[ncl-talk] Cygwin issue (forked process died unexpectedly)

[Kevin Vermeesch]

Thanks for the response. Is there a difference between the Cygwin 
version and Cygwin's setup.exe version? The output of uname -a on 
Cygwin's command line is:
CYGWIN_NT-6.1-WOW GS612-KCV1WL 2.1.0(0.287/5/3) 2015-07-14 21:26 i686 Cygwin
but the 2.738 you mentioned is a version of the setup.exe file.

The system above is Windows 7 64-bit. For what it's worth, I installed 
NCL on my personal computer (Windows Vista 32-bit) and NCL 6.3.0 works 
fine on there. That computer is running a slightly older version of 
Cygwin. The output of uname -a on that system is:
CYGWIN_NT-6.0 Kevin-PC 1.7.35(0.287/5/3) 2015-03-04 12:07 i686 Cygwin

It must be something with the new/latest Cygwin version that is causing 
the problem(?). Before the last Cygwin upgrade on the Windows 7 computer 
it was working fine on there too.
thanks,
Kevin
