Software Technology Lab Concurrency Library

Requirements

  • C++ 14 compatible compiler

    • Visual Studio 2015 Update 5 or later
    • Clang 3.8 or later
    • GCC 4.8.5 or later

  • boost.optional, boost.variant (only for C++14, see below for further details)

  • boost.test (only for the unit tests)

Configuration Options

The concurrency library is a header only library. Add ./ to the include path. It is necessary to add the compiler flag -fpermissive for all gcc versions < 7, because of a gcc bug. The compiler complains about a static constexpr statement in the stlab::task class. It accepts the code with the -fpermissive flag, but the compiler produces a huge ammount of warnings, that can only be silenced with -w flag.

The library uses per default boost::optional and boost::variant.

Under certain conditions, it uses different implementations for optional in the following order:

  • boost::optional, if the define STLAB_FORCE_BOOST_OPTIONAL is set, or
  • std::optional, if C++17 is enabled and std::optional is available, or
  • std::experimental::optional, if it is available, otherwise
  • boost::optional

Under certain conditions, it uses different implementations for variant in the following order:

  • boost::variant, if the define STLAB_FORCE_BOOST_VARIANT is set, or
  • std::variant, if C++17 is enabled and std::variant is available, or
  • boost::variant
