CRC++

CRC++ is a new reference implementation for the CRC algorithm.

Its purpose is to complement Ross Williams famous reference implementation with a modern, template based version written in C++.

Both versions of CRC++ come with a unit test suite. CRC++ version 1.0 requires a working installation of CppUnit in order to run the unit tests. Version 1 will run well with gcc version 2.95 and VC++ 6. To compile successfully under newer compilers (gcc 3 and 4, VC++ 2003 and above), you need version 2. The unit tests of CRC++ version 2.0 are based on CxxTest, which requires no more installation than just copying a bunch of files into your include path.
