Hi

I have been trying to run simple helloworld.cgi in Xampp cgi-bin but unsuccessfully (helloworld.pl also does not work).

http://localhost:8080/cgi-bin/helloworld.cgi
The error message is:
Server error!
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there was an error in a CGI script.

If you think this is a server error, please contact the webmaster.

The error log:

The helloworld.cgi:
#!C:\xampp\perl\bin\perl.exe

# Tell perl to send a html header.
# So your browser gets the output
# rather then <stdout>(command line
# on the server.)
print "Content-type: text/html\n\n";

# print your basic html tags.
# and the content of them.
print "<html><head><title>Hello World!! </title></head>\n";
print "<body><h1>Hello world</h1></body></html>\n";

What am I doing wrong & can anyone help me fix this please?

Further to my first post I am still having problems with this and am posting another example when I tried to run a different perl script (first.pl) from xampp cgi-bin folder.
This is the resulting error message:

Server error!
The server encountered an internal error and was unable to complete your request.

Error message:
couldn't create child process: 720003: first.pl

If you think this is a server error, please contact the webmaster.

I have been doing internet searches to find the cause of these problems but haven't found the solution yet.
Can someone please reply with help so I can run perl & cgi scripts from Xampp cgi-bin?
I look forward to helpful replies, thanks

Hi again
I solved the issue with first.pl by changing first.pl shebang line to point to Xampp/perrl

ie:
Change this first.pl
[http://httpd.apache.org/docs/2.0/howto/cgi.html]
#!/usr/bin/perl
print "Content-type: text/html\n\n";
print "Hello, World.";

to this first.pl
#!/xampp/perl/bin/perl -w
print "Content-type: text/html\n\n";
print "Hello, World.";

I had tried a similar (but not exactly the same) shebang line for my first issue to point to xampp/perl.
I will try this shebang line & see if all works to solve my first problem & my issue of using .pl & .cgi in Xampp cgi-bin.
(I used this shebang line from this link/ post on apachefriends forum:http://community.apachefriends.org/f/viewtopic.php?p=68577&sid=4293c830a984784bbc9d26123bd33c35)

I hope this post helps anyone else struggling with this!

As my last post stated my new shebang line in first.pl worked so I thought this would work for helloworld.pl
and I changed this to the same shebang line but this does not run in local host browser!

Here is helloworld.pl

#!/xampp/perl/bin/perl -w

# Tell perl to send a html header.
# So your browser gets the output
# rather then <stdout>(command line
# on the server.)
print "Content-type: text/html\n\n";

# print your basic html tags.
# and the content of them.
print "<html><head><title>Hello World!! </title></head>\n";
print "<body><h1>Hello world</h1></body></html>\n";

and this brings up this error message again:
Server error!
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there was an error in a CGI script.

If you think this is a server error, please contact the webmaster.

Very strange!

So my xampp cgi-bin issues are not yet fully fixed! I am still grateful for any helpful replies to help me understand & fix this....
Thanks

Oh dear! Another post soon after my last one!
I changed helloworld.pl to helloworld1.pl by removing all the 'hashed' comments
ie:
#!/xampp/perl/bin/perl -w

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

print "<html><head><title>Hello World!! </title></head>\n";
print "<body><h1>Hello world</h1></body></html>\n";

and guess what? This displays correctly in localhost browser now!
What was the matter with the comments in the original helloworld.pl script?

Anyway I am slowly making progress and hope to learn about perl and cgi using Xampp localhost. This could be an interesting learning curve!
