Cannot compile with GCC-4.0

[Zingam]

The compiler cannot find the <iostream> header, and when I type <iostream.h> it reports that it is depricated but cannot link the compiled objects.

C can be compiled normally but not C++. I have installed everything via Synaptic, that is necessary.

How should I install GCC properly?

[thumper]

sudo apt-get install build-essential

I have installed build-essentials already. It doesn't work yet.

Try reinstalling libstdc++6-4.0-dev.
