Hey, I'm trying out some of the shader samples on the forums, and they just won't run on the latest build, giving out the error "cannot create canvas: not supported by your opengl implementation". They however work on an earlier build.
Attached are pics from 6.sept build and 11.oct build respectively - running caleidoscope-fixed.love by kraftman
My computer's an Acer Aspire Timeline 3810T with integrated Intel graphics.
PO2; It's not my program, and it worked in a previous build..
The newest build - october. 14 - gives me the error "attempt to call field 'newPixelEffect' (a nil value)", still using caleidoscope-fixed.love from the thread at http://love2d.org/forums/viewtopic.php?f=4&t=3733
You actually grabbed a build of the 'minor' branch, which hasn't been updated in a bit, the builds of the 'default' branch failed today, but this should have been remedied, and it should all go well tomorrow.
I tried installing the latest Mobile Intel® 4 Series Express Chipset Family drivers, but it wouldn't let me, saying a customized computer manufacturer driver is installed on my computer (Acer; latest Acer driver installed).
Could well be the reason for my problem, though I still find it weird the earlier build worked..
Stencils were added in the time you mentioned, and the canvas code was changed in order for stencils to work with them. So that's likely the cause of the problem. Strange thing though: The Intel GMA 4500MHD (the graphic chip in your laptop) should be able to work with the changed code.
To be sure though, can you look if the driver supports the packed depth stencil extension: GL_EXT_packed_depth_stencil?
On Windows, you can get a list of extensions supported by your driver using the GPU Caps Viewer or GLview. On linux, you can use the command glxinfo | grep GL_EXT_packed_depth_stencil.

I have come here to chew bubblegum and kick ass... and I'm all out of bubblegum.
