Installing DirAx

  1. Copy the tar file into an empty directory, for example /usr/local/src/dirax/dirax1.15.tar.Z
  2. cd /usr/local/src/dirax/
  3. Uncompress with uncompress dirax1.15.tar.Z
  4. Untar the file with the command tar -xvf dirax1.15.tar
    (If you have GNU tar, you could skip the uncompress step and use gtar -xvfZ dirax1.15.tar.Z)
  5. Create with your editor a file /usr/local/bin/dirax (or somewhere else in your searchpath). This file should contain two lines:
     #!/bin/sh
     exec /usr/local/src/dirax/dirax "$@"
    
  6. Make this file executable: chmod ugo+x /usr/local/bin/dirax
  7. The help command will activate a webbrowser (firefox, mozilla, netscape). You may define another browser by adding a BROWSER alias in the file /usr/local/src/dirax/dirax.init (for example \alias browser mybrowser) or define an environment variable BROWSER.
  8. You should now be able to use dirax.
  9. You may run the command dirax < ex_solutions.inp > ex.out. and compare the results with the file ex_solutions.out in the distribution.

Notes

  1. DEC-Alpha: Some versions of netscape (e.g. version 4.7) cannot be started from within DirAx, but DirAx will display the documentation once netscape is running.
