1. 下载GraphicsMagick,官方FTP下载地址:ftp://ftp.graphicsmagick.org/pub/GraphicsMagick/GraphicsMagick-LATEST.tar.gz

 LATEST是最新版本的意思,所以当前我现在最新的版本是1.3.28。


2. 下载完成后解压压缩包

tar -zxvf GraphicsMagick-LATEST.tar.gz

3. 进入解压目录(解压后目录名称跟版本有关,根据实际目录进入)

cd GraphicsMagick-1.3.28

4. 安装扩展

yum install gcc gcc-c++ libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libwebp-devel libwebp

5. 编译GraphicsMagick

./configure  --prefix=/opt/GraphicsMagick

查看返回结果,确保我下面标记红色的栏目是yes的
