Dirk Eddelbuettel: crc32c 0.0.1 on CRAN: New Package


↺ Dirk Eddelbuettel: crc32c 0.0.1 on CRAN: New Package


> Happy to announce a new package: crc32c. This arose out of a user request to add crc32c (which is related to but differnt from crc32 without the trailing c) to my digest package. Which I did (for now in a branch), using the software-fallback version of crc32c from the reference implementation by Google at their crc32c repo.

> However, the Google repo also offers hardware-accelerated versions and switches at run-time. So I pondered a little about how to offer the additional performance without placing a dependency burden on all users of digest.


↺ digest


> Lo and behold, I think I found a solution by reusing what R offers. First off, the crc32c package wraps the Google repo cleanly and directly. We include all the repo code – but not the logging or benchmarking code. This keeps external dependencies down to just cmake. Which while still rare in the CRAN world is at least not entirely uncommon. So now each time you build the crc32c R package, the upstream hardware detection is added transparently thanks in part to cmake. We build libcrc32c.a as a static library and include it in the R package and its own shared library.
