1. Issue:

I have installed Apache (see the referenced phpinfo output for more details) and I am trying to demonstrate C++ scripting with a "Hello Word" example. This is mostly a setup issue.

Once 64-bit Apache is installed, what else needs to be done to get C++ scripting to work? Is that done in the php framework?

-A small program for instance could be created as a cgi script that would just run the compiler and run the output generated as an interpreter of sorts.

-But with PHP, it is possible to just load the .dll; why not also with C++?

I like C++ because of the way that it is possible to organize the code;
-I like the hierarchical structure better; it seems more flexible
-Also, it is easier to translate between paper documents and C++ code

2. Probing
-I tried to find references to the issue; I remember reading material before that seemed to suggest that it might be possible directly.
-From GCI, it seems that it is possible to compile the programs as modules that can load into Apache directly

3. Analysis
-I am not finding the direct approach for a C++ interpreter that would work like PHP; however the indirect approach of compile and run might be possible
-The workaround would be to build the CGI interface in C++ and compile it and then run it.

4. Isolation
-I am trying to see if Cygwin would work with its language package following:

Cygwin - Part Two - Installing GCC[1]

and also following

Cygwin - Part Three - Testing the GCC C++ Compiler[2]

and most importantly "Introduction to C++ CGI":

Introduction to C++ CGI | Guy Rutenberg[4]

See the references for more detail (and additional perhaps related information).

4. Resolution

No resolution yet; Is there a C++ interpreter available? Or does the software need to be written in C++ again (I guess to use the Cygwin compiler from windows to take a given code, save it, and then compile it and run it, or the equivalent under Windows or other operating systems.)

Update #1:

I found a sample file printenv.pl and I modified that slightly (changing the header), after checking the error logs for Apache. The new code is:

PERL

#!C:/Perl64/bin/perl.exe
# To permit this cgi, replace # on the first line above with the
# appropriate #!/path/to/perl shebang, and on Unix / Linux also
# set this script executable with chmod 755.
#
# ***** !!! WARNING !!! *****
# This script echoes the server environment variables and therefore
# leaks information - so NEVER use it in a live server environment!
# It is provided only for testing purpose.
# Also note that it is subject to cross site scripting attacks on
# MS IE and any other browser which fails to honor RFC2616.
##
## printenv -- demo CGI program which just prints its environment
##
use strict;
use warnings;
print "Content-type: text/plain; charset=iso-8859-1\n\n";
foreach my $var (sort(keys(%ENV))) {
my $val = $ENV{$var};
$val =~ s|\n|\\n|g;
$val =~ s|"|\\"|g;
print "${var}=\"${val}\"\n";
}

Ouch! Someone/thing have complicated the issue for you needlessly. It can be as simple as outputting to stdout for output (using printf/cout etc). If you're running XAMPP under windows, you build the program, drop the .exe into the cgi-bin folder of the appache installation and hit it with the browser.

Here's a minimal example:
cgiTest.c

#include <stdio.h>
#include <stdlib.h>

int main()
{
    printf("Content-Type:text;charset=iso-8859-1\r\n\r\n");
    printf("Hello webWorld from .C program");
    return(0);
}

I just hit it with the url "localhost/cgi-bin/cgiTest.exe"

The topic is of course, far broader and there are many caveats and gotchas that I wont cover. I do recall there being a library called fastcgi or something like that, which will allow you to handle GET/POST requests etc. There's naturally going to be something that allows you to send back a gzipped output etc, etc.

After playing with it for a few days a couple of years back, I was able to take a photo using the web-cam and send the image to the browser. It's relatively straight forward - dealing with the camera was far harder than any of the stuff that made it web-friendly, or "cgi-able"

StephenJElliott 9-Feb-16 3:52am

Thank you for the update.. I ended up not using XAMPP under windows, just Apache, PHP and MySQL; finally it seems to work. The important thing is to have a version with the .exe extension to see if the .exe actually runs! Of course in the cgi-bin directory for the Apache web server, the .exe extension is changed to .cgi for the web server to be able to present the output. I had wanted to use C++ as a scripting language so that I could program certain segments later, but in the meanwhile php can be used directly within WordPress for instance, which relies on a database (so the coding becomes a document issue instead of a presentation issue with the document being in the database).

Richard MacCutchan 3-Feb-16 11:11am

Since C++ is not a scripting language, you need to capture the complete source, and then compile and link it into an executable module.

StephenJElliott 4-Feb-16 3:56am

I am able to get perl to execute (more details in the main text). So the question is why is the main code not executing. I wonder if I write a perl script that just has the first line with the index to the actual code that I want to run, if that would work.

Richard MacCutchan 4-Feb-16 4:03am

Sorry, but I am not sure I understand what problem you are trying to solve. And having just re-read your main question, am even more confused.

Richard MacCutchan 4-Feb-16 7:28am

Seriuosly? You cannot expect people to trawl through all that code to try and make sense of what is happening.

StephenJElliott 7-Feb-16 4:25am

Example C code works fine. The question, is there a C++ interpreter that is directly callable as a cgi script or do I need to write a short handler to save the file and then call the compiler each time to compile it. This would be for dynamic coding. Right now I am leaning toward using an existing compiler - cygwin because it just happened to install nicely, and starting out by compiling everything by hand. But there is no reason why this could not be virtual in the future I suppose to make planning easier.
