Hello,
I am having difficulty getting cg_annotate to perform line-by-line annotation.
I run cg_annotate as follows:
cg_annotate --auto=yes --include=PATH_TO_MY_SOURCE_TREE cachegrind.out.PID
PATH_OF_SOURCE_FILE_OF_INTEREST.c
The resulting annotation says that:
No information has been collected for PATH_OF_SOURCE_FILE_OF_INTEREST.c
When I look at the cachegrind.out file, there doesn't appear to be line number
information. I can't see how to tell valgrind I want to run cachegrind with
line number information. From the excerpt below, you can see that cachegrind
is able to fund function names, but not source file names:

I have compile my program with debug symbols, so I'm not sure what else to do
at this point.
Any suggestions would be appreciated.
Thanks in advance.
Brian
