I’ve just released simple C++ static library bfx-cpp-api which interfaces Bitfinex REST API (Websocket interface coming soon). Bfx-cpp-api uses libcurl and cryptopp library which must be installed before use. Check example code and don’t forget to link to libcurl and cryptopp when compiling.
Before using authenticated endpoints be sure you have created API-secret-key file where first line is API access key and second line is API secret key.
