A CGI test program with a misterious error

Hello listers,

This is my first message. I am trying to walk the first steps in web 

development, so I am pleased to enter in Apache's world.

I have two test CGI programs writen in Pascal. The first one writes some 

input using "writeln". The second one uses specific CGI classes. The 

first runs, the second doesn't.

The natural conclusion would be: "Luciano, you are in the wrong list. 

The problem is in your Pascal code, not in Apache". This truth would 

seem logical if the error was  produced in other machines. Yes, the 

first example runs in other machines; the second doesn't run only in mine.

Permissions? the problem can be lack of permissions in CGI folder. No, 

for each file in /usr/lib/cgi-bin, I did:

sudo chmod +x file

Apache is configured because the first example runs. All the files in 

cgi-bin has enough permission to be executed. There's no error in Pascal 

code because both examples run in other machine.

In browser, I have always the error 500: Internal  exception server. In 

Apache's log, I have:

[Tue Oct 18 15:50:36 2011] [error] (8)Exec format error: exec of 

'/usr/lib/cgi-bin/test3' failed

[Tue Oct 18 15:50:36 2011] [error] [client 127.0.0.1] Premature end of 

script headers: test3

Does someone have any idea what it can be done or witch is the nature of 

the problem?

Luciano
