Hi, Vincent, If you could provide deb package for 10.04 Lucid (64 bit) with debug support -- that will be great! Probably my issue with ocl-icd build is due to old gcc? It is 4.4 I think...
If it requires 4.5, I think it's worth to check this condition in configure script... Well, it possible I waste my (and yours) time. How good is CPU code emitted with POCL? Will it use full 128/256/512 width of registers in instruction extensions? Of cause, my OpenCL kernel clearly states it wants to use uint4. Thank you in advance, Oleg.
