Embedded Command Shell and DS-5

Hallo altogether,

I have a problem with de SoC-EDS-Software with Linux (Ubuntu). When I start the embedded command shell, I get the message

Could not find DS-5 installation.

This is a problem afterwards, because when I start eclipse, there are no Altera-specific additions like the debugger. DS-5 is in /usr/local/DS-5. I also added this path to the $PATh-Variable.

I don't know, what's going wrong. I hope that anyone can give me a hint!

Thanks very much for helping!

Sebastian
