Not able to generate .dyn file

Not able to generate .dyn file

I am working on code-coverage Analysis of my C++ Application. For that i am facing issue of ".dyn" (.dyn file is not generated). Below are the steps that I have followed

1.> I am compiling my application with makefile. I used "-prof-genx" option along with other existing options in my makefile and file pgopti.spi & pgopti.spl (size = 0) generated.

2.> Now I am running my Application, but ".dyn" file is not generated (It is suppose to generate after running the application)

Since lack of .dyn file I am not able to moov further. Please help me.

Thanks
