Hi.
I have a C program that I need to compile.
The problem is that it has alot of callback functions.
The code compiles Ok, but on linking stage I'm getting alot of
'undefined reference' error.
How can I avoid that?
Is there some switch to turn that check off?
Thanks.

When trying to compile using gcc on an intel box running Redhat Linux, I
get the following errors:
Linking...
getf.o: In function `get_fits':
/usr/src/getflat/getf.c:124: undefined reference to `usr_imagein'
/usr/src/getflat/getf.c:134: undefined reference to `rfts_data'
getf.o: In function `write_fits':
/usr/src/getflat/getf.c:143: undefined reference to `usr_imageout'
/usr/src/getflat/getf.c:145: undefined reference to `wfts_data'
/usr/src/getflat/getf.c:151: undefined reference to `wfts_char'
/usr/src/getflat/getf.c:156: undefined reference to `wfts_real'
collect2: ld returned 1 exit status
make: *** [getf] Error 1
These are all functions related to reading/writing FITS files and are
declared in header files which are included at the start of the program.
I'm linking using -lm -luti -lcfitsio -lX11.
libutil.a,libuti.a and libcfitsio.a all seem to be installed fine.
The program compiles fine on an Alphastation running Digital UNIX.
I don't know if there are just some other libraries I need to install?
Cheers
Ali
