C++ 11 standard library implementation with extra features using C++98 only and POSIX threads. Minimum ugly preprocessor macro and no configuration files. The library itself is built on top of C++ standard library distributed with your compiler and just extends it with C++11 features.

Usage examples on Wiki

Supported platforms

  • Windows (from XP to 10)
  • Unix (any with glibc and pthread)
  • MacOS (any)
  • QNX 6.x.x
  • QNX 4 (partly)

Wiki for more details.

Q: Why not Boost?

A:

  1. Because I can.
  2. Because I need something without such overhead and ugliness (ugliness and beauty actually, I am really amazed by how Boost handles some features of C++).
  3. Because I want all of basic little helpful classes and tricks (as countof f.e.) be in one place with power of C++ 11 threads handling and template-programming.
C++ 11 implemented features list

Language core

  • nullptr and stdex::nullptr_t
  • static_assert or STATIC_ASSERT macro
  • stdex_char16_t and stdex_char32_t (as equivalent to char16_t, char32_t)
  • stdex_noexcept (as partial equivalent to noexcept)
  • stdex_assert macro (as equivalent to cassert macro)
  • move semantic is in progress

Not all features of C++ 11 can be implemented without compiler support so I have no plans to include such features in the library.

The library is portable for any compiler that supports C++98 but as we all know there are lots of different implementations of std library in even major compilers so this library is tested with:

  • Borland C++ Builder 6.0 Updt4;
  • qcc (just a wrapper over gcc in QNX)
  • g++ 3.4, 4.4.2, 4.4, 4.6;
  • g++ 4.8, 4.9, 5.0 with c++98 option;
  • clang 3.5, 5.0 with c++98 option;
  • clang-900.0.37 with c++98 option (Mac OS);
  • Visual Studio 2008, 2010, 2013, 2015, 2017;

...and that's it. If you use other compilers and decide to include this library in your project there is no guarantee that it will compile without errors. In case you will be able to fix the errors without breaking existing code for already supported compilers I would really appreciate your pull requests.

For the C++ threads (mutexes, threads) I'm using POSIX threads implementation. There is one for Windows platform and definitely should be one for every POSIX-friendly platform.

The library is in development so no backward compatibility guaranteed with previous versions of stdex. But one thing for sure: it will be more and more standard in the way of std library for C++ 11.

how to build

Build process is simple:

  • For Unix - either run a build_lib.sh script (works with g++ and clang if environment variable $COMPILER is set to compiler name, f.e. to clang++-3.5) or build by yourself static library from stdex/src directory sources.
  • For Windows
    • run a build_lib.bat script that works with Visual Studio's cl if environment variables are set by v{s/c}vars{32/64/all}.bat (vcvars32.bat, vsvars32.bat etc.) script that is in your Visual Studio distributive;
    • run a build_lib_bcc32.bat script for Borland C++ Builder 6.0 Updt4 bcc32 build;
    • ...or build by yourself the static library from stdex/src and pthreads-win32 directories sources.
  • For QNX 6.x.x - either run a build_lib_qnx.sh (using qcc compiler) or build by yourself the static library from stdex/src directory sources (do not forget to link with stdlib library).
  • For Mac OS - either run a build_lib.sh script (works with clang if environment variable $COMPILER is set to compiler name, f.e. to clang++-3.5) or build by yourself static library from stdex/src directory sources.

how to include in your project

In your project:

  1. include sources of the library or link with prebuild static library (.a/.lib file, f.e. libstdex.a/stdex.lib)

  2. link with system libraries for POSIX-threads and real-time clocks:

    • librt.lib and libpthread.lib for UNIX;
    • ntdll.lib and POSIX-threads lib for Windows (if you have built stdex static library with pthreads-win32 sources then you have no need to link with pthreads anymore - it's already in stdex.lib);

    Note: ntdll.lib is not present in Borland C++ Builder 6.0 Updt4 so you should make one with coff2omf.exe utility (located in "Borland\CBuilder6\Bin" folder) from Windows SDK/Windows Kit version of ntdll.lib.

    • m.lib for QNX 6.x.x;
    • libpthread.lib for Mac OS;
