Check you options, target should be right. Recently I had a problem with the Compiler location option. It seems to be a option of the project ( which makes sense if you want different projects to behave differently ) not the ide installation, so especially if you got the project from someone else check it. For me a bad compiler location made the build take forever and do nothing; the compiler gave a useful error message. | Check you options, target should be right.
