I am using xCode with cplex (following this tutorial http://www.leandro-coelho.com/how-to-configure-ibm-cplex-with-apple-xcode/) when I change c++ standard library to libstdc++ (GNU c++ standard library) I am no longer able to use arrays (include says not found) when I switch back libc++ (LLVM standard library with c++ 11 support) include works fine but not cplex.

thank you for your help !
