Hi, I had the same issue, and I manage to solve it with the following steps
- sudo apt-get install build-essential clang-3.9 git cmake ninja-build python3-requests python-dev tzdata sed curl wget unzip autoconf libtool
- sudo update-alternatives --install /usr/bin/clang++ clang++ /usr/lib/llvm-3.9/bin/clang++ 100
- sudo update-alternatives --install /usr/bin/clang clang /usr/lib/llvm-3.9/bin/clang 100
- run ./Setup.sh again
Hope this helps
