Created Unassigned: build error on Mac 10.10 [310]

I have met these errors when I build it on my mac:

/Users/liuzhn/Projects/odatacpp/odatacpp/lib/casablanca/Release/libs/websocketpp/websocketpp/common/network.hpp:53:17: error: expected ')'
inline uint64_t htonll(uint64_t src) {


/Users/liuzhn/Projects/odatacpp/odatacpp/lib/casablanca/Release/libs/websocketpp/websocketpp/common/network.hpp:74:17: error: expected ')'
inline uint64_t ntohll(uint64_t src) {


Is there anything I missed?

Thanks!
