This file is install.win. It contains installation instructions for
cgi.tcl on Win95/NT.
If you do not have Tcl, get it (the README explains how) and install
it. The rest of these instructions assume that you have Tcl
installed.
--------------------
Installation
--------------------
These instructions are based on contributions courtesy of Maan
M. Hamze <mmhamze@pleiades.net> and Martin Meuer
<martin.meuer@frz.de>. Send fixes to me (libes@nist.gov).
If you just want to experiment with cgi.tcl, you can simply source it
into your Tcl files by saying "source cgi.tcl".
Once you're done playing, go ahead and install it. To install it:
1) Open wish8.0 and run the following:
pkg_mkIndex c:\\tcl\\lib\\tcl8.0 cgi.tcl
(assuming that you have Tcl libraries in the above directory). This
This will create pkgIndex.tcl which will make it possible to use
"package require cgi" in scripts.
2) The only files actually necessary for production use are
pkgIndex.tcl and cgi.tcl. Make sure those files and their directory
have execute permission for the web server scripts.
3) You may want to edit some things in cgi.tcl at this time.
3a) The default extension of the files that work with cgi.tcl is .cgi.
In case that extension is already being used by another program for
your cgi programs, you may want to change that extension into
something else, say, .cgt. To do that, search cgi.tcl for the string
.cgi and replace with .cgt or whatever you prefer.
3b) Upon errors in production code, cgi.tcl sends mail to an
administrator. This can be set on a per-script basis but it defaults
to "root". You'll probably want to change this for your site. To do
that, search cgi.tcl for cgi_admin_mail_addr "root" and change the
argument to whatever you prefer.
3c) The cgi_mail_end procedure attempts to do mail delivery using SMTP
(the de facto Internet mail protocol). However, this mechanism is not
robust. For example, if the mail gateway is down, the mail will not
be requeued for later delivery. If you have a robust mailer program
or some other interface, you should switch to using it. The ability
to send mail isn't required for basic use of cgi.tcl, but this ability
is especially useful for in-the-field debugging so I encourage you to
use it.
4) Tcl/Tk 8.0 should have automatically created a file type to run
files with the .tcl extension. Make sure by running:
Explorer...Options....File Types. .tcl files should be associated
with Wish8.0.
5) The web server must now be told about Tcl. The exact details
depend on your particular server. Here are instructions that people
have sent to me for different servers. (Feel free to send more.)
5a) If you are using Personal Web Server for Win 95 or MS IIS ver 3
for Win NT:
Instructions according to Maan M. Hamze <mmhamze@pleiades.net>
Run the Registry Editor.
Go to:
HKEY_LOCAL_MACHINE
System
CurrentControlSet
Services
W3SVC
Parameters
Script Map
Create a new String Value through Edit:
First enter the name of the extension (.cgi or the extension you want to use as
in .cgt). Associate the extension with:
FullPathToTclExecutable\tclsh80.exe %s
5b) If you are using Netscape Enterprise Server:
Instructions according to Martin Meuer <martin.meuer@frz.de>.
5b1) Create an association from NT-Explorer (View-Options-Filetypes) for
the extension .cgt to tell NT to open .cgt with "/fullpath/tclsh80.exe
%1"
5b2) From the Server Manager of the Enterprise Server create o new MIME
type for .cnt with type "magnus-internal/shellcgi"
(Alternatively one can create a special shellCGI-Directory instead,
but I rather like to place my scripts anywhere.)
6) Kill and restart your web server.
You're done! Now you can use cgi.tcl.
