Hello, 

      I'm learning c++, and I'm using djgpp and bcc. The first
      program I wrote, called test.cc reads:

#include <iostream.h>

void main() {

	cout << "Hallo";

}

      It compiles fine with bcc. However, gcc, no. It doesn't 
      compile. When I type at the command prompt:


redir -o stdout -e stderr gcc -v test.cc -o test.exe

   
      I get the stderr:

      I don't understand the last errormessages "undefined ref.
      to 'cout'"??? This is c++ isn't it? Other c++
      constructions like:  for ( int a=1; a<2; a++ ) etc. work
      fine. I tried already using #include <stream.h> in stead
      of iostream.h. Anybody know what I do wrong???

      I include some stuff here: my autoexec.bat:

      The output of go32-v2:

Usage: go32 coff-image [args]
Rename this to go32.exe only if you need a go32 that can run v2 binaries as
 well as v1 binaries (old makefiles).  Put ahead of the old go32 in your PATH
 but do not delete your old go32 - leave it in the PATH after this one.
Set GO32_V2_DEBUG=y in the environment to get verbose output.

      Hope somebody can help me...., please mail.
