[GRASS5] Win32 compile with cygnus ...

[Andreas Lange]

Hi John, Hi Markus, Hi Grasslist,

i finished a compile with the latest cygwin setup on NT 4.0 SP 5 in this
minute.
I can now compile all modules from the standard GRASS list file
(including r.in.png and r.out.png). 
I'll check in my changes to the CVS in the next days. I'll check in my
head file too.

I have now a running X11R6.4 installation, but can not start grass5 in
the xterm. But i managed somehow to start xwin from the grass shell
prompt. 

_But_ the problem still remains that there is no graphical output yet.

After some code modifications i can now even compile the new IPC message
queue setup, but this still requires a lot of work to be done.

I would vote for dropping support for Windows 95/98 because the new
X11R6.4 port for windows with the cygnus tools will not work with Win9x.
The X11 programs are linked dynamically to the X11R6 libraries, so that
there is no chance to get this to work with the commercial X Servers
(e.g. MI/X), as they are based on X11R5. The usage of the X11 port for
the B20 version of the cygnus tools under the current V1.1 is not
supported. 

>From my initial testing i can say that there are waiting some nasty
surprises, so that i would not recommend the download of the GRASS
binaries for cygwin to people who are not of the adventurous nature. And
the missing graphical output (the CELL and HTMLMAP driver depend on the
missing fifos!) and the mangled bash setup makes it a pain to work with.
Just as a warning, so that no false expectations arise. 

How can we get graphical output and tcltkgrass running under this setup?
I can still not say if i can get the X monitor to work and if tcltkgrass
will work under the X11 Window Setup. I have the initial impression that
the X11 Setup is not for real work (it is a beta!). 

If someone has ideas how we can get a windows port with graphical
output, please tell!

cu,

Andreas
