Cuda opengl interop and cudaGraphicsGLRegisterImage causes error -

i trying cross card communication cuda running on k20 , opengl running on quadro seem unable register texture want use cuda.

my code looks this

glgentextures(1, &texid); glbindtexture(gl_texture_2d, texid); glteximage2d(gl_texture_2d, 0, gl_rgba, texturesize, texturesize, 0, gl_rgba, gl_unsigned_byte, 0);  glbindtexture(gl_texture_2d, 0);  checkglerror();  // passes    // cause access violation when run visual studio 10 debugger  cudagraphicsglregisterimage(&texres, texid, gl_texture_2d,cudagraphicsregisterflagsnone);  // if ran out debugger, cudageterrorstring() spit out "invalid argument" checkcudaerror(); 

cudagraphicsglregisterimage causes access violation when run visual studio 10 debugger

but...

if ran out debugger, cudageterrorstring() spit out "invalid argument"

i not sure problem , made more confusing different error messages.

well seem have figured out wrong changed line...

glteximage2d(gl_texture_2d, 0, gl_rgba, texturesize, texturesize, 0, gl_rgba, gl_unsigned_byte, 0);  

to...

glteximage2d (gl_texture_2d, 0, gl_rgba8, texturesize, texturesize, 0, gl_rgba, gl_unsigned_byte, 0); 

i not sure why cuda has problem gl_rgba seems case.
