Hi Everyone,

I can't seem to get povray to build properly for profiling.  I've passed
CXXFLAGS=-pg LDFLAGS=-pg
to the configure script.  When I run povray, gmon.out is created, but when I run
gprof, i get this:

$ gprof ./unix/povray
gprof: file `./unix/povray' has no symbols

objdump -W ./unix/povray

does have a ton of output, so i think it does have symbols.


I'm using 3.7RC5

Has anyone had any luck with this?


Thanks,
Tom

you have to get ride of the -s in the compilation flag: try
--enable-debug on ./configure

or ...

Have you tried --enable-profile ? (nah, too simple)
