Rust project work with Clang 10.0 on your system?

@iSynaptic yes,i compiling https://github.com/KZen-networks/gotham-city/tree/master/gotham-client
,that ok,but only compiling librocksdb-sys fail

@freehere107 Strange. We've got a CI build that ensures it compiles on Mac OS. I'm wondering if there is some tooling version incompatibilities causing this. I don't have access to a Mac - is it possible for you to try an earlier version of Clang to see if that is where the incompatibility is coming from?

@iSynaptic ok. i try it, thank you

@freehere107 Did a different version of Clang work?

@iSynaptic Still have same error.i reopen this issue

@aleksuss I'm not using a Mac for my workstation, are you? If so, are you able to reproduce this?

Cannot reproduce. The exact same Mac version, clang and rustc versions

@vitvakatu Thanks!

@freehere107 Our Mac CI build and @vitvakatu's Mac cannot reproduce. I'm going to close for now, but if you can pinpoint what might be causing the error for you, please post the details here.

@iSynaptic I can't reproduce it as well 😕

I try reinstall llvm, it solved, brew upgrade llvm
