Troubleshooting

I am running Solaris (SunOS 5.x), and the Sun4 version of XWPL doesn't work.

    Solaris is not always compatible with SunOS 4.1.x in binary compatibility mode. There is a Solaris 2.3 version of XWPL which you should use instead.

On my NeXT computer, XWPL aborts after a message "Error: Can't open display:"

   XWPL is an X Window System application, not a NeXTstep one. You need a NeXT X server to run it. Due to poor NeXTstep 3.1 Posix conformance, the NeXT port is on hold indefinitely. Otherwise, you could use the WPLab program, which is NeXTstep-based. It is available from wuarchive.wustl.edu in the directory /doc/techreports/wustl.edu/math/software.

The colors in the phase box are a day-glo nightmare.

  XWPL tries to be a ``good citizen'' by not agressively grabbing colors from the colormap. If you have a colormap hog running (graphics display or fancy background screens, for instance), they will interfere with it. Quit your color-intensive applications and/or restart your X server.

On my Silicon Graphics workstation, the phase diagram is wishy-washy or even invisible, and the colors are hard to see.

   This problem is due to the special graphics hardware and colormap situation on 24-bit SGI workstations. You must use the palette, showmap, interp commands to adjust your colormap.

I have added a file to the directory from which XWPL is reading, but it doesn't appear.

  The XWPL file browser does not poll to see if the contents of the directory have been updated. To do so, simply double-click on the ``.'' directory to re-read the current directory.

XWPL crashes with a BadAlloc error.

   There is a bug in the HP X server which incorrectly allocates backing-store. The HP version of XWPL has a workaround.
