Hello Wise Monks...
I have the following code running as CGI. It starts to run and returns an empty PDF file to the browser and writes an error message to the error_log.
Do you have any wisdom on how to solve this?
linux: 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 2

wkhtmltopdf: wkhtmltopdf 0.10.0 rc2
perl: This is perl 5, version 12, subversion 2 (v5.12.2) built for i38

Thank You in Advance. ~Donavon
perl CODE:
#!/usr/bin/perl
#### takes string containing HTML and outputs PDF to browser to downlo
+ad
#### (otherwise would output to STDOUT)
print "Content-Disposition: attachment; filename='testPDF.pdf'\n";
print "Content-type: application/octet-stream\n\n";
my $htmlToPrint = "<html>a bunch of html</html>";
### open a filehandle and pipe it to wkhtmltopdf
### *the arguments "- -" tell wkhtmltopdf to get
### input from STDIN and send output to STDOUT*
open(my $makePDF, "|-", "/usr/local/bin/wkhtmltopdf", "-", "-") || die
+("$!");
print $makePDF $htmlToPrint; ## sends my HTML to wkhtmltopdf which st
+reams immediately to STDOUT
error_log message:
