Use CGI::CARP qw(fatalsToBrowser) not working

Hi all,
When I include this line in the script, the errors don't appear within
the browser window. I am still having to dig through the error_log to
find out what happened, or execute perl test.cgi from a terminal window.

The following is displayed in the browser if any error occurs within the
script:

SERVER ERROR
The server encountered an error ………….
Error message:
Premature end of script headers: test.cgi

OS: recently installed RH9 (SHRIKE)

Could this be an Apache httpd.conf setup error?

Perl is case sensitive.

use CGI::Carp qw(fatalsToBrowser);

Re: Use CGI::CARP qw(fatalsToBrowser) not working

Hi again all,
I posted the question as: Use CGI::CARP qw(fatalsToBrowser) not working
When in fact the code I have within the script is:
use CGI::Carp qw(fatalsToBrowser)

This is not functioning correctly. The outputs don't go to the browser
window.

Anybody with any hints?

Joe

Thanks - Gunnar Hjalmarsson for pointing out the mistake in the subject
line

Is CGI::Carp correctly installed? Try this script:

#!/usr/bin/perl
use CGI::Carp qw(fatalsToBrowser);
print "Content-type: text/plain\n\n";
print CGI::Carp->VERSION, "\n";

Are you running under mod_perl?

Well, the obvious question is are you sending the correct headers? Sounds
like your script is executing fine, but your sending an improper header to
the browser, and malformed http headers are not going to be caught by the
perl interpreter.

Not that obvious, since CGI::Carp prints a content-type header. The OP
also gave the impression that the script normally runs without errors
("if any error occurs").

Ahh, I didn't read down through the tofu. All I saw was his reply that it's
not working and that he's getting a header error. I'm still suspect as to
what these errors are that he believes should be caught by CGI::Carp.

The output of the above script was 1.24

Can you show us a small script with an error that is not captured by
CGI::Carp as you would have expected?

IIRC, version 1.24 is buggy. It may be worth to try the latest version.
