OpenCL: working with doubles error -


the error states: error: can't enable opencl extensions or unrecognized opencl extension
#pragma opencl extension cl_khr_fp64 : enable

system configuration:

  • windows 7 on 64 bit
  • notebook ati mobility radeon hd 5400 series
  • visual studio 2010

drivers installed:

  • amd-app-sdk-v2.8-windows-64
  • amd_catalyst_13.5_mobility_beta3

how can solve problem because need use double type in kernel? directive declared in first kernel line.

your gpu doesn't support double precision. why opencl runtime reporting cannot enable cl_khr_fp64 extension. if need double precision, try using cpu opencl device instead , run kernel on that.

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
