visual studio 2008 - CUDA not working in 64 bit windows 7 -
i have cuda toolkit 4.0 installed in 64 bit windows 7. try building cuda code,
#include<iostream> #include"cuda_runtime.h" #include"cuda.h" __global__ void kernel(){ } int main(){ kernel<<<1,1>>>(); int c = 0; cudagetdevicecount(&c); cudadeviceprop prop; cudagetdeviceproperties(&prop, 0); std::cout<<"the name is"<<prop.name; std::cout<<"hello world!"<<c<<std::endl; system("pause"); return 0; } but operation fails. below build log:

i highly obliged if me. thanks
add cudart.lib additional libraries. see here more info.
to add library, go to
project properties / configuration properties / linker / input / additional dependencies
and add cudart.lib
update: cuda default install native binaries. you're on 64bit system. if must compile 32bit application, need download , install 32bit cuda toolkit 32bit binaries -- thought including them default, i'm away win7 box right -- i'll check later & update.
the other option, which recommend, switch building native, 64bit binaries. so, you'll need edit configuration management , switch win32 x64.
if don't have x64 option, you'll need go third configuration management option , add profile x64.
the basic point since you're trying link 32 bit app, ignores 64bit binaries have installed.
