@oran-z @SheldonHH the clang you are using is the default Mac installation of clang which is not compiled with RTTI enabled i.e.
oran:~ yaobukeji$ which clang
/usr/bin/clang

Adjusting your PATH to use the brew installation of clang should get you what you need i.e.
export PATH=/usr/local/bin:$PATH

@oran-z Try this

For v1.5.0, the following works for me:
brew install --with-clang --with-lld --with-python llvm@4
export PATH=/usr/local/Cellar/llvm@4/4.0.1_1/lib/cmake/llvm; ./eos_build.sh -s 'EOS'
