[ITP] VirtualGL 2.6.3

[ITP] VirtualGL 2.6.3

[DRC]

I intend to package the client for VirtualGL, a toolkit that adds
server-side GPU-accelerated OpenGL rendering capabilities to existing
remote X or X proxy environments.

VirtualGL is currently provided by various Linux distributions and FreeBSD:
https://pkgs.org/download/virtualgl
https://rpmfind.net/linux/rpm2html/search.php?query=VirtualGL

It is licensed under the wxWidgets Library License v3.1:
https://opensource.org/licenses/WXwindows

Archive containing proposed package files:

Re: [ITP] VirtualGL 2.6.3

On a Windows machine running Cygwin:

- Enable and start the cygserver service (needed in order to enable the
MIT-SHM extension in Cygwin/X.)
[https://cygwin.com/cygwin-ug-net/using-cygserver.html]
- Install (if necessary) and start the Cygwin/X server (/usr/bin/startxwin).
- Install (if necessary) OpenSSH.
- Launch XTerm using the X applications menu.
- /usr/bin/vglconnect -s {some-Linux-host}

NOTE:
As to whether the VirtualGL package should depend on Cygwin/X and
OpenSSH, technically the vglconnect script and vglclient application,
despite running in a Cygwin environment, could still be used with an
external X server and SSH implementation not provided by Cygwin.  Thus,
it's my opinion that the VirtualGL package should not depend on Cygwin/X
and the Cygwin-provided OpenSSH package.  However, I am open to being
convinced otherwise, particularly if there is an established precedent.

On the Linux host:

- Install the appropriate libjpeg-turbo official binary package,
depending on your flavor of Linux.
[https://sourceforge.net/projects/libjpeg-turbo/files/2.0.4]
- Install (if necessary) the X11 and OpenGL development kits (libX11,
libXext, libXtst, libGL, and libGLU.)
- Install (if necessary) CMake.
- wget
https://sourceforge.net/projects/virtualgl/files/2.6.3/VirtualGL-2.6.3.tar.gz
- tar xf VirtualGL-2.6.3.tar.gz
- cd VirtualGL-2.6.3
- mkdir build
- cd build
- cmake ..
- make vgltransut
- bin/vgltransut {some-BMP-or-PPM-file}

We don't make any other X clients depend on the X server, for the same 
reason, so this seems good to me.

Oh, please add a BUILD_REQUIRES line to the cygport.

Please provide a ssh key as per [1].

Am I good to go, or do I need to wait for Marco's feedback as well?

Done.

When can I expect to get SSH access in order to deploy my packages?

'Done' means it should be working now.

If it's not, you'll need to be a bit more explicit about the problem you 
are having.

Don't forget to first set up the remote host key with:

	$ sftp cygwin@cygwin.com

You can of course first use ssh-agent and ssh-add to preset your private key.

Using e.g.

	$ cygport virtualgl.cygport upload

is pretty foolproof and reliable if you set ~/.cygport.conf:

	SSH_KEY=~/.ssh/id_...

to your private key file.

For whatever reason, Jon's "Done" message did not reach me, so I
apologize for my confusion.  It works now.  Creating the ~/.cygport.conf
file was the missing piece of the puzzle.
