第一次编译安装PHP的时候很顺利，因为要增加freetype，所以要重新编译，结果死活就是无法通过configure。

centos7信息

uname -a

Linux dev 3.10.0-327.el7.x86_64 #1 SMP Thu Nov 19 22:10:57 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

运行 ./configure 报错

configure: error: cannot run C compiled programs.

If you meant to cross compile, use `--host'.

运行 grep error config.log

cc: error: unrecognized command line option '-V'

cc: fatal error: no input files

cc: error: unrecognized command line option '-qversion'

按照网上说的方法 在configure后面加上了 --host=x86_64 ，报错

configure: error: in `/usr/local/src/php-5.6.19':

configure: error: C preprocessor "/lib/cpp" fails sanity check

config.log中错误提示，差好几个头文件
