./swoole_config.h:22:2: error: #error “GCC 4.8 or later required”

Centos下php7安装swoole 扩展的时候,提示的错误。我记得gcc 版本升级过一次到4.8.5,无语。

root@netpc.com.cn swoole-4.3.5]# gcc -v

老旧共存啊?!

先找下到底有多少gcc

[root@netpc.com.cn ~]# find / -name ‘gcc’
/usr/bin/gcc
/usr/libexec/gcc
/usr/lib/gcc
/usr/local/bin/gcc
/usr/local/libexec/gcc
/usr/local/lib/gcc
/usr/local/src/gcc-4.8.5/gcc-build-4.8.5/gcc
/usr/local/src/gcc-4.8.5/gcc
/usr/local/src/gcc-4.8.5/gcc/testsuite/ada/acats/tests/gc

接着替换下:

mv /usr/bin/gcc /usr/bin/gcc4.1.2
ln -s /usr/local/bin/gcc /usr/bin/gcc

搞定
