Hey all,

I just started using Ogre and I am quite inexpereinced in building c++ files from source. I am getting these errors out of the box with this as my code:

Code: Select all

#include <iostream>
#include "submodules/ogre/sdk/include/OGRE/Ogre.h"
int main(int, char**) {
    std::cout << "Hello, world!\n";
}

Errors:

Anyone have any idea what is going on? Let me know if you need anything else from me. I am on Mac using the most recent version of Ogre.

I figured out the fix to this. The issue is that Mac uses an older version of clang out of the box for some reason which does not support the 'constexpr' keyword. In order to remedy this I had to compile with this argument: "/usr/bin/clang++ -std=c++11" which allows c++11 support.
