Compilation issues with gl_VertexID name

[sthibaul]

Hello,

When running DepixelizeOnGPU, I am getting

Compiling shader : ../shaders/Optimization/OptimizeEnergy.vert
0:54(8): error: `gl_VertexID' redeclared

Linking program
error: linking with uncompiled/unspecialized shader
Compiling shader : ../shaders/UpdateCorrectedPositions/UpdateCorrectedPositions.vert
0:24(8): error: `gl_VertexID' redeclared

Just for trying, I renamed them into gl_VertexID2, and got instead

Compiling shader : ../shaders/Optimization/OptimizeEnergy.vert
0:54(1): error: identifier `gl_VertexID2' uses reserved `gl_' prefix

Linking program
error: linking with uncompiled/unspecialized shader
Compiling shader : ../shaders/UpdateCorrectedPositions/UpdateCorrectedPositions.vert
0:24(1): error: identifier `gl_VertexID2' uses reserved `gl_' prefix

I don't know if this is supposed to have exactly this name, otherwise I guess it should be renamed to avoid being in the gl_ namespace?

(renaming to VertexID gets these three errors away)

gl_VertexID gets decalred implicitly. I think the only change is to comment these lines:
in input gl_VertexID.

@sthibaul By the way, have you been able to successfully compile this code? I can compile on windows with NVIDIA Titan, however, the graph extractions does not seem to work.

I have the same problem ! I run it on Windows with NVIDIA GPU .
here is the result :

Hello. I am encountering the same issue on windows with Nvidia GPU as the above comment. Could anyone figure out how to fix this issue? @sthibaul @falichs

SImilar here. Managed to compile and run, cleared the gl_ related stuff, that's the output I get from F2-F4:

Doesn't seem to be the hardware, as I've ran demo linked here and I get:

There are some glitches in the b-spline image, but honestly I don't really care, I'm after Voronoi here.

It looks a bit like it fails on building a similarity graph in what I compile. The graph is there, but not connected, like in the second pic. So then Voronoi is all-square, and b-splines are a mess...

Any ideas? @falichs @sthibaul

Hi Everyone!
Sorry for my late response - i did not find the time to maintain this very old student project ;)
i just pushed a commit, which should fix at least some of your issues!
