Yes, it's the same piping problem of three years ago. At the time the Geomview community wondered if this was the shape of things to come for piping and IPC in general, and if Geomview would need fixing for all platforms. But since 32-bit and 64-bit Cygwin differed, and OpenGL didn't work on 64-bit Cygwin either, making 32-bit the obvious choice to use, masterful inaction was the result. Wait and see how 64-bit Cygwin shakes out...
Three years on, 64-bit Cygwin is still the outlier; piping works everywhere else, 32- and 64-bit. It would be good to have 64-bit Cygwin work with Geomview and its modules, particularly since 32-bit OpenGL seems less than reliable (as also shown by the weird things seen on Raspbian on the Pi). It would also be good if Geomview was in the Cygwin installer, as compiling it is not easy for many; it's already a Debian package. But I don't personally have the technical piping or Cygwin-specific knowledge to troubleshoot this one, other than providing and maintaining the installation hints at http://sat-net.com/L.Wood/software/SaVi/building-under-Windows/ thanks Lloyd Wood http://savi.sf.net/ (that screenshot comes from 32-bit Cygwin, btw.) ----- Original Message ----- From: Jon Turney <jon.tur...@dronecode.org.uk> To: cygwin@cygwin.com Cc: lloyd.w...@yahoo.co.uk Sent: Monday, 20 June 2016, 22:58 Subject: Re: [ANNOUNCEMENT] llvm 3.7.1-2 On 10/06/2016 02:18, lloyd.w...@yahoo.co.uk wrote: > Thanks, picking up 3.7.1-2 from the mirrors.kernel.org site (as it's > not mirrored everywhere yet) resolved the 32-bit OpenGL crashing > issues with SaVi and Geomview that I reported in May; texturemapping > is back.

I guess this is the same 'piping problem' I asked for more details on back in [1]? Can you please provide more information?
