Ack... Sorry about the last email with unreadable code. My email system does
something strange with some text. Here is the email again with readable code.
Hello.
I have a sample program in 2 formats perl & embperl.
The perl version works as a CGI but the embperl version does not work.
Any suggestions or pointers to solutions would be appreciated
OS: Linux version 2.6.35.6-48.fc14.i686.PAE (...) (gcc version 4.5.1 20100924
(Red Hat 4.5.1-4) (GCC) ) #1 SMP Fri Oct 22 15:27:53 UTC 2010
perl working script:
#!/usr/bin/perl
use warnings;
use strict;
use IPC::Open3;
use Symbol 'gensym';
print "Content-type: text/plain\n\n";
my $cmd = '/bin/ls';
my $pid = open3(*HIS_IN, *HIS_OUT, *HIS_ERR, $cmd);
close(HIS_IN); # give end of file to kid, or feed him
my @outlines = <HIS_OUT>; # read till EOF
my @errlines = <HIS_ERR>; # XXX: block potential if massive
print "STDOUT: ", @outlines, "\n";
print "STDERR: ", @errlines, "\n";
waitpid( $pid, 0 );
my $child_exit_status = $? >> 8;
print "child_exit_status: $child_exit_status\n"
embperl non-working script:
Here is the output I receive.
STDERR: ls: write error: Bad file descriptor
child_exit_status: 2
