Most of the utility programs in the frame locker are failing to run on
any platform because of this part of
/mit/frame_v4.0/arch/share/bin/maker:
(cfyi: skip to the end for a workaround for users if you don't care
about the details.)
sub handle_resources
{
local ($default_printer, $host, $printer_set);
if (defined ($ENV{"DISPLAY"})) {
# Monochrome displays
if (grep (/-DPLANES=1/, `xrdb -symbols`)) {
push (@arglist, "-xrm", "Maker.textStippleFilled: False");
}
# Maker.printerName resource for print dialog box
$printer_set = grep (/Maker[\.\*]printerName/, `xrdb -q`) ||
grep (/printerName/, @arglist);
if ( $printer_set == 0 ) {
$default_printer = $ENV{'PRINTER'};
if ( length ($default_printer) == 0 ){
chop ($host = `hostname`);
open (CLUSTER, "hesinfo $host cluster |");
while (<CLUSTER>) {
next unless /lpr/;
($default_printer = $_) =~ s/(^lpr )([a-z]*)/$2/;
chop ($default_printer);
}
close CLUSTER;
# Give them something so that print to file works.
if (length ($default_printer) == 0) {
$default_printer = "python";
}
} #
push (@arglist, "-xrm", "Maker.printerName: $default_printer");
}
}
}
This routine is called for *every* program. This routine's purpose is
to cause certain host-specific configuration to be passed via -xrm
arguments to programs which use X. Unfortunately, -xrm is an invalid
argument for programs which don't use X, most notably the conversion
programs.
Workaround:
I'm not sure what the right solution is, but this isn't it. Until the
right solution is found, a workaround is to run
(unsetenv DISPLAY ; progname arg1 arg2 ...)
This fools the script into believing that an X display isn't present,
so X resources will be meaningless.
