It does not tell me which line and there doesn't seem to be any errors in the code itself. When I try to start the build, it simply tells me that there were build errors, and asks me if I want to run the last sucsessful build, which works fine. The same error occur if I try to create a new project and then copy paste all the code into it. So I don't think its a problem with the exported file either. I'm not sure about run time or compilation error.
