[SOLVED] Command line application
lazarus / 32-Linux

Hi all,

I am currently using FPC 3.0.0 and Lazarus 1.6.0 under Ubuntu 15.04.

What I would like to do is develop a small command line application
which should do some measurements based on command line parameters. As
I have never done this before, and being unsure about required
settings in Lazarus and what parts of the RTL I would need to include
I wanted to ask for some guidance.

So question is - what do I have to consider to get this going - would
someone care to help me out with a small skeleton if available.

Kind regards,
MathMan

File -> New -> Console application

I would suggest File -> New -> Program instead. Console application is
a bit too complex for a start although you have all the benefits of
TCustomApplication.

Thanks mig-31 and Leledumbo - I'll give it a try this way and see how
far I get.

In case you are in need of some help with the command line options,
please have a look at unit GetOpts, examples are present in
documentation.

You could of course always use the ParamStr and ParamCount routines as
well.

Depends a little on how complicated things are going to get.

mig-31, Leledumbo, molly,

It was a busy night yesterday but I got it running. Used the approach
suggested by mig-31 to go for "Console Application" as I got all the
command line handling utilities (like HasOption, GetOptionValue, etc.)
for free.

Background was that I had increasing doubts about the benchmark
measurements I got when I used the benchmarking tool that I integrated
into my GUI application. Now I have a replication but as a command
line tool - lo and behold there are differences between measuring from
inside a GUI app to measuring from a console app inside a shell!

There are still some small things to do, as I want to follow this
http://www.intel.com/content/dam/www/public/us/en/documents/white-
papers/ia-32-ia-64-benchmark-code-execution-paper.pdf as close as
possible without restorting to kernel mode drivers.

Anyway consider the issue solved.

Regards,
MathMan
