Xcode gcc: dependency_info.dat No such file or directory

Hi anyone can help with dependency_info.dat No such file or directory? I'm using Xcode 7 with gcc 4.8

-dependency_info /path/my_project/build/my_project/Debug/my_project.build/Objects-normal/x86_64/my_project_dependency_info.dat

g++-4.8: error:/path/my_project/build/my_project/Debug/my_project.build/Objects-normal/x86_64/my_project_dependency_info.dat: No such file or directory
Command /usr/local/bin/g++-4.8 failed with exit code 1

what does -dependency_info flag do? How can I remove this flag?
