Running Source Code on your own machine

All source code examples are complete; that means, assuming you have a conforming compiler, you can compile and run them. The name of the source file is in the title of the listing. Only, if necessary, will I use the using namespace std directive in the source files.

Run the Programs

Compiling and running the examples is quite easy for the C++11 and C++14 examples in this course. Every modern C++ compiler should support them. For both the GCC and the clang compiler, the C++ standard must be specified as well as the threading library to link against. For example, the g++ compiler from GCC creates an executable program called thread with the following command-line: g++ -std=c++14 -pthread thread.cpp -o thread.

• -std=c++14: use the language standard C++14
• -pthread: add support for multithreading with the pthread library
• thread.cpp: source file
• -o thread: executable program

The same command-line works for the clang++ compiler. The Microsoft Visual Studio 17 C++ compiler supports C++14 as well. If you have no modern C++ compiler at your disposal, there are a lot of online compilers available. Arne Mertz’ blog post C++ Online Compiler gives a great overview.

With C++17 and C++20, the story becomes quite complicated. I installed the HPX (High-Performance ParalleX) framework, which is a general purpose C++ runtime system for parallel and distributed applications of any scale. HPX has already implemented the Parallel STL of C++17 and many of the concurrency features of C++20. Please refer to the corresponding sections in the chapter The Future: C++20, and read about how you can see the code examples in action.
