为Torch7 在ubuntu14.04 安装GraphicsMagick

一. 官网上下载安装包

https://sourceforge.net/projects/graphicsmagick/?source=typ_redirect

二. 进行安装

$ cd GraphicsMagick
$ ./configure '--with-magick=wand/GraphicsMagickWand-config' '--enable-shared'
说明：第一个with是生成libGraphicsMagickWand.so（可能默认没有生成这个，在lib里面确实没有看到这个库），
第二个with是生成共享库（默认可能是静态的吧，我开始没用第二个，得到的库后缀是.a）
$ make
$ sudo make install

$sudo echo “/usr/local/lib”
$sudo /sbin/ldconfig

至此安装成功

三. 测试

直接在shell测试

$ gm
