Re: FOX 1.7.78 OpenGL not working?

I’m not entirely sure if this is pertinent but…

 

I’m wrote a Fox app (v1.7.50) using several OpenGL 3D drawing calls from within Fox. I’m running ubuntu in a VMWare virtual machine on Windows 10.

I have used VMWare (VM Player) and have had trouble with 3D applications, such as Altium (PCB layout software) - getting the same "black window" as you see.  This was the Linux-hosted version of VMplayer, running a Windows 7 VM.  I don't use VMplayer under native Windows, but I would imagine it has the same problems accessing the graphics hardware.

 

I would not blame FOX for any 3D problems in that environment.

 

Not really relevant to you as a Windows user, but I have had more success using Wine (Wine Is Not an Emulator) to run windows 3D applications under Linux, than trying to use a VM.

Understand.  I am not complaining about that  :-)

- Just trying to figure out - why with the same VM environment, gltest 
was working with Fox version 1.6.57.  Now it stops working with Fox 
version 1.7.78 for the same VM.
- I use VM for development/testing my SUMO project. And with version 
1.7.78 SUMO won't work inside the VM environment at all.
- I need to mention - on a NON-vm environment, i.e., a physical 
computer,  gltest build with Fox v1.7.78 works just fine.

Any insights or hints would be appreciated.

Thanks again
Wuping
