Yes: Read the error message and analyze the code.
#if defined(_RWCONFIG_12d)// <== not defined !!!
#include "rwc_tls_12d.h"
#elif defined(_RWCONFIG_15d) // <== not defined !!!
#include "rwc_tls_15d.h"
#else
#error "No _RWCONFIG_<tag> found" // <== your output
#endif
Conclusion: you must decide whether to use the version 1.2 or 1.5 of that framework, with
#define _RWCONFIG_15d 1
or in the project settings of C++ in some header before including this problematic code.
