32512 error code in Perl when trying to run shell command

hi

when I execute the command from the shell command line - it works and no error code.
if I do the exact same command from a perl file - it fails with code 32512.
the file is created from the same perl script that runs the command that fails. file permission is 0664.

Code:

#! /usr/local/pkg/perl-5.8.8/bin/perl

print "Content-type: text/html\n\n";

my $commandStr="babel -icif '/mypath/butadiene.cif' -opdb '/mypath/butadiene.cif'";

my $cmdResults=`$commandStr` or print "error code: $?, error string: $!";

result:

error code: 32512, error string:

what could error code 32512 mean in this case? why is it working from the command line and not from the perl script?

Could be because the "babel" command isn't in your path when you run the script. Did you try to specify the entire fully-qualified path to babel? And did you notice that both your input and output files are the same??

In the name of the Flying Spaghetti Monster,

I just tried that with a nonexistent "babel", and got -1, not 32512. 32512 in hex is 7F00. According to the man page for waitpid(), this indicates a return code of 127 from the program. You should find out why babel is returning with an exit code of 127.
