使用php写后端程序的例子很多，用c/c++的比较少。
本文采用nginx,spawn,fastcgi++来构建一个基于cgi的web程序。
由于fastcgi++依赖于boost库，我们先来装boost库
Linux下编译boost
1.编译前的准备工作
|
1
|
sudo yum install bzip2 bzip2–devel bzip2–libs python–devel –y
|
2.下载安装包并解压
|
1
2
|
#wget http://netcologne.dl.sourceforge.net/project/boost/boost/1.61.0/boost_1_61_0.zip
unzip boost_1_61_0.zip
|
编译安装
|
1
2
3
|
#cd boost_1_61_0
./bootstrap.sh
sudo ./b2 install
|
测试boost库是否可以使用，boost编译完成后运行程序报错，

最开始以为是bzip2没装上，折腾了许久也没搞定，最后我发现boost的官方文档写着gcc4.4.7，而我本地的编译器是4.4.6，之后我把gcc升级到4.8重新编译通过。
redhat6.3升级gcc4.8.0编译安装方法：
1.下载源码并解压
|
1
2
|
wget http://ftp.gnu.org/gnu/gcc/gcc-4.8.0/gcc-4.8.0.tar.bz2
tar –jxvf gcc–4.8.0.tar.bz2
|
2.下载编译所需的依赖项
|
1
2
3
|
cd gcc–4.8.0
./contrib/download_prerequisites
cd ..
|
3.建立编译输出目录
|
1
|
mkdir gcc–build–4.8.0
|
4.进入此目录，执行以下命令，生成makefile文件
|
1
2
|
cd gcc–build–4.8.0
../gcc–4.8.0/configure —enable–checking=release —enable–languages=c,c++ —disable–multilib
|
5.执行以下命令进行编译，编译时间比较长
|
1
|
make –j4
|
6.安装
|
1
|
sudo make install
|
安装完成后查看版本

重新执行boost的编译，编写一个例子测试是否成功

我的报错如下，因为升级了gcc4.8,没有升级libstdc++.so.6导致。
