I made the download and it looks to me that the closest thing to an
executable is several batch files. Can you discuss how to use it on a
rudimentray C program?

Did you read the readme.txt file that was contained in the archive?

I guess this is a problem with either your platform or the way you
are using it. Maybe the way you launched the script caused you to
fail to see its output.

Not when I posted, but I have now. When I run test_demo.bat, I have a dos
window open up, do something for about a half-second then close. I don't
feel like I'm a whole lot closer to using it on a toy C program except for
the reading.

There is a Makefile in the src directory, and it works for me (on a Mac),
but there does not seem to be a compile.bat file as mentioned in
readme.txt. The run_demo.bat file surely won't do anything interesting
if you haven't compiled yet. Have you tried doing a "make"?

That makes it sound like there's a compiler there, but is it the point that
I have to bring my own, as well as my own source? Then I could have as a
line in a batch file something like:
echo on
gcc some_file.c
pause

Hi Wade,

I am ready to answer your questions.

By the way, perhaps, is it worth continuing the discussion in special Google-group related to C/C++ Program Perfometer?:
comp.lang.c++.perfometer
http://groups.google.com/group/perfo?hl=en

See also
programming.lang.c++.sources
http://groups.google.com/group/sources?lnk=rga&hl=en

Do you run it from the command prompt? If not, open a DOS window first
(start button, "run", enter "cmd.exe"

I set the follow-up to
comp.lang.c++.perfometer.

.... is the world getting smaller?

I wanted to time a rudimentary C program because there was a contest
outstanding in c.l.p.misc, and I thought I could gerrymander the result.
I've got less than a half hour to beat the time, so I'll talk to you soon.

Gruß,

Er, no, open source packages never include compilers, unless a compiler
is the actual product (as with gcc). When you buy a box of cereal, do
you expect to find a bowl, a spoon, and a carton of milk inside the
package?
