装了个Octave

装了个Octave,用来做些题目。但是遇到了一些问题,结果不是很理想。

先是在Linux下装的。用的Gentoo,有些USE是去掉的。于是乎,最后装好的样子就是不能生成图形,也不能看help。不能生成图形是有心理准备的,因为我的Gentoo连X都没装,gtk 和 qt 也都是去掉的。不能生成help则是因为doc这个USE Flag被去掉了。如果加回去,则需要装很大一堆包,包括几个X的和几个Tex的,感觉太小题大做了。

于是,加上看着这个软件的计算功能还不错,本着用来代替Windows自带计算器的想法,准备装到Windows上去。我用的Windows8,使用了那个for VS2010的setup.exe来安装。装好后不能用…… 一查,发现这个在Windows8下还需要做点fix,需要在启动的时候加一个 -i --line-editing。 于是乎,加了,然后再打开。这下基本可以正常用了。可惜,想用于代替calc还是不太靠谱。原因无它,速度太慢了。打开慢,生成图像也慢。几十秒才能出结果,这简直无法接受。

但是我看别人好像并没有遇到“慢”的问题。不知道原因何在。是因为Windows8?还是因为我的jre不太对?我的jre装完后,只能执行java,一旦输入java -v 会直接告诉你不能生成VM,让人很囧。

我还有一台Windows8.1的机器,一会去试试看能否有改观。
