Hello!

From the manual:

-----

By default, configure picks c++ as the compiler name and GNU c++ links
with -lg++. If you are using gcc, that behavior can cause problems
during configuration such as this:

configure: error: installation or configuration problem: C++ compiler
cannot create executables.

You might also observe problems during compilation related to g++,
libg++ or libstdc++. One cause of these problems is that you may not
have g++, or you may have g++ but not libg++ or libstdc++. Take a look
at the `config.log' file. It should contain the exact reason why your
c++ compiler didn't work! To work around these problems, you can use
gcc as your C++ compiler. Try setting the environment variable CXX to
"gcc -O3". For example:

shell> CXX="gcc -O3" ./configure 

This works because gcc compiles C++
sources as well as g++ does, but does not link in libg++ or libstdc++
by default. Another way to fix these problems, of course, is to
install g++, libg++ and libstdc++.
