Runtime error

[BrinthaVP]

Hi,

I am trying to use numpy_random library for my project. But facing some issues.

First I build the code using the command cmake CmakeFiles.txt and then copied the src/numpy_random.h to the directory that contains the code in the sample in a file trial.cpp.

I ran the trial.cpp using the command g++ -L "/data/users/numpy_random" -std=c++11 trial.cpp

But I am getting errors like this:

'''

By passing the argument -std=c++11, you are instructing GCC to use C++ 11. However, in order to compile it, you will need to use the appropriate compiler flags or options to use C++ 17.
