If you are referncing another lib in a project and you goto build and get
fatal error LNK1104: cannot open file ‘C:MyProjectDebug.obj’
Do a double check in the project you are referencing configuration. If you have a space in the name (Say “Debug Test”) you might see this error and scratch your head. If the project you are referencing outputs to $(ConfigurationName), then the output directory will have a space. Seems that when you reference that project or lib, it doesn’t like it with a space in the path name, doh! 🙂
