AN>Hi Herman,
AN> [...]
 HS>> If you ask me, djgpp is good at optimizing.
 NS>> Pretty good is right! Its also great for profiling. Sometime omit
 NS>> the -s and -fomit-frame-pointer switched, add in -pg (Assuming you
 NS>> have gprof which comes with DJGPP) and execute your program. This
 NS>> will kick out a dump to a file, then run gprof  |
 NS>> more or redirect output to a file, and you can see all kinds of
 NS>> stuff, how many times a function is executed, how long it took,
 NS>> etc, alot better then the big beastly confusing Turbo Profiler if
 NS>> you ask me.
 HS> It doesn't seem to work. When i try running "gprof tex.exe | more"
AN>it
 HS> returns with an error message "unrecognized file format".
AN>Have you run the Program once before (!!!) you tried the gprof ???
 HS> I tried running "gprof tex.o |more"  and it dumped a whole lot of
 HS> directives on the screen (as if i were to type gprof /? etc).
AN>No !! The o(bjekt)-file is the wrong parameter !!!
 HS> How do i get this to work?
AN>add "-pg" when compiling ... run the program ... start gprof !!!
I have, it just doesn't work.
I tried with the .o file and it dumps a file with crap results.
