Internal Server Error running perl script in browser

Thu Nov 17 16:22:07 GMT 2022

Good day!

I have an issue where I receive "Internal Server Error" when running perl scripts in the browser.  Here's an example script that works OK when running from the Cygwin Terminal:

#!/usr/local/bin/perl
use DBI;
my @ary = DBI->available_drivers();
print @ary;

print "Content-type:text/html\n\n";
print "<html><head><title>My First Script</title></head>\n\n";
print "<body>\n";
print "<p>Hello from <b>mpl.pl</b></p>\n";
print "</body></html>";

Here are the results:

$ perl  mpl.pl
DBMExamplePFileGoferMemODBCProxySpongeContent-type:text/html

<html><head><title>My First Script</title></head>

<body>
<p>Hello from <b>mpl.pl</b></p>
</body></html>

/var/log/httpd/error_log shows:

I have reinstalled DBI, but the symptoms remain.

Enclosed is the output from cygcheck -s -v -r -h > cygcheck_output.txt and httpd.conf, if they help.

Where would you look next?

Thanks!!
