You have to tell the C++ compiler that you are using C code: #ifdef __cplusplus extern "C" { #endif }#include <decimal.h> #ifdef __cplusplus } #endif }main() }{ } double dbl_val; } dec_t dec_val; } int ret_val; } ret_val = dectodbl(&dec_val, &dbl_val); }} } }dectodbl seems to be undefined when using a C++ compiler. Works fine }if I use the c compiler. Older versions of informix did not seem to }have this problem.
