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

3.5 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
