Hello everyone,

I’m trying to extract the _year, month, day, hour, minute, second and  
millisecond_ from an std::chrono::time\_point object in my OOT module,  
but  
when I try compiling it, it gives me an error as the title suggests.  
Then  
it says: “It must be enabled with the -std=c++11 or -std=gnu++11  
compiler  
options”.

My question is, how do I enable this support?

Best,  
Ali

You can enable it in you CMakeLists.txt
