Free Pascal Tutorial 15 - Starting Windows, Mac and Linux GUI Programming - Lazarus

[07bit]

@AlexsiMAC

The linux version of Lazarus will create linux executables. They will run on every linux without problems.

[07bit]

@TheCrazeBlazer

It is Pascal. What else did you think it is?

[Amzo2]

How do you enable it to prompt the code completion or to show available options.

In the video you type Label1.ca and it showed a list of options for it. It doesn't do this for me in Lazarus on Linux.

[smitthy100]

@anakin1337: Did you have "readln;" at the end of the program?

[smitthy100]

@alphacaprinus: Thats because of debuginfo. Go to compiler options and choose strip or something.

[PrankMaN97]

Сan I do the same with Turbo Pascal + DosBox + Win7 x64?

[alphacaprinus]

App1.exe is 11.4MB and the only thing it does is setting a label's text =(

[07bit]

@alphacaprinus

It contains debugging info. For release do the following: In the proect options:

enable "link smart"

disable "generate debugging symbols"

enable "strip executable"

this is absolutlly discasting OOP IN PASCAL nahhhhhhhhhh

[07bit]

@SAMY2690

there has been OOP in pascal since the 80's already.

[anakin1337]

im using lazarus on linux , and when i wrote writeln and readln thing, i wanna test the program, and when i press on that green play button nothing happens. PLease healp :)

[07bit]

@anakin1337

start it from the comand line.

Or uncheck the box "windows gui application" in the project options. Then it will be started along with a console window.

@AlexsiMAC i guess you need to use wine on that

[tsunamyboy69]

did you make a independet file for each operative system?

like exe for windows app for mac, and other for linux?

[nyah248]

My name ist Pascal^^

[DeRobyJ]

There are a lot of errors when compliling :(

I do all what you did, but it doesn't work!

The program opens a project1.lpr

Please help me!

[DeRobyJ]

@DeRobyJ Solved

{$IFDEF WINDOWS}{$R project1.rc}{$ENDIF}

This is after (you can add units after this).

I have to delete it also when I want to make a pascal program.

(I have 2.2.4 compiler, yours is 2.2.2)

[MrDimwit646]

dosent work :(

[Gage5137]

where do you get this program?

[Gage5137]

where do you get this program?

[SchoolFreeware]

@Gage5137 Free Pascal's Website. Free Pascal is the programming language. Lazarus is the IDE. Code in this tutorial is found at SchoolFreeware's Website

[Ceniza666]

@besnsch89 Just call Form2.Show or Form2.ShowModal in the OnClick event of the button.

ShowModal will disable the current form until it is closed. Show will let you have both forms active at the same time.

Hi kokoinas, i've same error.

I don`t know is the problem, i'm now using windows 7 and lazarus 0.9.28.2.

[SchoolFreeware]

Hello There is documentation on Google about this

Google This (with the quotes): "New User - Compiling Problem"

You may need to save the code first then compile (run) or possibly install the newer version of Lazarus. Supposedly this bug has been fixed.

[kokoinas]

well, something is wrong to my coding:
