DDLab Cygwin readme: Sept 2015 update
-------------------------------------------------------------------
This version of DDLab was compiled in Windows 7 
for Cygwin/X, a Linux environment running in Windows.

ddlabz03_cygwin32.tar.gz unpack to give
ddlabz03_cygwin32.exe

Your Cygwin/X must have the default packages, 
and also xorg-x11-base, xorg-x11-devel, xorg-x11-fnts.

To run DDLab:
click on the Cygwin icon and enter "startx" to get a terminal, 
then from the directory with the DDLab files, 
enter the name of the executable preceded by ./ and followed by &

./ddlabz03_cygwin32 &

alternatively, first change directory to "ddfiles"
then enter the name of the executable preceded by ../ and followed by &

DDlab should run just like the Linux or Mac versions, though much slower.
-------------------------------------------------------------------

To compile DDLab:
Click the Cygwin icon.
Enter "startx", for the Cygwin terminal.
Change to the directory with the DDLab source code
and the Makefile, which is the same as for Linux.
Enter: "make -f Makefile_Linux_z03" (or the name of the Makefile)
If the compile is successful, ddlabz03.exe (or the file name set
in the Makefile) is created. Run as described above.
