Installation quits: clang not recognizing flags

[sukritsilas]

Trying to install smashpp on MacOSX Mojave 10.14.6 (18G2022). Git (2.26.0) and homebrew (2.2.10) installed already.

clang --version returns:-
Apple LLVM version 10.0.1 (clang-1001.0.46.4)
Target: x86_64-apple-darwin18.7.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

Here's the ouput from running "sudo sh install.sh" or "sudo bash install.sh". The ./ method doesn't work for some reason.

As a quick fix, you can install 'g++'.

With new modifications, you can now compile the code with Clang.
