Caution for compiling with cfitsio library
[All of Data Analysis System(Servers and Terminals)]
[Data analysis servers(anam* and anah*)]
[Terminal Workstations(alws* and sbws*)]
Compiling programs with cfitsio library may fail.
(Example) compress_fits URL: http://heasarc.gsfc.nasa.gov/docs/software/fitsio/cexamples.html ========= cc -I/usr/local/include -L/usr/local/lib -o compress_fits compress_fits.c -lcfitsio -lm /var/tmp/ccSFbWKg.o: In function `main': compress_fits.c:(.text+0x489): undefined reference to `fits_comp_img' collect2: ld returned 1 exit status =========
This failure is caused by that the function "fits_compress_img" was not used since 27 April, 2011.
Instead of this, you can use the function "fits_img_compress" that has equivalent capability to "fits_compress_img".

This routine is obsolete and should not be used. The
ftools 'fimgzip' task used to call this routine (but that task has been deleted);
The name of the routine was changed 4/27/2011, to see if anyone complains.
If not, then this routine should be deleted from the source code.

This routine initializes the output table, copies all the keywords,
and loops through the input image, compressing the data and
writing the compressed tiles to the output table.
