Compilation error in CoWare SPD (2006) on Ubuntu 7.04

Hi,

I am running CoWare SPD (2006 version) on Ubuntu 7.04. However, when I try to run the simulation of even demo programs on the tool, I get a code-compilation error from the tool. Could you please help me in troubleshooting the error?

The sequence of steps that I follow is:

1. Start SPD : spd &
2. Load a design example : Reference Designs -->Interactive DSP Examples -->Frequency Response of a Variable Low Pass Filter.
3. Start a New Flow : Flows --> New Flow
4. Start Simulation : Flows --> Start

At this stage, various messages can be seen in the message window:

I think the above issue is because the tool is not able to find the lstdc++ package which is a part of g++ package.

Could anybody tell me a way to tell the tool where to look for g++ packages?
There is an option of setting environment variable LD_LIBRARY_PATH in the .bashrc file but it does not seem to work.

One more thing, I was not able to find this package lstdc++ on my machine. Could anybody tell me where this package is found?

Thanks a lot!
