profiling Octave

[Jaroslav Hajek]

hi,

has anyone experience profiling with gcc/g++?
I wanted to try profiling Octave to identify hot spots in the
interpreter, but can't get it to work.
I configured using configure CFLAGS="-O2 -pg" CXXFLAGS="-O2 -pg"
LDFLAGS=-pg, then built and ran ./run-octave on a test script.
It produced a gmon.out file, but `gprof src/octave' does not show
anything. So far I was unable to find any useful information how to
get this working. A similar strategy works on a single sample C++ file
(g++ -pg, then gprof).
Has anyone experience with this? I would really prefer to do this with
GCC rather than a commercial compiler.

best regards
