无法使用jre 1.7.0_05在科学版Linux上启动MATLAB guis(GUIDE) [英] Cannot launch MATLAB guis (GUIDE) on scientific linux with jre 1.7.0_05

问题描述

问题:GUIDE guis缺少其通常的功能(下拉菜单，按钮等).它们只是显示为带有边框的空窗口，边框描述了不同按钮的位置.该问题似乎与我使用的jre版本有关.我不知道该怎么办.

这是matlab使用的环境变量. /usr/java/default指向jre_1.7.0_05的根目录，其中包含bin，lib等.

解决方案

MATLAB的底线是Java 7打破了很多东西，恢复到最新的Java 6(您可以同时安装两个). /p>

只需设置$MATLAB_JAVA环境变量即可指向JRE6安装.

Problem: GUIDE guis are missing their usual features (drop-down, push-buttons, etc). They just appear as empty windows with borders delineating where the different buttons used to be. The issue appears to be related to the jre version I am using. I don't know how to proceed.

Here's the environment variables matlab is using. /usr/java/default points to the root directory of jre_1.7.0_05 contain bin, lib etc.

解决方案

Bottom line is a lot of things in MATLAB break with Java 7, revert back to latest Java 6 (you can have both installed at the same time).

Just set $MATLAB_JAVA environment variable to point to a JRE6 installation.
