Call-graph data in profile output

[ereisch]

I'm trying to perform some statistical analysis of my Fortran program using gprof.  When I compile my files with "-p", the expected gmon.out file is created, however the profile file lacks call-graph data:

$ gprof -c -z -q myprog
gprof: gmon.out file is missing call-graph data

Is there a compiler flag I'm missing, or does the compiler not generate this information?  Version 12.0.4.191 Build 20110427

Thanks

 Are you running your application after you compile your application. That will generate the gmon.out file.

Yes, the gmon.out file is being generated.  The post was that the call-graph data that gcc and other compilers tend to place in the gmon.out file is not being populated by the ifort compiler.

What version of gprof are you using? and does this happen with every program or just one? 

I am able to get call graph data using that version of the compiler and GNU gprof version 2.20.51.0.2-5.28

Hmm.....that's interesting.  When I generate a small program and compile/link it, I get the expected behavior.  But when I run a larger, more complex program, I don't get it.  I'll continue to try to narrow down to get a reproducer.

Any luck with reproducing this issue ?
