Embarassing question on linking

Now under hello.c, I have no errors,ÃÂ I'm guessing that I need to do
something to link the correct libraries which are needed under (G)C++, and were
included by default under GCC (ansi).
----
1. use g++ instead of gcc
2. use void if the function does not
return anything. ( the default return type is int if not
specified)
The following is the similar code
compiled and run in my Windows 95:
//g/tmp/tmp ) cat hello.cpp
#include <iostream.h> ÃÂ
void main()
{
cout << "Hello there GNU++ world!" << endl;
}
//g/tmp/tmp ) g++ -o hello.exe hello.cpp
//g/tmp/tmp ) hello
Hello there GNU++ world! ÃÂ
Sincerely,
Wei Ku

Subject: Embarassing question on linking
I am learning C++ using cygwin32, so I am not too well
versed in these
unix type utilities (previous experience with IDE based products).
I'll cut to the chase..ÃÂ hello world based C++ program yields the
following:
The code:
bash$ cat hellopp.cc
#include <iostream.h>
main()
{
ÃÂ ÃÂ ÃÂ ÃÂ ÃÂ ÃÂ ÃÂ cout << "Hello there GNU++
world!\n";
}
bash$
The error:
bash$ make -f hellopp.mak
/gnuwin32/b18/H-i386-cygwin32/bin/gcc.exe -pedantic -o hellopp.exe
hellopp.cc
C:\TEMP\cc0010051.o(.text+0x2a):hellopp.cc: undefined reference to
`cout'
C:\TEMP\cc0010051.o(.text+0x2f):hellopp.cc: undefined reference to
`ostream::ope
rator<<(char const *)'
gcc.exe: Internal compiler error: program ld got fatal signal 1
make: *** [hellopp.exe] Error 1
Thanks

(Yes, I am reading the notes at cygnus, and am looking into
prep.mit.edu)
