编译php的时候遇到的问题：

编译代码：

./configure --prefix=/server/php-5.4-nginx --with-config-file-path=/server/php-5.4-nginx --with-mysql=/server/mysql-5.5/ --with-mysqli=/server/mysql-5.5/bin/mysql_config --with-iconv-dir --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-fpm --enable-mbstring  --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets  --with-xmlrpc --enable-zip --enable-soap  --with-mcrypt=/usr/local/

报错信息：configure: error: Please reinstall the libcurl distribution -

    easy.h should be in /include/curl/

解决办法：yum install curl-devel

再次编译报错：

configure: error: jpeglib.h not found.

解决方法：

检查之后发现已经安装了libjpeg

[root@localhost php-5.2.14]# yum list installed|grep libpng
libpng.x86_64           2:1.2.49-1.el6_2

或者：

[root@localhost php-5.2.14]# rpm -qa|grep libjpeg
libjpeg-turbo-1.2.1-3.el6_5.x86_64

如果没有安装则需要：

yum install libjpeg libpng freetype libjpeg-devel libpng-devel freetype-devel -y

若是64位系统
解决方法：
yum install libjpeg.x86_64 libpng.x86_64 freetype.x86_64 libjpeg-devel.x86_64 libpng-devel.x86_64 freetype-devel.x86_64 -y

安装完后再安装libjpeg-devel

安装libjpeg-devel

yum -y install libjpeg-devel

记住一点就好了：编译过程中出现错误不可怕，出现一个解决一个就好了。
