cgicc使用

CgiCc 使用

一、下载

下载地址：

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

二、配置、编译、安装

下载完成后解压：shell tar xzf cgicc-X.X.X.tar.gz
进入解压的目录： ```shell cd cgicc-X.X.X/
配置

./configure --prefix=/opt

--prefix 参数指定安装目录，默认安装目录为/usr

编译

make

安装

make install

三、例程

3.1 如果在64bit平台编译32位库：

CXXFLAGS="-m32" CFLAGS="-m32" LDFLAGS="-m32"

3.2 如果安装目录为/opt：

编译时指定包含路径：shell -I/opt/include
编译时指定引用路径：shell -L/opt/lib

3.3 HTML Demo

testcgi.html

<html>
<head><title>Test CGIcc form</title></head>
<body bgcolor="#cccccc" text="#000000">
<h2>Test CGIcc form</h2>
<p>
<form method="post" action="/cgi-bin/testcgi.cgi">
Value 1 :
<input type="text" name="value1">
<p>
Value 2 :
<select name="value2">
   <option value="option1">Option 1
   <option value="option2">Option 2
   <option value="option3">Option 3
</select>
<P>
Value 3 :
<input type="radio" name="value3" value="button1" checked="checked">Button1
<input type="radio" name="value3" value="button2">Button2

<input type="hidden" name="value4" value="data4">
<p>
<input type="submit" value="Submit">

3.5 编译c++ CGI demo

使用静态库编译
如果安装在/opt/：g++ -o testcgi.cgi -I/opt/include testcgi.cpp /opt/lib/libcgicc.a
如果安装在/usr/：g++ -o testcgi.cgi testcgi.cpp /usr/lib/libcgicc.a
使用动态库编译
如果安装在/opt/：g++ -o testcgi.cgi -I/opt/include testcgi.cpp -L/opt/lib -lcgicc
如果安装在/usr/：g++ -o testcgi.cgi testcgi.cpp -lcgicc

3.6 运行

将testcgi.html 拷贝到 /var/www/html/
将 testcgi.cgi 拷贝到 /var/www/cgi-bin/
本机测试 : http://127.0.0.1/testcgi.html
