C and ESQL problem
Hello, I have some errors building a C program that uses the Informix database. I am using WindowsNT and MS Visual C++. I do not have sufficient programming background to debug the program. Can anyone help me? I have attached the build errors. Any help would be most appreciated, thanks in advance...

Did you use the esql script (hmm maybe it's an executable on NT) to link or did you try to link by hand using link or cc? Looks like none of the Informix libraries were included in the link. Use esql to link and the problem goes away. Art S. Kagel Andrew Smith wrote: > > Hello, > > I have some errors building a C program that uses the Informix database.
