CRoaring is a C11-compliant library providing compressed Roaring bitmaps. CppRoaring4VS provides a C++ wrapper for Microsoft Visual Studio 2015.
CRoaring: https://github.com/RoaringBitmap/CRoaring
The primary goal of the CRoaringVS is to provide a static library that can be used in Microsoft Visual Studio 2015 compiled projects.
- Microsoft Visual Studio 2015 Community Edition update 3 or better.
- Within Visual Studion, have "Clang with Microsoft CodeGen" installed (found under Cross Platform Mobile Development / Visual C++ Mobile Development in the Modify features list).
Load msv/CRoaringVSLib.sln into Microsoft Visual Studio. The project should then build both the library and small test program that you can run.
- Microsoft Visual Studio 2015 does not support Intel intrinsics thus we have to disable several optimizations (such as AVX2 support). A bug has been submitted: https://connect.microsoft.com/VisualStudio/feedback/details/3102596/clang-c2-intel-intrinsics-support-for-clang
- Sources: The original amalgamated CRoaring source files can be found in the directory src/croaring. The c++ header file for this library in the directory inc. The c++ implementation file for this library in the directory src. The source file for the test is in the directory tst.
- Project files: The Microsoft Visual Studio 2015 solution file is available in the directory msv. This solution contains the following 2 projects each in its own subdirectory: CRoaringVSLib (to build the library), CRoaringVSTest (to test the CRoaringVSLib library).
- Library files The static .lib files are in the lib directory.
- Consider disabling Intellisense since it can't parse standard compliant C code: Tools -> Options -> Text Editor -> C/C++ -> Advanced, and set Disable Error Reporting to True.
- Once you have a clang CodeGen project, you can go under Configuration Properties, C/C++, Language, C Language Standard and choose between C89, C99, C11, C99 GNU, C11 GNU.
