编译php5.4的时候出现错误----configure: error: in `/usr/local/src/php540/php-5.4.0':

错误如下：
checking for grep that handles long lines and -e... /bin/grep
checking for egrep... /bin/grep -E
checking for a sed that does not truncate output... /bin/sed
checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking target system type... x86_64-unknown-linux-gnu
checking for cc... cc
checking whether the C compiler works... no
configure: error: in `/usr/local/src/php540/php-5.4.0':
configure: error: C compiler cannot create executables
See `config.log' for more details.
分析，百度了很长时间终于发现，原来是缺少gcc
所以：
yum  install -y gcc就可以了
