FMXLinux + Windows Subsystem 4 Linux + GWSL

[Chris W]

Hello,

I’m trying to une FMXlinux 1.69 with Delphi 11.1 and make it run on a WSL ubuntu 20.04 machine from windows store

and and XServer GWSL also from windows store.

In fact ./paserver is running and it works well, except … when I right click on a memo or Tedit

then I get a “range check error”

‌

is the error is related to Delphi / Fmxlinux / ubuntu/ or GWSL XServer ?

‌

Not sure but “Range check error” message looks very familiar to me as a delphi coder.

‌

But also, if I compile in release mode with range checking OFF the nature of the error changes and I get a

“Cannot create render buffers for ‘TContextOpenGL’

‌

Did I run in a limitation of the GWSL experimental XServer ? What’s your guess ?

‌

Have a nice day

Thank you

‌

PS: WSL is cool … a linux machine up and running takes only two clicks

Right clic sould display a default popupmenu.

Debugger shows it enters procedure TContextOpenGL.DoInitializeTexture(const Texture: TTexture);

and the crash occurs on line glBindTexture(GL_TEXTURE_2D, Tex);

I’m stuck there

Slow progress

If I change inside TContextOpenGL.DoInitializeTexture

var Tex: THandle; to var Tex: GLuint;

And in TContextOpenGL.DoCreateBuffer

var LTexture: Integer; to LTexture: GLuint;

I can get rid of the range error

‌

But the final Error “Cannot create render buffers for TContextOpenGL” remains in TContextOpenGL.DoCreateBuffer

where Status <> GL_FRAMEBUFFER_COMPLETE_EXT (status value is 0) in the second ELSE part without Multisample

‌

And I guess this is where my pascal capabilities end and I start needing an opengl expert please

Hmm I wonder … glxinfo | grep "OpenGL version"
OpenGL version string: 1.4 (4.6.0 NVIDIA 388.13)

Is this correct ?
