Hello, im very new to perl, modperl and apache but im doing a university
project to use modperl to provide a connection to a localised Gnu Octave
installation.
I have come against a problem when trying to run this simple test program:-
package Apache::OctavePrototype;
use FileHandle;
use IPC::Open2;
use Apache::Const -compile => ':common';
use Apache::Request;
use Apache::Process;
use Apache::Upload;
sub handler {
my $r = Apache::Request->new(shift);
my $octave_cmd = $r->param('octave_cmd') || 'No Command';
my $output_text;
$r->content_type('text/html');
my $pid = open2( \*ReaderFH, \*WriterFH, "sh.exe -e /bin/start_octave.sh");
my($read);
for (1..11)
{
$read = <ReaderFH>;
$output_text = $output_text.$read;
}
$r->print($output_text);
return OK;
}
1;
__END__
I get an error generated in the apache error log file:-
C:/Perl/site/lib/Apache2/Apache/OctavePrototype.pm line 19\n
[Wed Feb 09 13:25:34 2005] [error] [client 127.0.0.1] open2: Can't close: No
such file or directory at
Traced to the lines in the IPC:Open3 module :-
foreach $fd (@$fds) {
$fd->{handle}->fdopen($fd->{tmp_copy}, $fd->{mode});
$fd->{tmp_copy}->close or croak "Can't close: $!";
}
Im using a perl/apache binary - Perl-5.8-win32-bin.exe downloaded form
http://httpd.apache.org/ and windows xp.
Anyone with any help or ideas please let me know
thanks in advance
