[GRASS5] February 19, 2001 Cygwin build

[Malcolm Blue]

Mike,

 From my experience trying to run the XDRIVER on Win98 I suspect your 
problems are caused by poor process management with Cygwin/Win98.  
XDRIVER and CELL run OK with Cygwin/WinNT, but I was unable to get the 
XDRIVER running on Win98 (I didn't try CELL at the time).  Since both 
use fork(), I suspect they are doing something in that implementation 
that doesn't work reliably on Win 98. 

When I start the XDRIVER using d.mon start on WinNT, the XDRIVER.exe is 
listed in the process list from the ps command.  When I tried the same 
thing on Win98, it seemed to start the XDRIVER, but then issued some 
error messages (IPC version messages). The ps command did not list the 
XDRIVER.exe process.

Unfortunately a number of Cygwin API calls work on WinNT that don't work 
on Win98.  I'm able to run both IPC and socket version of GRASS on WinNT.

Sorry I couldn't give you better news, but I think its a cygwin/Win98 
problem. 

Malcolm
