Hi Tom, Unfortunately, I believe the C client was a project that was started with the intention of knocking down two birds with one stone, official support for C and wrap it as a C extension for PHP. The project has not been updated in about a year, while other clients have seen a lot of updates in that time.
I'm aware that we do not have any Basho resources towards moving this client forward in the near future, which leaves me with essentially three options: 1) Submit GH issues for each problem you encounter we can try to queue up time to review them. 2) Submit contributions to the project by fixing the issues and submitting a PR for each fix. 3) If time is of the essence, consider using one of our officially supported clients [1] or this C client that seems to have some recent momentum [2] [1] http://docs.basho.com/riak/latest/dev/using/libraries/ [2] https://github.com/algernon/riack I hope this helps.
