+ should be compiled. <b>cds</b> depends on C++ standard library only.
- External dependenies: the tests depends on:
+ Test suite depends on:
- \p boost.thread (thread-loal storage support), boost.system
- \p google-test
+ Some parts of libcds may depend on DCAS (double-width compare-and-swap) atomic primitive if
+ the target architecture supports it. For x86, cmake build script enables -mcx16 compiler flag that
+ switches DCAS support on. You may manually disable DCAS support with the following command line flags

+ - \p -DCDS_DISABLE_128BIT_ATOMIC - for 64bit build
+ - \p -DCDS_DISABLE_64BIT_ATOMIC - for 32bit build
+
+ @warning All your projects AND libcds MUST be compiled with the same flags - either with DCAS support or without it.

\par Windows build
Prerequisites: for building <b>cds</b> library and test suite you need:
- <a href="http://www.boost.org/">boost library</a> 1.51 and above. You should create environment variable
\p BOOST_PATH containing full path to \p boost root directory (for example, <tt>C:\\libs\\boost_1_57_0</tt>).
- Open solution file <tt>cds\projects\vc14\cds.sln</tt> with Microsoft VisualStudio 2015.
+ Open solution file <tt>cds\projects\vc141\cds.sln</tt> with Microsoft VisualStudio 2017.
The solution contains \p cds project and a lot of test projects. Just build the library using solution.
<b>Warning</b>: the solution depends on \p BOOST_PATH environment variable that specifies full path
to \p boost library root directory. The test projects search \p boost libraries in:
- for 32bit: <tt>\$(BOOST_PATH)/stage/lib</tt>, <tt>\$(BOOST_PATH)/stage32/lib</tt>, and <tt>\$(BOOST_PATH)/bin</tt>.
- for 64bit: <tt>\$(BOOST_PATH)/stage64/lib</tt> and <tt>\$(BOOST_PATH)/bin</tt>.
-
+
All tests are based on googletest framework. The following environment variables specify
where to find gtest include and library directories:
- \p GTEST_ROOT - gtest root directory. <tt>\$(GTEST_ROOT)/include</tt> specifies full path to
For Unix-like systems GCC and Clang compilers are supported.
Use GCC 4.8+ compiler or Clang 3.6+ to build <b>cds</b> library with CMake.
See accompanying file <tt>/build/cmake/readme.md</tt> for more info.
-
- @note Important for GCC compiler: all your projects that use \p libcds must be compiled with <b>-fno-strict-aliasing</b>
- compiler flag.
