This file describes how to install a new version of CFITSIO in TABLES.
CFITSIO can be obtained from the High Energy Astrophysics Archive Research
Center, HEASARC:
http://heasarc.gsfc.nasa.gov/fitsio
The directory containing CFITSIO in the TABLES package is:
tables$lib/tbtables/cfitsio/
Before installing a new version, save the mkpkg file from the above
directory, since a new distribution may include a file with the same
name but with very different contents.
After saving mkpkg, the files in the distribution can then be installed
in tables$lib/tbtables/cfitsio/. Copy the saved version of mkpkg into
this directory, clobbering the version from the distribution. This saved
version of mkpkg may need to be modified to include new files, as described
below.
These are the files that may need to be modified (unless these changes
have been incorporated into future versions of CFITSIO):
eval_l.c
fitsio2.h
Changes to eval_l.c and fitsio2.h:
On a VMS machine, if the linker gives an error about strcasecmp and
strncasecmp being redefined, remove vms and __vms from this section
(this is near the end of both files):
#if defined(vms) || defined(__vms) || defined(WIN32) || defined(__WIN32__) || defined(macintosh)
/* ================================================================== */
/* A hack for nonunix machines, which lack strcasecmp and strncasecmp */
/* ================================================================== */
changing it to this:
#if defined(WIN32) || defined(__WIN32__) || defined(macintosh)
/* ================================================================== */
/* A hack for nonunix machines, which lack strcasecmp and strncasecmp */
/* ================================================================== */
Changes to mkpkg:
There will be files in the CFITSIO distribution that are not needed by
the TABLES library, such as test programs; these should not be included
in mkpkg. However, there may be new source files that contain functions
that are called by functions that are called by the table I/O routines.
If the link fails for the ttools package, find the source files containing
the missing modules, and add these files to the list of dependents in mkpkg
for libtbtables.a. It may require more than one iteration to find all the
required source files.
