-
- This directory contains examples which demonstrate the usage
- of the CALL_EXTERNAL function under Unix.
-
- To run the examples routines, first the shared object libraries must
- be built. To build the shared object libraries, issue the following
- command:
- % make
-
- Note: To make all the example shared object libraries, a
- C and a Fortran compiler are required.
-
- To run the call_external() examples, start IDL and call
- one of the following IDL procedures at the IDL command prompt:
- IDL> c_only
- IDL> simple_c2f
- IDL> ftn_only
-
- To clean up the directory:
- % make clean
-
- The makefile uses the correct options for the standard compiler
- for each supported system. If you use a different compiler,
- you may need to change the compilation or link flags. Also, each
- of the IDL procedures contains logic to set the name of the
- entry point in the shared library. The name of the entry point
- in the CALL_EXTERNAL call may be incorrect if you use a different
- compiler.
-
- Each System makefile assumes that the location of IDL is
- /usr/local/rsi/idl_5. If this is not the location of your IDL
- installation, edit the makefile for your system. The macro IDL=
- will need to be changed to the location of you IDL distribution.
