Hi
I was running the demo projects that cuda skd has.
And I was using the template one to learn how to use cuda
so far until today I was experimenting on it and everything was ok.
but today on all demo projects…they run well but if i try to change any of the files and run again, I get this stupid error.
and I have to cut and paste a fresh copy of the projects to be able to run them again but as soon as I modify any file… i get the same thing again
and i go the lines in which the errors suppose to be, but the kind of error does not even make sense…for intance it says something about a variable “exit” but that variable does not even exists in the template.cu file
sorry about my english
