Question on mixing ESQL/C and C++

Hi, Does anyone out there have experience mixing ESQl/C and C++? The only instruction that I have is an old tech bulletin from Informix. I am running Online version 7.10 with ESQL version 7.1. The tech bulletin says something about creating a header file with all of the Informix library functions declared as prototypes. I tried this and keep geetting symbol refernce errors. See below. If anyone can shed some light on this I would really appreaciate it! Thanks, Bill ------------------- Undefined first referenced symbol in file _iqnprep(char*, char*) guif_table.o sqlca guif_table.o _iqclose(_sqcursor*) guif_table.o _iqdcopen(_sqcursor*, sqlda*, char*, value*, int, int) guif_table.o _iqcddcl(_sqcursor*, char*, _sqcursor*, int) guif_table.o _iqdbclose(void) guif_table.o _iqcftch(_sqcursor*, sqlda*, sqlda*, char*, _FetchSpec*) guif_table.o load_db_tables main.o _iqdbase(char*, int) guif_table.o _iqlocate_cursor(char*, int) guif_table.o strcpy(char*, const char*) guif_table.o ld: fatal: Symbol referencing errors.
