This seems like a pretty non-standard installation already.

Installation must have failed, or you have not followed the
instructions. How did you call configure, when building gcc? What does
g++ -V say?

BTW iostream.h is deprecated. When found, it provides iostreams in the
global namespace, not in the std namespace. So using std::cout in your
code would have failed anyway. This can be said without seeing the
source.

Should never be necessary. I've built gcc many times over the years
according to the docs and never had problems like this.
