Create a file called 'stderr.c':

int
main(int argc, char **argv)
{
  dup2(1, 2);
  argv++;
  execvp(*argv, argv);
  perror(*argv);
  exit(1);
}

Compile this:

gcc -o stderr -g stderr.c

The program stderr will redirect all error output to the same place as
stdout:

stderr gcc -c stderr.c > gcc.out

This will probably only work with cygwin.dll programs, though.

Can you give me a quick hint what the small program 
mentioned in point no. 2 would look like.
How would I invoke this to re-direct the output of GCC 
to a file.

Thanks,
Mark.

This works in NT3.51 also.  I stumbled upon it 
accidentally when I was trying to redirect stdout 
of an executable with a final argument of '2' 
and redirected stderr instead!

This works with NT4.0 cmd.exe only, but not with 95's command.com.

Right.  Sorry to have not mentioned that.

Other alternatives are:

1) Use 4DOS ( http://www.jpsoft.com ), which allows '>&' for redirection.

2) Write a small program to redirect stderr to stdout and run its
   arguments.

3) bash -c 'exec gcc whatever 2>wherever'

Just to follow up on my own points:  The command I gave originally
does work on NT 3.51.  That's all I'm running here.

Someone asked for the small program.  This is it:

Create a file called 'stderr.c':

int
main(int argc, char **argv)
{
  dup2(1, 2);
  argv++;
  execvp(*argv, argv);
  perror(*argv);
  exit(1);
}

Compile this:

gcc -o stderr -g stderr.c

The program stderr will redirect all error output to the same place as
stdout:

stderr gcc -c stderr.c > gcc.out

This will probably only work with cygwin.dll programs, though.

In a vain attempt to hold off on future messages, I'd like to point out
that I know that it is possible to make this into a much more sophisticated
program which takes an argument signifying a file for the stderr output.
It is possible to augment this program to shine your shoes and walk the dog.
There are undoubtedly much more sophisticated programs out there which
will do exactly what is required and do it intuitively without even the
necessity of typing the command at all.

Personally, I would again strongly suggest that anyone who can't use
bash for this should consider 4DOS.  It is a wonderful command line
shell which provides you all sorts of advanced capabilities lacking in
command.com or cmd.exe.

RE: Redirect the stderr GCC stream to file, executing from Ms-Dosshell

[Rick Frink]

Hello,

  A related question, I think.  Once I have an executable, in the NT 4.0
environment, is it possible to redirect stdout ?  The problem that I've
run into is that I am executing a command from the NT PerfMon, but it
insists upon flashing a DOS window on screen...I even put my executable
in an NT CMD batch file, but it does not help.
Any clues ?
Thanks, in advance.

Rick Frink
