Re: problems installing openmpi_ext

Hello,

Thanks to both of you for looking into this.  I am happy to try this in the 
debugger but I admit that I've never used it before and I'm having problems 
getting started. 

First, you don't mean to use the debugger in octave I bather?  I tried starting 

octave --debug

and that give a lot of output, none of which seemed at all useful.

Second ,you suggest running octave in a debugger and show 'run-octave -g'.  I 
did not know you could run octave in a debugger and am not sure exactly how to 
do that.  If you could get me started I'm happy to share the output.

Thanks again,
Francis
