//说明
error: C++ preprocessor "/lib/cpp" fails sanity check 问题的解决
 问题的根源是缺少必要的C++库。如果是CentOS系统,运行,如下命令解决:
 yum install glibc-headers
 yum install gcc-c++

再执行

[root@VM_0_5_centos swoole]# ./configure --with-php-config=/home/work/study/soft/php/bin/php-config
[root@VM_0_5_centos swoole]# make
[root@VM_0_5_centos swoole]# make install

/home/work/study/soft/php/lib

在php.ini文件中添加:extension=swoole.so

查看是否添加成功:php -m

[root@VM_0_5_centos server]# php echo.php 
^C
[root@VM_0_5_centos server]# pwd
/home/work/study/softpackage/swoole/examples/server
//新开窗口
