Description of issue

I am running homebrew with html and cgi files that I have imported from a Lubuntu setup where they work fine. I have an initial html file that when submitted calls a cgi file that is also a perl file.... here are the first few lines:

#!/usr/local/Cellar/perl -w

#------------------------------

interactive.pl

#------------------------------

print "Content-Type: text/html \n\n";

use File::Copy;
use warnings;
no warnings ('uninitialized', 'substr');
use strict;
use Data::Dumper;
use File::Find;
use CGI;
use CGI qw(:cgi-lib :standard);
use CGI::Carp qw(fatalsToBrowser)

I am not an experienced homebrew user but I think I understand some of the fundamentals. When this cgi file gets called it just displays the raw code, not in html format. I believe I had similar issues in Lubuntu but was able to fix the problems by adding lines to enable cgi in the httpd.conf file and use sudo a2enmode cgid. The a2enmode command is not avaialble now in homebrew. Disclaimer - I have not revisted this code in years and at the time it was not a logical path to success to get the code working in Lubuntu... it was a bit wacamole. However I'm nothing but persistent and all I need to start is to know how I need to enable the cgi and perl aspects of homebrew... I have done brew install perl and changed lines in httpd.conf to try to get this to work .... I have done brew link perl... I have changed the bash line at the beginning of the cgi file (#!/usr/local/Cellar/perl -w) over and over.... I am at a loss. I have loaded and unloaded modules in httpd.conf - nothing seems to work. If anyone could give me some pointers I'd appreciate it..... As a 72 year old wondering why I am doing this sometimes... so cut me some slack... I think if I can get this cgi perl problem fixed it will solve all the issues.

#!/usr/local/Cellar/perl -w

That path points to a directory, not a perl binary. Since you have Homebrew perl installed, this should also certainly be:

#!/usr/local/bin/perl -w

Thanks for the reply, but I had tried that earlier with no luck and I again retried it but no luck.... maybe I have made changes to httpd.conf to compensate and they could have screwed things up. i will go back and recheck that. Anymore suggestions would be appreciated

I ran the file from the command line at got the following: ---------
Can't locate CGI.pm in @inc (you may need to install the CGI module) (@inc entries checked: /usr/local/opt/perl/lib/perl5/site_perl/5.40/darwin-thread-multi-2level /usr/local/opt/perl/lib/perl5/site_perl/5.40 /usr/local/opt/perl/lib/perl5/5.40/darwin-thread-multi-2level /usr/local/opt/perl/lib/perl5/5.40 /usr/local/lib/perl5/site_perl/5.40/darwin-thread-multi-2level /usr/local/lib/perl5/site_perl/5.40) at ./interactive.cgi line 17.
BEGIN failed--compilation aborted at ./interactive.cgi line 17.------------
Line 17 is simply use:CGI

Looks like you don't have the CGI Perl module installed. The paths listed in the error message also indicate that you didn't do the steps listed in the Caveats section of brew info perl. You should probably do those first, but since you've asked to be cut some slack, I'll note that you'll need to do two things with the last command in the caveats (i.e. eval ...):

1. Add that command to your login shell's startup file (~/.profile if bash, ~/.zshrc if zsh) to ensure future shell sessions are set up to use local::lib.
2. Run that same command manually, to ensure your current shell session is set up to use local::lib.

Once all that is done, then cpan install CGI should install the necessary module with a TON of output but no errors. You can confirm that by running perl -e 'use CGI'; it should print nothing if all is well.

Wow. Thanks .. I’m not totally done but I feel like almost there. I noticed those caveats but I didn’t pay too much attention to them. Then they were gone. What a huge install that was of cpan perl. And I got no errors. I would never have had a clue that was how to install Perl. I thought the brew install was the solution. I think I have some issues still with the zshrc file. I have 2 lines in that file. The one you mentioned and another. I can’t seem to figure out the minimum basic config of that file. I get so many suggestions in google but not just a basic homebrew config. Thanks again.

Finally Success... --- your help was very much appreciated. I kept running into the same issue BUT I new CGI was working (through your advice). So I concentrated on the httpd.conf file and finally had success. Unfortunately I don't know if I can pin it down to one thing in the conf file but I believe it was the two
lines. Anyway I can now breathe a little easier... Thanks
