c++ - CUDA: __device__ and __global__ error: expected constructor, destructor, or type conversion before "unsigned"/"void"" -


so problem is: i'm using nvidia's nsight application on mac os x mountain lion write cuda application: source code .h/.cu/.cpp mix.

i have hellocuda.h header following declarations:

//yep, both taken examples. __device__ unsigned int bitreverse2(unsigned int number);  __global__ void bitreverse(void *data);

and have hellocuda.cu file defines these methods:

__device__ unsigned int bitreverse3(unsigned int number) {     //definition     return number; }  __global__ void bitreverse4(void *data) {     //another definition...     bitreverse3(idata[threadidx.x]); }

it worked, until added new c++ class files (.h/.cpp) using eclipse's (nsight) new class wizard. now, when try build thing:

../src/hellocuda.h:21: error: expected constructor, destructor, or type conversion before ‘unsigned’ ../src/hellocuda.h:23: error: expected constructor, destructor, or type conversion before ‘void’

i checked project settings, don't think has changes.

so, gives? could, please, me one?

you created new cpp file using "cuda c bitreverse application" template. template cuda c file. delete file contents , add c++ code instead.

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
