执行make后出报错：
/usr/local/zlib/lib/libz.a: could not read symbols: Bad value
make: *** [libphp5.la] Error 1
解决办法：
cd zlib-1.2.3 //进入zlib目录 CFLAGS="-O3 -fPIC" ./configure //使用64位元的方法进行编译 make make install make clean
注意：如果./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache/bin/apxs --with-mysql=/usr/local/mysql --with-gd=/usr/local/libgd --enable-gd-native-ttf --with-ttf --enable-gd-jis-conv --with-freetype-dir=/usr/local/freetype --with-jpeg-dir=/usr/local/libjpeg --with-png-dir=/usr --with-zlib-dir=/usr/local/zlib --enable-xml --enable-mbstring --enable-sockets--with-snmp --enable-short-tags后提示错误，说不支持snmp，我们可以先安装net-snmp，然后再指定路径
