Check the following threads:

• https://forums.developer.apple.com/thread/104296.
• Source Cpp file failed due to math.h not found RcppCore/Rcpp#922

In short, XCode not provide /usr/include by default anymore since Mojave.
You just need to install the following package manually, and the bug should
be gone.

/Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14. pkg

@fujimotos , Thank you! I will try and get back..

Note : For people who want to install fluent-bit on mac, brew install fluent-bit works.. This issue is only when compiling the source code.
