It isn't the installing part.

It's a common mistake among newbies, you should link the library
for the functions you use. In this case you should compile your program
with
gcc -o file.exe file.cc -liostream
or (which does the equivalent)
gxx -o file.exe file.cc

this is because the linker doesn't know anything about the
implementation of 'cout <<' which is in libiostream.a
(you don't need it -lc for c/c++ programs, because libc is linked in
by default.)
Remember to put the libraries to be linked into your program as the
last parameters in your command line.

hth,
 Robert
