I've run and collected the cpu and heap profiles of my program. When I
try to interepret the CPU profile through pprof, I get a message "No
node to print". I have let the program run for about 30 minutes and the
profile file is not of size 0. (It is about 3k). What does this mean?

Usually it means the program hasn't finished properly.  Is it possible
your program is hanging for some reason?  Or it was killed by
interrupting it instead of a clean exit?

One thing to try is to run pprof without the --gv option and see what
if any errors get printed.

Also, run "strings <profile>" and see what is printed.  In particular,
does a /proc/pid/map copy come out?

No, the program is finishing properly.

When run without the --gv, it prints nothing

The entries in /proc/<pid>/map  and <profile> are similar but not the
same. I mean, the .so's listed match but not the addresses..

I'm having the same issue...
Most of our work takes place in shared libraries .. maybe this is the
problem.
I haven't had much success getting any profilers to work with shared
libraries oprofile seems to be the best bet.
