Subj : unresolved error with FITS To : borland.public.cpp.borlandcpp From : "Alan Giltinan" Date : Wed Oct 08 2003 02:52 pm Hi all, I have a problem which keeps occuring when i try to build my program. First, the program is used for reading a particular image file called FITS. The 'fitsio.h' file is included without a problem and compiling is no problem. However when i try to build, the following error occurs, "Error: Error: Unresolved external '_ffopen' referenced from D:\CFITSIO\CEXAMPLES\TEST_FITS.OBJ" I suspect it is because i do not have a .lib or .dll file specified correctly but i do not know how to do this. Can anyone help please? thanks -- Yours sincerely, Alan Giltinan, Environmental Monitoring and Space Science Group, Department of Applied Physics and Instrumentation, Cork Institute of Technology, Bishopstown, Cork, Ireland.
