Hi Amadio, I have used a binary version of ROOT on my mac os laptop, however while I am trying to cmake my native ROOT project with g++-8, I got compiling errors about '-Qunused-arguments, if I cmake it with clang/clang++, I got errors about std::basic_string as you mentioned above. And this native package could be well compiled with g++ on ubuntu system. I pasted the errors for g++-8 and clang below separately. Is there any way to bypass this?
