I have an OpenCL program written in C and in the same directory I have OpenCL.dll and its relative .lib and .exp named OpenCL32.lib and OpenCL32.exp which I've exported from OpenCL.dll.
I use the following compile command
cl.exe /Zi /EHsc /nologo /IC:\Users\marco\Desktop\OpenCL-Headers /Fe: main.exe *.c /link OpenCL32.lib
and I get this error
main.obj : error LNK2019: riferimento al simbolo esterno _clGetPlatformIDs@12 non risolto nella funzione _get_GPU_platform

Any suggestion? Thanks.
Follow the steps described here. You have to tell Visual Studio the location of
OpenCL.libin the project settings for linking.
