Sorry for not posting original post in correct format. However, after restarting the program after restarting the program I found out that the file obj\Debug\main.o doesn't seem to be created, created few projects with different options but some files are always not there. My antivirus doesn't seem to have prevented files from being created, and even after taking away permission to do so from it, new projects still didn't create those files. Old programs have all those files so I am not sure what is preventing creation of those files nor how to find it out.
