step1下载：

ftp://ftp.gnu.org/gnu/cgicc/

step2:

tar xzf cgicc-X.X.X.tar.gz(用最新版本)

cd cgicc-X.X.X

./configure --prefix=/usr

/var/www/html/testcgi.html:

#include <iostream>
#include <vector>
#include <string>

#include "cgicc/CgiDefs.h"
#include "cgicc/Cgicc.h"
#include "cgicc/HTTPHTMLHeader.h"
#include "cgicc/HTMLClasses.h"

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

using namespace std;
using namespace cgicc;     // Or reference as cgicc::Cgicc formData; below in object instantiation.

int main(int argc, char **argv)
{
try {
Cgicc formData;

// Send HTTP header: Content-type: text/html
cout << HTTPHTMLHeader() << endl;

// Print: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN" "http://www.w3.org/TR/REC-html40/strict.dtd">
cout << HTMLDoctype(HTMLDoctype::eStrict) << endl;

// Print: <html lang="en" dir="LTR">
cout << html().set("lang", "EN").set("dir", "LTR") << endl;

// Set up the HTML document
cout << html() << head() << title("Cgicc example") << head() << endl;
cout << body().set("bgcolor","#cccccc").set("text","#000000").set("link","#0000ff").set("vlink","#000080") << endl;

cout << h1("This is a demonstration of the GNU CgiCC library") << endl;

form_iterator fvalue1 = formData.getElement("value1");
if( !fvalue1->isEmpty() && fvalue1 != (*formData).end()) {
cout << "Value1: " << **fvalue1 << endl;
}
else
cout << "No text entered for value1" << endl;

cout << p();

form_iterator fvalue2 = formData.getElement("value2");
if( !fvalue2->isEmpty() && fvalue2 != (*formData).end()) {
// Note this is just a different way to access the string class.
// See the YoLinux GNU string class tutorial.
cout << "Value2: " << (**fvalue2).c_str() << endl;
}

cout << p();

form_iterator fvalue3 = formData.getElement("value3");
if( !fvalue3->isEmpty() && fvalue3 != (*formData).end()) {
cout << "Value3: " << **fvalue3 << endl;
}

cout << p();

form_iterator fvalue4 = formData.getElement("value4");
if( !fvalue4->isEmpty() && fvalue4 != (*formData).end()) {
cout << "Value4: " << **fvalue4 << endl;
}

// Close the HTML document
cout << body() << html();
}
catch(exception& e) {
// handle any errors here.
cout << "ERROR!!" << endl;
}
return 0;   // To avoid Apache errors.
}

备注：

我虚拟机环境需要开通防火墙：

iptables -I INPUT 4 -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT

The following paths are for a Red Hat 7.x installation.

Place web page in: /var/www/html/testcgi.html

Place cgi in: /var/www/cgi-bin/testcgi

Start Apache: service httpd start

Test: http://localhost/testcgi.html
