I'm a new user of Lazarus.
My OS is UBuntu 10.04
installed Lazarus: IDE v0.9.28.2

In the past I made some applications for Microsoft Windows with
Delphi.
After compiling you get a exe file. And then you can run it.

Now for Linux.
Making a commandline program for Linux.
A program that say's "HELLO" on the terminal window.
(verry small program)

Where can I find the configuration settings of the compiler to make a
linux appl.
And some explanations of the inputs and outputs.
What do I have to do after compiling : installing ? How ?

Thanks for your time to help me.

If your project is project1.lpi
then to run it you have to type this in the terminal:
Code: [Select]./project1
and press return

the "./" tells the terminal to execute that program. I don't know why
we have to do that it didn't happened in slackware 11 ....

In the Lazarus IDE choose:
Project -> New Project -> Program
This is a commandline program.
Then it will compile inside the Lazarus IDE.
If you are interested in how the command line params look.
See Project -> Project Options -> Show Options Button
Might look like:
 -MObjFPC -Scghi -O1 -gl -vewnhi -l -Filib/i386-linux/ -Fu.
-FUlib/i386-linux/ -oproject1

Maybe in SW 11 the current directory "." was added to each users
search path by default.

Thanks for all.

The option ./ helps a lot. It starts the programm.
Why is that programm 800KB large ? Just for 1 text output line.

You may have a binary with debug symbols not stripped. See also:
