This directory contains the code (source, makefiles, precompiled libraries)
accompanying the talk at the "2015 International Rexx Symposium" in Vienna
(cf. http://rexxla.org/events/2015/schedule.html) entitled "How to Develop a
Native Library in C++ for ooRexx in a Nutshell":

    - the source files for the three nutshell libraries, the Rexx
      programs using them and the appropriate Makefiles to create the
      libraries on Windows, MacOSX and Linux

    - to create the libraries yourself you need the MS compiler on Windows,
      the GNU g++ compiler for Linux and the Clang compiler for MacOSX;
      see the first line in the appropriate Makefiles how to invoke the
      respective make command

    - running the examples with the pre-built libraries:

        - determine first the bitness of your installed ooRexx by
          issuing a "rexx -v" and studying its output

        - copy the appropriate link libraries from the 32- or 64-bit
          subdirectories into the directory containing the Rexx test
          programs (file type ".rex")

        - Windows: you are set to run the Rexx test programs
        - Linux:   enter "export LD_LIBRARY_PATH=.:$LD_LIBRARY_PATH"
                   before running the Rexx test programs
        - MacOSX:  enter "export DYLIB_LIBRARY_PATH=.:$DYLIB_LIBRARY_PATH"
                   before running the Rexx test programs

If you have any questions, please use the RexxLA-mailing list (cf.
<http://www.RexxLA.org>) or the ooRexx developer list on Sourceforge (cf.
<http://sourceforge.net/projects/oorexx/>).
