php编译gd支持验证码登陆

问题是脚本编译的php不支持gd，不能生成动态的验证码？


最终的解决办法是：

1.确定gd，jpeg，png，freetype包都已经安装（基于centos6.7 yum安装）

[iyunv@mcd nginx+php1.9]# rpm -qa | grep jpe

libjpeg-turbo-1.2.1-3.el6_5.x86_64

libjpeg-turbo-1.2.1-1.el6.x86_64

openjpeg-libs-1.3-11.el6.x86_64

libjpeg-turbo-devel-1.2.1-3.el6_5.x86_64

[iyunv@mcd nginx+php1.9]# rpm -qa | grep png

libpng-1.2.49-2.el6_7.x86_64

libpng-devel-1.2.49-2.el6_7.x86_64

libpng-1.2.49-1.el6_2.x86_64

[iyunv@mcd nginx+php1.9]# rpm -qa | grep freetype

freetype-devel-2.3.11-17.el6.x86_64

freetype-2.3.11-17.el6.x86_64

[iyunv@mcd nginx+php1.9]# rpm -qa | grep gd

2.编译安装，注意标红的字体

./configure --prefix=/opt/php --with-config-file-path=/opt/php/etc/php5 --with-mysql=mysqlnd --with-pdo-mysql=mysqlnd --with-iconv-dir --with-zlib --with-libxml-dir --enable-xml --enable-magic-quotes --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-fpm --enable-force-cgi-redirect --enable-mbstring --with-mcrypt --enable-ftp --with-gd --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --without-pear --with-gettext --with-mime-magic --with-freetype-dir --with-jpeg-dir --with-png-dir

make

make install
