I’m trying to run an SDL program inside a VM. I ran my SDL driver test app, which uses the following code to enumerate renderers available:
for i := 1 to SDL_GetNumRenderDrivers do
begin
SDL_GetRenderDriverInfo(i, driverInfo);
radDriverList.Items.Add(driverInfo.name);
end;
radDriverList is a radio button group box. It ends up with the following choices:
gdi, opengl, software, software
When I click on the OpenGL one to examine its available render modes, I see Single Buffer, Flip 3, VSync and Accel. So SDL is reporting that I have an OpenGL driver available that should be able to handle triple-buffering.
Then when I go to create an SDL window, using the OpenGL flag, it creates successfully, but when I try to create a renderer for it with the triple-buffer flag, I get -1. A call to SDL_GetError returns “CreateDevice(): NOTAVAILABLE”
Anyone know what’s going on here?
I’m not sure what is wrong, but a bit more information would be helpful.
Host OS, VM type and Guest OS, to start with.

No idea. Though I just found out that trying to create a renderer for a window created without the OpenGL flag results in the exact same error, so it doesn’t seem to be an OpenGL issue specifically.

SDL may be using OpenGL by default if you’re using 1.3.
Decent 3D graphics support is pretty rare in virtual machines. You
might want to try VirtualBox since they have OpenGL (no DirectX
though).
