As others have mentioned, you can write console programs with Lazarus, The
advice to use Lazarus is good advice, you can write both Console and GUI
applications with it.
As far as the .o file not found,
Try File > New > Project > Simple Program
You can put something simple like:
Writeln('Hello World');
Readln;
Between the Begin and End.
Then immediately try to compile it…
If you get an error about a .o file not found, then check your directories with
Tools > Options > FilesMaybe one of the directories is not in the right
place.
Or just try to re-install it.
Make sure to follow the installation instructions and pay close attention to
details, as I recall Lazarus needs to know where FPC is installed, you can’t
just run the setup program and click ok ok ok to everything until it’s done. I
think I had a similar problem with it once, and it was because it asked me to
set the path to FPC and I didn’t do it right or something.. and it was the kind
of thing that it only asked for once… either during install or the first time I
ran it, and if you don’t answer it accurately, nothing works right.
There are times you just don't want or need a program to do anything other than
sequential processing, and for those things Console applications are just
fine.. There is defiantly a place for Console Applications.
And there are times when having an event driven program is better.. it really
depends on the application. Personally I find that the easiest way to learn a
new programming language, is to have a desired task to perform and figure out
how to get it done.. The first step should be completing this sentence, ‘I
want to write a program to _’ . Once you have a goal,
then you can figure out how will the user interact with this program… when you
figure that out, you will know if you want a console application or a GUI
application. If the user doesn’t need to interact with the program a lot, say
you wan to just open a file and sort the contents and write out a sorted file,
then a Console Program is fine, and probably less complicated. If on the other
hand the user needs to constantly interact with the program, than a GUI program
is probably the best approach.
I primarily use the Free Pascal IDE. It's a little clunky for editing, so I
use Notepad ++ for editing, but then I always use the IDE for compiling. If I
have an error it is pretty clear what the error is and it highlights it for me,
and then I normally just fix it with the Free Pascal IDE. The reason I use the
FPC IDE is because I've tried several times to compile my largest projects with
Lazarus and they won't even compile there, and it seemed complicated to get
them to work... my projects have a lot of units, some units are {$mode TP}
others are {$mode FPC} I have very large portions of code that came straight
from Turbo Pascal, and I'm not sure why entire projects with all their units
compile with no problem with the FPC IDE and Lazarus produces error after
error. for code that works fine with the FPC IDE. Maybe I have settings in
the FPC IDE that makes everything work, that I don’t have in Lazarus. I’ve
tried a few times to get it to work but while Options > Compiler is easy to
find in the FPC IDE, I have no idea where the corresponding settings are in
Lazarus. I’ve tried looking under Tools > Options in Lazarus, and sure the
directories are there, but not compiler options. So now I have very involved
programs with close to a hundred thousand lines of code, that won’t compile on
Lazarus, so I keep using the FPC IDE.
There have ben occasions where I wanted to use a unit that was made for
Lazarus, but not FPC, and having this situations where I have huge projects
that won’t compile in Lazarus but work fine with the FPC IDE has required me to
work around using Lazarus units… unfortunately it’s been easier to do that than
to fix all the issues preventing me from compiling on Lazarus.
But… since you have zero lines of code… perhaps starting with Lazarus and just
write simple console applications with that would be the best advice, because
when your projects get larger and you decide maybe using some Lazarus units
might be a good idea, then you won’t have the compatibility issues that I have.

Re: [fpc-pascal] Hello, new Pascal programmer. had a question!
Although not likely in this case, I am visually impaired, use a screen reader, and find the Lazarius IDE nearly unusable. Of course, I've not touched it in years, because my first attempt at using it failed miserably, so for me, I simply use notpad, pico, nano, or text edit (depending on what platform I'm using), and simply compile from the command line for all of my pascal work. Possibly, the original poster is facing a similar challenge, and only wants to learn console programming, to keep things simpler. As already mentioned, OOP isn't really that simple to wrap your brain around, especially if you're a new programmer, and don't have the framework already built to understand how it all works. I'd honestly love to use an IDE for programming, as it would cut down on the amount of manual work required to get things done, but there are precious few that work well with screen readers, and so generally we're reduced to using text editors, and manual compiling. Nothing wrong with that method, it works, it just isn't as efficient as it might otherwise be. Powerbasic has a decent IDE, and I'll sometimes use that when powerbasic is required for a project, but I've gotten so used to command line and text editors, I rarely even bother with IDEs, even when I know they work. Powerbasic, FPC, java, python, gcc, and G++ are the languages I use most often, and I think I'd be hard pressed to find something I'd be comfortable with using all of them with a single IDE anyway, so I just don't bother.

It does, but it's not really addressing the core problem here. There certainly was an assumption in the Delphi era that you'd be building event-driven GUI apps.

I see where you are coming from, I think, but I can relate to the OP. I played with Pascal at university, and in my first job -- I wrote a Quicklife program and some fractal generators and things. TurboPascal was a good language, approachable and easy to understand. But Delphi was, to me, utterly impenetrable.

I'm just an amateur playing around and all the OOPS stuff blew my brain. I'm sure it's good and helpful for professionals, or even for skilled amateurs, but as a dabbler, it took a reasonably accessible language, far more readable than C, and made it overcomplicated and obscure and complex and basically just too damned hard for me.

Assuming that you have modern hardware that you do your programming on: Even if you only want to write console programs, using Lazarus as your IDE hase advantages over using the FP IDE. The Lazarus IDE comes with CodeTools which has code completion and much, much more features that you cannot do without once you're used to having them, even if you only use a few of them. I know: I came from D3 Pro, which at that time was a better compiler and a more stable IDE than Lazarus 0.9.something. But every time I came back to D3 (even just for testing something), I ended up trying to do Ctrl-Click on an identifier (to see it's definition: the IDE opens the source file at the position where it is declared), Ctrl+C on a variable in a new line of code, (just to declare it in the relevant var section) and of course that does not work. So, if you're on Windows, *nix or a Mac, my advice is to use Lazarus as your IDE of choice. -- Bart ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
Re: [fpc-pascal] Hello, new Pascal programmer. had a question!
Hi Joseph, Besides all other answers, once you have a (Turbo) Pascal basis you can read "Modern Object Pascal Introduction for Programmers" [https://castle-engine.io/modern_pascal_introduction.html]. It will show you old and new stuff.

Re: [fpc-pascal] Hello, new Pascal programmer. had a question!
I write almost all console programs with FreePascal and also use the Freepascal
IDE a lot.
It is compatible with Turbo Pascal and that is what I learned to program with …
because it was modern at the time So turbo pascal books are a good way to
learn Pascal in general, as I had no problem using advanced Free Pascal things
with a Turbo Pascal background… however I should point out that I am biased
toward Turbo Pascal because I have been using it since the mid 80’s, but Object
Pascal which is an extension of Pascal is quite a bit more popular and provides
Object oriented features like classes and methods… so while Turbo Pascal is a
good way to get started with general pascal syntax and understanding the
general way things work in Pascal, it would be a good idea to move into Object
Pascal and get familiar with that as well.
There is a tutorial here:
https://wiki.freepascal.org/Basic_Pascal_Introduction
The above tutorial has this link:
https://wiki.freepascal.org/Pascal_and_Lazarus_Books_and_Magazines
Which does have some links to books for Free Pascal without Lazarus
Free Pascal has some compiler options to make it compatible with various forms
of Pascal, one of them is Turbo Pascal, but if you compile the program with the
wrong one, you may ger unexpected errors. So if you want to use a Turbo
Pascal book, you should put {$Mode TP} at the top of your program to instruct
the compiler to compile it as a Turbo Pascal program. You can see the other
modes here:
https://www.freepascal.org/docs-html/user/userse33.html
If you do not specify a mode and did not change the default in the
configurations, I believe you will get {$Mode FPC}
As far as screen output goes, if you put Uses CRT at the top of your program
(under the {$Mode TP}) then you will be using the CRT unit, that handles the
screen much the way Turbo Pascal does.. but it didn’t need the unit because
that’s all there was… with that, you can use the ClrScr; command to clear the
screen first thing, then your program output is the only thing to see… When
using the IDE I also put something like a ReadLn; at the end of my program so I
can see the results before it switches back to the IDE.. Although pushing
ALT-F5 will also show you the output if you don’t have the ReadLn;
{$Mode TP}
Uses CRT;
Begin
ClrScr;
WriteLn('Hello World');
ReadLn;
End.

Subject: [fpc-pascal] Hello, new Pascal programmer. had a question!
Hello all,
I am a new programmer, and I thought I'd learn Pascal. I saw that with
FreePascal, most users are using Lazarus. I don't want to use this and would
rather work in the console, and use the free pascal IDE. I'm not really
interested in using any GUI tools. I was looking for a book that teaches free
pascal without the GUI stuff, that has a lot of examples in it, but i cannot
find anything of the sort. This has made me turn to Turbo Pascal books, and i
am currently reading "Learn Turbo Pascal in three days". When i use the free
pascal IDE to write code, and compile it, i have no issues. When i go to run my
program, any text i have printed, will mix in with the terminal/console text,
and doesn't just print at the bottom like i would expect. This has made me turn
to using emacs, and then just compiling the code in the terminal using "fpc
-Mtp ". My question is, id like to use the free pascal IDE, and
learn the more modern(?) form of pascal, but i cannot find a resource for
beginners that will teach me with a lot of examples, and not walls of text,
just for non-GUI applications. Does anyone know if such a book exists? Many
thanks!

That's how TP did it in days long past, so this is normal behaviour. The CRT unit allowed you to write on any part of the screen, so the output of the program was written in a separate screen.

The most recent book I know of was 'Learning to program using Lazarus', but as you see from the title, it uses lazarus.
