Systems Tested and Known Bugs

The development team has run PADE on the following operating systems and computers to date:

• NeXT OS 3.1/NeXT Motorola 68040
• NEXTSTEP 3.2/Intel Pentium
• AIX 3.2.5/IBM RS/6000
• IRIX 5.2 and 5.3/Silicon Graphics
• SunOS 4.1.3/SUN SparcStation 20
• Linux 1.0.9 and 1.2/Intel 80486
• UNICOS 8.0.3.2/Cray Y-MP
• ConvexOS 11.0.149/Convex 3820
• HP-UX 9.05/HP 735

It should be kept in mind that the functionality of PADE depends upon that of the other programs mentioned in Chapter 1, and the recommended first step in troubleshooting is to verify that they are properly implemented on the development host.

The following problems have been encountered during testing:

• On some hosts, PVMmake has difficulty finding the wc program. PVMmake uses this program (for packing purposes) to count the number of lines in a file that is to be transferred. If this error occurs, PVMmake will so indicate and exit. In this case, the user should create a symlink in the PVM binary directory to the actual location of the wc program.

• On the NIST Cray Y-MP, PVMmake requires the definition of the macro O_RDONLY. If PVMmake fails to compile, edit the file jlib.h in the caml_utils directory to remove the comment around line 9.

• On rare occations, PADE has produced the error message

  invalid command name "FindCmd"
  

  before creating the main PADE window. This indicates that either the PADE_ROOT environment variable points to the wrong directory, or there is a problem with the tclIndex file. If PADE_ROOT is set correctly, then regenerate the tclIndex file by:

  host-prompt> tclsh
  tcl-prompt> auto_mkindex . *.tcl
  tcl-prompt> exit
  host-prompt>
