Re: [Public WebGL] Could not initialise shaders in Chromium



Should that be --use-gl=desktop? If seems rather inconsistent to have --enable-webgl and -use-gl. For long option names -- is supposed to be the standard.

Chrome silently ignores obviously crap options (e.g. --crap) and there seems no way to get it to print a list of valid options. --help and -h are ignored too. Chrome just starts up in all of these cases.

I'd like to make sure I'm using OpenGL not Angle/D3D.

Which version of Chromium?

I'm using the Canary Build of Chrome (on Win7)
http://tools.google.com/dlpage/chromesxs
As of day version 7.0.514.0

with these options
--enable-webgl -use-gl=desktop

And both links work for me.

Hi,
got some errors when opening a webgl-page like
http://learningwebgl.com/lessons/lesson03/index.html in Chromium
7.0.507.0 (57653): "could not initialise shaders".
for example on http://www.ibiblio.org/e-notes/webgl/ethanol.html i
just see a blue canvas.

Then another issue with firefox. But in this case it is obviously my fault:

ERROR: 0:42: 'assign' :  cannot convert from 'const mediump int' to
'varying mediump 3-component vector of float'
ERROR: 1 compilation errors.  No code generated.

and then the second alert: "could not initialise shaders".

After refreshing the site no errors occur and everything works fine in Firefox.


You know why?
