2015年12月15日 | 分类: 【技术】

【介绍】

LibGD 是一个开源的图像处理库,支持 PNG/JPEG/GIF以及其他格式的图像。GD一般被用来创建图表、图形、缩略图以及其他图像相关的处理操作。

官网:https://www.libgd.org/
源码:https://github.com/libgd/libgd/

【rpm安装最新版本gd(推荐)】

依赖:

yum install libwebp libwebp-devel libxml2 libxml2-devel zlib zlib-devel libpng libpng-devel freetype libjpeg libjpeg-devel libXpm libXpm-devel

下载:https://centos.pkgs.org/7/remi-x86_64/gd-last-2.2.5-8.el7.remi.x86_64.rpm.html
下载:https://centos.pkgs.org/7/remi-x86_64/gd-last-devel-2.2.5-8.el7.remi.x86_64.rpm.html

yum install http://rpms.remirepo.net/enterprise/7/remi/x86_64//gd-last-2.2.5-8.el7.remi.x86_64.rpm
yum install http://rpms.remirepo.net/enterprise/7/remi/x86_64//gd-last-devel-2.2.5-8.el7.remi.x86_64.rpm

如果报错:

Error: Package: gd-last-2.2.5-8.el7.remi.x86_64 (/gd-last-2.2.5-8.el7.remi.x86_64)
           Requires: libwebp.so.7()(64bit)

那么安装它:

下载:https://centos.pkgs.org/7/remi-x86_64/libwebp7-1.0.2-1.el7.remi.x86_64.rpm.html

yum install http://rpms.remirepo.net/enterprise/7/remi/x86_64//libwebp7-1.0.2-1.el7.remi.x86_64.rpm

如果报错:

Error: gd-last-devel conflicts with gd-devel-2.0.35-26.el7.x86_64

那么卸载它:

yum remove gd-devel

【yum安装】

问题:版本较低。

yum install libwebp libwebp-devel libxml2 libxml2-devel zlib zlib-devel libpng libpng-devel freetype libjpeg libjpeg-devel libXpm libXpm-devel gd gd-devel

【从源码编译安装】

问题:可能出现奇怪的环境问题。
