想打包一个swoole最新版，出现 问题如下：

 cc -I. -I/root/rpmbuild/BUILD/swoole-src-4.2.12 -DPHP_ATOM_INC -I/root/rpmbuild/BUILD/swoole-src-4.2.12/include -I/root/rpmbuild/BUILD/swoole-src-4.2.12/main -I/root/rpmbuild/BUILD/swoole-src-4.2.12 -I/usr/local/php/include/php -I/usr/local/php/include/php/main -I/usr/local/php/include/php/TSRM -I/usr/local/php/include/php/Zend -I/usr/local/php/include/php/ext -I/usr/local/php/include/php/ext/date/lib -I/root/rpmbuild/BUILD/swoole-src-4.2.12 -I/root/rpmbuild/BUILD/swoole-src-4.2.12/include -I/root/rpmbuild/BUILD/swoole-src-4.2.12/thirdparty/hiredis -DHAVE_CONFIG_H -Wall -pthread -g -O2 -c /root/rpmbuild/BUILD/swoole-src-4.2.12/src/core/array.c  -fPIC -DPIC -o src/core/.libs/array.o
In file included from /root/rpmbuild/BUILD/swoole-src-4.2.12/include/swoole.h:174,
                 from /root/rpmbuild/BUILD/swoole-src-4.2.12/src/core/array.c:17:
./swoole_config.h:22:2: error: #error "GCC 4.8 or later required."
make: *** [src/core/array.lo] Error 1


解决办法：
安装最新版本的swoole 提示

pecl install swolle 
...
GCC 4.8 or later required.
首先想到的时候yum更新gcc

yum install gcc
Package gcc-4.4.7-23.el6.x86_64 already installed and latest version
Nothing to do
已经是最新版本了，怎么办，只有找其它源了

curl -Lks http://www.hop5.in/yum/el6/hop5.repo > /etc/yum.repos.d/hop5.repo
yum install gcc gcc-g++
安装成功

gcc -v
gcc version 4.8.2 20131212 (Red Hat 4.8.2-8) (GCC)
