Missing conditional windows compiling switches.
lazarus / 6-IDE-CodeTools

----------------------------------------------------------------------
KodeZwerg · 2022-11-24 18:05

Since my thread over here https://forum.lazarus.freepascal.org/index.p
hp?topic=61335.msg461190#msg461190 was not successful I would have a
suggestion to make for upcoming releases of Lazarus IDE.
Please do add in the .lpr file a proper way for Windows based
applications.

A console application need {$APPTYPE CONSOLE} (and a GUI application
can have {$APPTYPE GUI})
Of course it shall have checks like {$IFDEF MSWINDOWS} etc....

Thanks in advance!

Please help friend. 
Since we are in the suggestions forum, there is no need for you to

I apology for my rude answer, without that conditional switch a
console application will having a bad end. I hope that is answer
enough.

You can set it in compiler options.
Uncheck Win32 GUI application in "Config and Target".

It does not add the needed line, on image i show options, i confirmed
them, re-opened options to make snapshot.

Ahhh but it stop getting me the error 103 message and keeps console
up.
Why does that config not getting applied when I select "simple
application" from "Create new project"

The $apptype directive is not only for Windows. And the compiler will
only warn about it on platforms that don't support it. So I don't
really see a use for this.

IIRC Delphi7 dislikes ifdef's around {$apptype} directive.

Not sure.
In the not so long past I did a feature request for a "default
compiler setting" per project type.
That would solve this problem.
Unfortunately I have no idea how to implement something like this
myself, the IDE is way to complex for me.

Why do you think so? From https://www.freepascal.org/docs-
html/current/prog/progsu86.html#x94-930001.3.3
QuoteCONSOLE
A console application. A terminal will be created and standard input,
output and standard error file descriptors will be initialized. In
Windows, a terminal window will be created. This is the default.
When creating project for GUI (Application) Lazarus simply adds -WG
(Win32 GUI application) option to project options.
So there is no need in {$APPTYPE ...}.

What do you mean? Lazarus doesn't add -WG when creating projects for
console programs.

The default compiler setting on Windows is to have -WG set for all
project types.
(I.o.w. the "Win32 GUI application" checkbox is checked by default in
Co,piler Options->Config and Target)

When I not deactivate that -WG switch or when I do not have {$APPTYPE
CONSOLE} in the .lpr file,
the attachment show what happen on a Windows machine, that is the
reason of why I would like to have such per default set.

No, unless you check "Set compiler options as default" when "Win32 GUI
application" is checked (and press "OK" button, of course).
Moreover, if you do this when "Win32 GUI application" is unchecked,
projects for GUI Applications will be created without -WG.
At least this is so at my Lazarus 2.2.4.
You can verify this by looking in Lazarus config folder
(C:\Users\...\AppData\Local\Lazarus by default) for file
projectoptions.xml. If it is there, delete it, and see how different
projects are created.

In my thinking I more like to get a warning instead of no console
appear at all when you not uncheck -WG or having the conditional
active.
But okay (since you helped me on my other thread to fix that issue on
my own I can live with it even if I am unsure if that be the correct
behave of an IDE that should support the user)

That may very well be the case, since I saved and use default compiler
options (with debug and release versions).
