Subject: Embarassing question on linking

I am learning C++ using cygwin32, so I am not = too well=20 versed in these
unix type utilities (previous experience with IDE based products).

I'll cut to the chase.. hello world based C++ program yields = the
following:

The code:

bash$ cat hellopp.cc
#include <iostream.h>

main()
{
cout << "Hello = there GNU++=20 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
