# Trying to generate a loadable module for Tcl/Tk8.1.1 on
# WindowsNT using Cygwin20 cross-compiler running under
# RedHat6.0.

# Step -1:
# Make a copy of winsock.h into winsock2.h.  "Winsock2.h" is needed by 
# tclWinPort.h.  tclWinPort.h is included by tclStubLib.c in step 3.
#

# Step 0:
# Make sure the cross-compiler tools are on PATH and remove
# old files.
#
PATH=$PATH:/opt/cygwin20/bin
rm -f simple.o stublib.o simple.dll

# Step 1:
# Generate the C source code into "simple.c"
#
cat >simple.c <<\END

  Tcl_InitStubs(interp,"8.1",0);

  -I/home/drh/tcltk/tcl8.1.1/generic \
