I was looking for a tool that would generate a graphical call graph (aka
SGI's old Speedshop tools) but couldn't find anything appropriate in
'etch'. ie for a given Fortran code that has numerous subroutines I
wish to know what calls what (eg via gprof) but also to get a graphical
representation (without having to put it all manually into Xfig or the
like).

It's possible that my choice of apt-cache search strings meant I missed
something in which case pray tell!

The only thing that I could find with a quick Google was Intel's Vtune
but that seems inappropriate for Debian in that the provided install.sh
script attempts to find 'chkconfig', fails and aborts!

All ideas most welcome,
Ta, M

I'm not sure what the call graph output from gprof looks like, but you
might be able to script something to convert it to dot's format. See
the graphviz package. The format of the dot input file will look
something like:

digraph {
foo -> bar;
bar -> baz;
}

Doxygen will create small-scale call graphs for you, but it doesn't
work with Fortran.

For Fortran 77 I used to use the combination of ftnchek with switch -vcg
and vcg:

ftnchek, A static analyzer for Fortran 77
http://www.dsm.fordham.edu/~ftnchek/

VCG Overview
http://rw4.cs.uni-sb.de/~sander/html/gsvcg1.html

Would this work in your case?
