问题描述

我在Ubuntu 14.04机器上安装了最新的Octave.但是，当我尝试运行imread命令时，它显示以下错误消息:

I installed latest Octave on Ubuntu 14.04 machine. However, when I tried to run imread command, it showed the following error message:

octave:12> imread('newfile.png')
error: imread: invalid image file: /usr/lib/x86_64-linux-gnu/octave/3.8.1/oct/x86_64-pc-linux-gnu/__magick_read__.oct: failed to load: /usr/lib/x86_64-linux-gnu/octave/3.8.1/oct/x86_64-pc-linux-gnu/__magick_read__.oct: undefined symbol: _ZN6Magick5ColorC1Ehhh

有人可以建议如何解决吗?

推荐答案

按照以下步骤为我工作[作者:ChristofferCronström(赞美)]:

Following these steps worked for me [Author: Christoffer Cronström (hymyly)]:

安装构建八度所需的dev软件包.

Install the dev packages needed to build octave.

sudo apt-get build-dep octave

获取官方源代码包.在干净的目录中执行此操作，因为它会被污染.

Get the official source package. Do this in a clean directory, because it will get polluted.

cd ~/some/suitable/directory
apt-get source octave

构建它.我大约花了一个小时.

Build it. This took roughly an hour for me.

cd octave-3.8.2
dpkg-buildpackage

从构建目录中运行它:

./run-octave

...或最优选将其安装在官方八度音阶上:

...or most preferably install it over the official octave:

cd ..
sudo dpkg --install octave_3.8.2-4_amd64.deb
