PHP添加GD库支持的步骤详解

[root@jbxue ~]# rpm -qa | grep zlib
zlib-1.2.1.2-1.2
zlib-devel-1.2.1.2-1.2
You have new mail in /var/spool/mail/root

不存在的话，请手动下载编译：http://ishare.iask.sina.com.cn/f/15275772.html

tar zxvf zlib-1.2.2.tar.gz
  cd zlib-1.2.2
  ./configure
  make
  make install

2，安装libpng http://sourceforge.net/projects/libpng/

tar zxvf libpng-1.4.2.tar.tar
  cd libpng-1.4.2
./configure
  make
  make install

3.安装freetype http://sourceforge.net/projects/freetype/

tar zxvf freetype-2.3.12.tar.gz
  cd freetype-2.3.12
  ./configure
  make
  make install

4，安装Jpeg http://www.ijg.org/

tar zxvf jpegsrc.v8b.tar.gz
  cd jpeg-8b/
  ./configure --enable-shared
  make
  make test
  make install

注意，这里configure一定要带--enable-shared参数，不然，不会生成共享库。

5，安装GD https://bitbucket.org/pierrejoye/gd-libgd/downloads

tar zxvf gd-2.0.33.tar.gz
  cd gd-2.0.33
  ./configure --with-png --with-freetype --with-jpeg
make
make install

6，安装PHP php-5.2.11.tar.gz

tar zxvf php-5.2.11.tar.gz
cd php-5.2.11
./configure选项见下方
make
make install

注：

/usr/local/include/freetype2/freetype
freetype
/usr/local/include/include
t1lig
/usr/local/include/libpng14/
png
/usr/local/include
jpeg
[root@jbxue php-5.2.11]# ./configure --help | grep t1lib
  --with-t1lib[=DIR]        GD: Include T1lib support. T1lib version >= 5.0.0 required
[root@jbxue php-5.2.11]# ./configure --help | grep png
  --with-png-dir[=DIR]      GD: Set the path to libpng install prefix
[root@jbxue php-5.2.11]# ./configure --help | grep jpeg
  --with-jpeg-dir[=DIR]     GD: Set the path to libjpeg install prefix
[root@jbxue php-5.2.11]# ./configure --help | grep freetype
  --with-freetype-dir[=DIR] GD: Set the path to FreeType 2 install prefix
[root@jbxue php-5.2.11]#
./configure --prefix=/opt/php5 --with-apxs2=/opt/apache/bin/apxs --with-mysql=/usr/local/mysql --with-config-file-path=/opt/php5/lib --with-gd --with-zlib --with-png-dir=/usr/local/include/libpng14/  --with-jpeg-dir=/usr/local/include  --with-freetype-dir=/usr/local/include/freetype2/freetype （--with-t1lib  --with-t1lib-dir=/usr/local/include/include）

最后只有T1Lib Support没有启用。

GD库支持最终如下：

Listen 81
#
# Dynamic Shared Object (DSO) Support
#
# To be able to use the functionality of a module which was built as a DSO you
# have to place corresponding `LoadModule' lines at this location so the
# directives contained in it are actually available _before_ they are used.
# Statically compiled modules (those listed by `httpd -l') do not need
# to be loaded here.
#
# Example:
# LoadModule foo_module modules/mod_foo.so
LoadModule php5_module        modules/libphp5.so
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
#

在htdocs目录中创建测试文件info.php：

[root@jbxue apache]# cat htdocs/info.php

 echo phpinfo();
?>

然后，在浏览器中访问该文件，可查询GD库支持的情况。
