There is some documentation on the internet about this. I would recommend
searching the mailing list archive for "CGI" problems.
I had the same problem as you, I tried off and on for ages to get euphoria
working through CGI. I changed everything around so much I recognize in
retrospect I got 99% of this right everytime but also I missed one directive
everytime too. Please realise before you get frustrated with euphoria that it is
*worth* investing time learning the concept of CGI programming in general - it
will help with whatever language you end up using to do CGI.
To do any CGI you have to have a webserver, basically. It's easiest if you use
Apache for this because it's the dominant server and there is more documentation
for this than any other at present (due to its cultural lineage).authoritave
I'm making a presumption you are using Windows here. Install Apache as normal,
using the default options. This should add "Apache" to your "Start Menu"
programs. Under "Apache HTTP Server ......" You will find "Configure Apache
Server", on which click "Edit Apache httpd.conf...."
This is a file you're going to have to get used to. Apache is generally
configured by a text configuration file, rather than tabbed dialog windows like
most programs. It's easier if you just bite the bullet and experiment. I would
save the original file as a backup somewhere, and go nuts with the following (you
can always revert to the saved version - don't delete it!)
First, read the website http://www.cklester.com/euphoria/?page=apache - this is
the most authorative website I have seen on this issue. Don't worry if parts of
it go over your head, just do it all step by step, and experiment ( I cannot
stress enough - back-up the original httpd.conf ).
These are the first things I do when setting up Euphoria for CGI on a new
computer
*) First things first, you need apache to be working - hit your ip address in
your web browser, and it should give you a page that informs you Apache is
working. If it is not working, there's no point even contemplating CGI - you'll
need a webserver. If it doesn't work "out of the box" then you'll need to take
this to an Apache specific group. Apache must work first and foremost
*) Create a shorcut to Apache Error log file on your desktop or whatever folder
is easiest for you. Go to the Start Menu, to Apache, then Review Server Log
Files, then "Review Error Log". Left click on it, move it over your desktop or
whereever is a convenient folder to have the link, and hold down the ALT key
before you let go (this creates a shortcut, rather than moving the menu item).
You'll need it.
*) Through the start menu (you might want to create a shortcut for this too),
edit httpd.conf for the following lines: the easiest way is to copy these and
"search" for them in the text file
Find the line "LoadModule cgi_module modules/mod_cgi.so" - make sure it does not
have the character '#' at the start of the line. It should look like this
LoadModule cgi_module modules/mod_cgi.so
not this
#LoadModule cgi_module modules/mod_cgi.so
Go through the steps as detailed on CK Lesters website
A good way to test whether Euphoria is working or not as a CGI implementation is
to create a file in your web directory which is "Euphoric" (following what the CK
Lester website documents, ends in exw,exu, etcetera)
Hit it. If it says "Internal Server Error" then you are away laughinng. Euphoria
is working with CGI, you just need to move onto the next step which is simple -
the first line of every "euphoria cgi file" should be a "shebang" line - a #
followed by the path to the Euphoria interpreter. for now just put the full
windows path
Secondly, the second line of each file should be this :
puts(1,"content-type:text/html\n\n")
Then put something like this or whatever:
puts(1,"Hello World!")
It can get a lot more complicated than this, but you'd be moving onto the world
of the world wide web, rather than specific Euphoria example problems.
I'm sorry it sounds so complicated, but you'd have to cover half of this to
really even get anywhere with PHP, which is *substantially* more complex and
slower than Euphoria.
On a final note, with Apache every directory is allowed to be defined privelages
- in Linux you can define some of these through the Operating System itself - but
you can also define these in a file also. You can control a whole lot of shit
through the .htaccess file, but you should not need to deal with it certainly not
before you've mastered simple euphoria programs.
