To build and install CCfits  from source code on a UNIX-like (e.g. UNIX,
Linux, or Cygwin) platform, take the following steps.  For building on
a Microsoft Windows platform with Visual Developer Studio, see below.

===============================================================================
Instructions for Building CCfits on UNIX-like platforms:
===============================================================================

1. Configure
 
   By default, the GCC compiler and linker will be used.  If you want to
   compile and link with a different compiler and linker, you can set
   some environment variable before running the configure script.  For
   example, to use Sun's C++ compiler, do the following:

   > setenv CXX CC  (csh syntax)

     or

   > export CXX=CC  (bash syntax)

   You can set the absolute path to the compiler you want to use if necessary.

   CCfits requires that the CFITSIO package, version 3.08 or later, is
   available on your system.  See

     http://heasarc.gsfc.nasa.gov/docs/software/fitsio/fitsio.html

   for more information.  The configure script that you will run takes an
   option to specify the location of the CFITSIO package.

   If the CFITSIO package is installed in a directory consisting of a
   'lib' subdirectory containing "libcfitsio.a" or "libcfitsio.so" and
   an 'include' subdirectory containing "fitsio.h", then you can run the
   configure script with a single option.  For example, if the cfitsio
   package is installed in this fashion in /usr/local/cfitsio/ then the
   configure script option will be

	--with-cfitsio=/usr/local/cfitsio

   If the CFITSIO package is not installed in the above manner, then you
   need to run the configure script with two options, one to specify the
   include directory and the other to specify the library directory.  For
   example, if the cfitsio package was built in /home/user/cfitsio/ then
   the two options will be

	--with-cfitsio-include=/home/user/cfitsio 
	--with-cfitsio-libdir=/home/user/cfitsio

   For users of HEASOFT (instead of stand-alone CFITSIO):
   Note that modern distributions of HEASOFT only include a
   "libcfitsio_X.XX.so" library by default, but the configure script
   needs to find "libcfitsio.so", so you will need to create a symbolic
   link in $HEADAS/lib/ linking libcfitsio.so -> libcfitsio_X.XX.so in
   order for CCfits to configure properly.  You can then configure
   CCfits using "--with-cfitsio=$HEADAS".


   You have the option of carrying out the build in a separate directory
   from the source directory or in the same directory as the source.  In
   either case, you need to run the configure script in the directory
   where the build will occur.   For example, if building in the source
   directory with the cfitsio directory in /usr/local/cfitsio/ then the
   configure command should be issued like this:

   > ./configure --with-cfitsio=/usr/local/cfitsio

   If you do the build in a separate directory from the source, you may
   need to issue the configure command something like this:

   > ../CCfits/configure --with-cfitsio=/usr/local/cfitsio

   The configure script will create the Makefile with the path to the
   compiler you choose (or GCC by default), and the path to the CFITSIO
   package.  The configure script has other options, such as the install
   location.  To see these options type

   > ./configure --help


2. Build

   Building the C++ shared library and Java classes will be done
   automatically by running make without arguments like this:

   > gmake


3. Install

   To install, type:

   > make install

   The default install location will be /usr/local/lib for the library
   and /usr/local/include for the header files.  You can change this with
   the --prefix option when you configure, or with something like...

   > make DESTDIR=/usr/local/CCfits install

Compiling CCfits with MS VC++ requires VC++ 7.0 or later.  This is the
compiler that comes with Visual Studio.NET.  Earlier versions of the
compiler has too many defects in the area of instanciating templates.

Take the following steps.

1. Compile the C++ code.  Open the vs.net/CCfits/CCfits.sln file with
Visual Studio.NET.  The includes paths have been set to find the
cfitsio build directory at the same level as the CCfits directory.  If
this is not the case, use Visual Studio.NET to edit the include paths
and extra library paths to where you have cfitsio installed.

Next, just use the build icon or the build menu item.
   
To build the test program, cookbook, use the
vs.net/cookbook.cookbook.sln file
