   Use cygwin perl and setup your path correctly. Then
        system("make all")

  If there's some reason you think you can't use cygwin perl try

    system("cmd/c do_my_make.bat")

 take a peak at your c:\cygwin\cygwin.bat for hints on what
 to put in my_make.bat

The description of "failing" does not really provide enough information
to debug the problem.

I assume, however, that if you avoid using a Cygwin path in the system
command, things will work better:

system("c:/cygwin/bin/make all")

It sounds like you're using a non-cygwin version of perl.

perl/cygwin and system calls

[Perakis, John]

     Let me see if I can pose the question correctly.    I would like to
use a cygwin environment from a perl script.    I have a build
environment that works in a cygwin window.  What I'm in the process of
trying to do is write a perl script that can be  started from the Task
Scheduler.  The perl script cd to a directory and cvs co a module.  Once
the module is checked out I'm trying to use a system call to kick off my
make  ie system("//c/cygwin/bin/make all").  This piece is failing, I
believe,  because the system call is going out and using an NT
environment not a Cygwin env.  Does anyone know how I can get this to
what I want.

Thanks,
John

Is your Perl Cygwin-ized or is it the Win32 model?  Why do you use the 
deprecated //<drive> syntax?  You should use "/cygdrive/c" or a mount.
