文档介绍：首先安装GD库及GD库关联程序
yum -y install \
libjpeg-devel \
libpng-devel \
freetype-devel \
zlib-devel \
gettext-devel \
libXpm-devel \
libxml2-devel \
fontconfig-devel \
openssl-devel \
bzip2-devel
tar xzvf gd-
cd gd-(cd /opt/gd//)
./configure --prefix=/usr/local/gd
make && make install
----------PHP源码目录下------------
./configure \
--prefix=/usr/local/php \
--with-apxs2=/usr/local/apache/bin/apxs \
--with-gd=/usr/local/gd \
--with-mysql=/usr/local/mysql \
--with-config-file-path=/etc \
--enable-sqlite-utf8 \
--with-zlib-dir \
--with-libxml-dir \
--with-freetype-dir \
--with-jpeg-dir \
--with-png-dir \
--with-ttf \
--with-iconv \
--with-openssl \
--with-gettext \
--enable-mbstring \
--enable-gd-native-ttf \
--enable-gd-jis-conv \
--enable-static \
--enable-zend-multibyte \
--enable-inline-optimization \
--enable-sockets \
--enable-soap \
--enable-ftp \
--disable-ipv6
make && make install
-------make过程中出错解决办法--------
vi /usr/local/gd/include/
