This page will attempt to describe features of modern C++ standards (C++11, C++14, etc.) supported by the game. For information on building the game, see BuildInstructions.

Supported Compilers

0 A.D. is a cross platform game written primarily in C++ and JavaScript, and as such it has to support multiple compilers with different implemented features. Here are the currently supported compilers for the game:

  • GCC 4.8.1 or newer
  • Clang 3.4 or newer
  • Visual Studio 2013

The following tables summarize C++11 support for the above compilers. Features available (Y) in all supported compilers are marked green and believed safe to use. Features not available (N) in all supported compilers are marked red and generally should not be used in 0 A.D. In a few cases there is partial support (P), these rows are yellow.

Code examples are given for many features as the formal names can be unclear.
