This looks like you did not do a "make clean" before trying to compile with
your new configuration. If you change to a new compiler, you need to do this
to remove all the old compiled objects.

Looks pretty bad: are you sure your gcc/g++ installation is functional (i.e.
can you compile other types of C++ code?

Try typing "g++ -v -c" and looking at the output. It will have
a section entitled "#include <...> search starts here:", followed by the
actual locations where it is searching for <fstream>, <string>, <iostream>,
etc. Bascially, if your g++ compiler can't find <iostream>, it is seriously

...good luck...dac
