I am facing the problem of calling cfitsio library from C program in linux. when i am giving
the option "gcc -o CreateLevel1DataFitsFile CreateLevel1DataFitsFile.c -lm -lcfitsio
"
i am getting following error

The highlighted line above implies that this isn't the very first error message you're getting. Dealing with anything but the first error you get is generally (pretty much always) a complete waste of time - could you post the first error? (or the complete output, if you're not sure where the first error is).
