Re: [Sheflug] c++ & mem

[Ian Porter <nospam [at] uea.ac.uk>]

Thanks for the reply Jose.  

The URL place was very helpful cheers, but the g++/c++ thing still does
not work.  I had also tried it with the "-o" but still nothing.
The problem started when the OS crashed on me. So I reinstalled
linux and now the g++ does not work.

Thanks
Ian
