SPICE Toolkit from NAIF. More computer engineering friendly

Basic project structure:

                  package
                     |
                     |
   +------+------+------+------+------+
   |      |      |      |      |      | 
 data    doc    etc    exe    lib    src
                                      |
                                      |
                     +----------+----------+------- ... ------+
                     |          |          |                  |
                 product_1  product_2  product_3    ...   product_n

Basic compilation strategy:

1. Compile all of the .c files in the current product directory

2. If there are no .pgm files in the current directory this is assumed to be a library source directory. The name of the library is the same as the name of the product (directory name). The library is placed in the "lib" directory in the tree above.

3. If any *.pgm files exist in the current directory, compile them and the *.c files. Compile the main program(s) and link its object with the previously compiled *.c files, and libraries ../../lib/cspice.a and ../../lib/csupport.a. The output executables have an empty extension. The executables are placed in the "exe" directory in the tree above.

The environment variable TKCOMPILEOPTIONS containing compile options is optionally set. If it is set prior to executing this script, those options are used. It it is not set, it is set within this script as a local variable.

All these actions are now handled by the Makefile files coded. 2 action targets are allowed using those Makefiles:

• all (default action): Compiles all within de current directory
• clean: Deletes all precompiled objects, libraries and binaries

Current compilation procedure

Execute "make" on the project root directory and you are done (as almost any Makefile based project).

It you need to delete those files result of a previous project generation, just execute "make clean" on the directory you want to clean (includes sub-directories).

TODO (Upcoming features and fixes)

• Support for DESTDIR on Makefiles
• Target support for system installation (make install)
