不重新编译PHP文件的情况下php GD库扩展库的编译安装(centos)

iszjw

　　gd-2.0.33.tar.gz http://www.boutell.com/gd/
jpegsrc.v6b.tar.gz http://www.ijg.org/
libpng-1.2.7.tar.tar http://sourceforge.net/projects/libpng/
zlib-1.2.2.tar.gz http://sourceforge.net/projects/zlib/

　　freetype-2.1.9.tar.gzhttp://sourceforge.net/projects/freetype/
　　



1、安装 zlib


wget ftp://ftp.sunfreeware.com/pub/freeware/SOURCES/zlib-1.2.3.tar.gz


tar -zxf zlib-1.2.3.tar.gz


cd zlib-1.2.3


./configure --prefix=/usr/local/zlib


make


make install




2、安装 jpeg


wget ftp://ftp.sunfreeware.com/pub/freeware/SOURCES/jpeg.tar.gz
安装前先创建jpeg安装文件所需(如下)目录，防止提示类似“无法创建一般文件‘/usr/local/jpeg/***’: 没有那个文件或目录" 的错误


mkdir /usr/local/jpeg


mkdir  /usr/local/jpeg/bin


mkdir  /usr/local/jpeg/lib


mkdir  /usr/local/jpeg/include


mkdir  /usr/local/jpeg/man


mkdir  /usr/local/jpeg/man1


mkdir  /usr/local/jpeg/man/man1


tar -zxf jpeg.tar.gz


cd jpeg-6b


./configure --prefix=/usr/local/jpeg --enable-shared --enable-static


make


make install




安装完成提示：


Libraries have been installed in:


/usr/local/jpeg6/lib
　　
　　3、安装 libpng



wget ftp://ftp.sunfreeware.com/pub/freeware/SOURCES/libpng-1.2.16.tar.gz


tar -zxf libpng-1.2.16.tar.gz


cd libpng-1.2.16


./configure --prefix=/usr/local/libpng


make


make install



4、安装 freetype


wget http://download.savannah.nongnu.org/releases/freetype/freetype-2.3.4.tar.gz


tar -zxf freetype-2.3.4.tar.gz


cd freetype-2.3.4


mkdir -p /usr/local/freetype


./configure --prefix=/usr/local/freetype


make


make install



5、安装 GD


wget ftp://ftp.sunfreeware.com/pub/freeware/SOURCES/gd-2.0.33.tar.gz


tar -zxf gd-2.0.33.tar.gz


cd gd-2.0.33


mkdir -p /usr/local/gd2
./configure --prefix=/usr/local/gd2 --with-jpeg=/usr/local/jpeg/ --with-png=/usr/local/libpng/ --with-zlib=/usr/local/zlib/ --with-freetype=/usr/local/freetype/


make
make install
(如果出错见下文)
6、集成PHP GD扩展 到PHP里
切换到PHP源码包


如果已经安装
php，建议通过追加编译安装



进入“[php解压目录]/ext/gd”目录，执行如下命令：


[php安装目录]/bin/phpize


Java代码  


./configure --with-php-config=[php安装目录]/bin/php-config --with-jpeg=[jpeg-6b安装目录] --with-png=[libpng安装目录] --with-freetype=[freetype安装目录] --with-zlib=[zlib安装目录] --with-gd=[gd安装目录]
(如果出现未知配置项--with-png**,--with-freetype之类的错误 在配置项后面加上-dir参数即可：既修编译参数为： ./configure --with-php-config=[php安装目录]/bin/php-config --with-jpeg-dir=[jpeg安装目录] --with-png-dir=[libpng安装目录] --with-freetype-dir=[freetype安装目录] --with-zlib=[zlib安装目录] --with-gd=[gd安装目录] 即可
)


make  


make install  




安装成功后会在“[php安装目录]/lib/php/extensions/no-debug-non-zts-20060613”目录下生成gd.so文件，


   然后cp [php安装目录]/lib/php/extensions/no-debug-non-zts-20060613/gd.so /opt/php/ext




修改php.ini文件加载gd组件，添加extension_dir=/opt/php/ext和extension=gd.so，如果有extension_dir=/opt/php/ext则不需要增加


Java代码  


extension_dir=/opt/php/ext  


extension=gd.so  

./configure --with-php-config=/usr/local/php/bin/php-config --with-jpeg-dir=/usr/local/jpeg --with-png-dir=/usr/local/libpng --with-freetype-dir=/usr/local/freetype --with-zlib-dir=/usr/local/zlib --with-gd=/usr/local/gd2
执行编译安装


make


make install
具体操作流程如下:


$ cd <php源码>/ext/gd
$ /usr/local/php5/bin/phpize
$ ./configure --with-gd=/usr/local/gd --with-jpeg-dir=/usr/local/jpeg --with-png-dir=/usr/local/libpng --with-freetype-dir=/usr/local/freetype --with-zlib-dir=/usr/local/zlib --with-php-config=/usr/local/php/bin/php-config
$ make && make install
修改php.ini
$ make && make install
添加extension=gd.so
最后，重启apache

可能出现的错误以及解决方法：
编译GD库时如果出现以下错误：

make[1]:正在离开目录 `/usr/local/src/modules/gd-2.0.35&prime;
make: *** [all] 错误 2很显然，这是引入png库出现的问题，解决方法进入gd源代码目录：vi gd_png.c将16行的png.h修改成 libpng安装目录/include/png.h我这边就是：/usr/local/libpng/include/png.hmake && make install 成功

　　在安装php GD扩展时，报如下错误

　　gdIOCtx结构中增加void *data;

　　{
　　int (*getC) (struct gdIOCtx *);
　　int (*getBuf) (struct gdIOCtx *, void *, int);
　　void (*putC) (struct gdIOCtx *, int);
　　int (*putBuf) (struct gdIOCtx *, const void *, int);
　　/* seek must return 1 on SUCCESS, 0 on FAILURE. Unlike fseek! */
　　int (*seek) (struct gdIOCtx *, const int);
　　long (*tell) (struct gdIOCtx *);
　　void (*gd_free) (struct gdIOCtx *);
　　   void (*data);
　　}
　　gdIOCtx;


注:不知道是不是动态扩展gd的原因, 这个时候访问服务器并不能打开网页, 查找apache error_log, 上面写着:
/usr/local/apache//bin/httpd: symbol lookup error: /usr/local/php5/lib/php/extensions/no-debug-zts-20100525/gd.so: undefined symbol: gdJpegGetVersionString
和
/usr/local/apache//bin/httpd: symbol lookup error: /usr/local/php5/lib/php/extensions/no-debug-zts-20100525/gd.so: undefined symbol: gdPngGetVersionString
在网上找了好长时间, 找不到解决这个问题的办法, 或者这个问题引起的原因, 我想到了一个办法作为临时的解决办法:修改gd.c
$ vi $ cd <php源文件>/ext/gd/gd.c
/*
在这个文件的下面添加
# include <{libpng安装目录}png.h>
# include <{libjpeg安装目录}jpeglib.h>
const char * gdJpegGetVersionString()
{
           switch(JPEG_LIB_VERSION) {
                   case 62:
                           return "6b";
                           break;
                   default:
                           return "unknown";
           }
}
const char * gdPngGetVersionString()
{
          return PNG_LIBPNG_VER_STRING;
}
*/
然后重新整合php & gd, 问题解决,可以生成验证码.
