source viewing problem with Vtune GUI

I am only able to view assembly in the Vtune GUI. I see the assembly but the "Source" button is grayed out and not active.  I compile with 

-g -O3 -fp-model fast -xMIC-AVX512 -qopt-report=5 -dynamic --vtune

I run with

 amplxe-cl -no-auto-finalize -collect hotspots -r res_dir 

I finalize with 

amplxe-cl -finalize -search-dir /global/u2/m/madams/petsc/arch-knl-opt64-ma64-simd/lib/ -source-search-dir /global/u2/m/madams/petsc/src/dm/impls/picell -source-search-dir . -search-dir . -source-search-dir /global/u2/m/madams/petsc/src/dm/dt/interface

The function that I want to view is in a c file in this ...dm/dt/interface directory.
