unresolved external

[infacta]

hi all
i am relatively new to c++ and have run into a problem. I am running a program called cfitsio, used for viewing certain types of images, but when i try to link it i get a error saying
"error: unresolved external '_ffopen' referenced from D:\CFITSIO\IMLIST.OBJ"
I do not know what this error means? can anyone explain what thee error means in general?
Thanks in advance
infacta

you should add some lib files, or implement this function yourself
