controls.lpr(731,15) Error: Error while linking in laz4android3.4

[Bandy]

I get controls.lpr(731,15) Error: Error while linking in laz4android3.4 when trying to build a simple app that shows a simple message after installing laz4android and LAMW Version 0.8.6.4 with LAMW manager.

Please help!

Copy all messages and put them here, sometimes there is error above final error, which could shed some light on a problem.

How did you install LAMW? Did everything worked out without problems?
For what chipset are you building for?
Did you try to open some demoes that come with LAMW? Did you create regular form (you should use jForm)?
Check controls.lpr, what is around line 731.

Rename controls.lpr, as there is controls.pp unit in LCL.

EDIT: corrected typo control.pp -> controls.pp.

[dseligo]

Rename controls.lpr, as there is control.pp unit in LCL.

That's not the problem: 'controls' <> 'control'

[tetrastes]

Sorry, it's typo, the LCL unit is controls.pp.

[dseligo]

Sorry, it's typo, the LCL unit is controls.pp.

OK, but that still isn't a problem. LAMW doesn't use Lazarus' controls.

[tetrastes]

Then sorry for noise. I trusted too much to "write once, compile everywhere".

Hello,

The lamw install doesn´t use laz4android, look for lamw4windows on Start menu!
No, o LAMW  no use LCL.
My sugestion, is try create a new lamw project and report us .

We stay here to help you!

I installed LAMW with LAMW Manager. Everything worked out without problems.
Chipset is mt6853 on Samsung Galaxy A32 5G smartphone.
I didn't open some demoes that come with LAMW.
I opened a new project (LAMW [GUI] Android App]) and I used that form from the new project.
Around line 731 is:

begin
       gApp:= jApp.Create(nil);
730  gApp.Title:= 'LAMW GUI JNI Android Bridges Library';
731  gjAppName:= 'org.lamw.applamwproject1';
       gjClassName:= 'org/lamw/applamwproject1/Controls';
       gApp.AppName:=gjAppName;
       gApp.ClassName:=gjClassName;
       gApp.Initialize;
       gApp.CreateForm(TAndroidModule1, AndroidModule1);
end.

Well well... And what about not usung LCL..?

This could be something with the wrong path.
How are paths set in Project Options, Compiler Options, Paths (Other Unit Files and Libraries)?
Also check Custom Options in Project Options, Compiler Options (-FDC).
Check that paths actually exists.

Chipset is mt6853 on Samsung Galaxy A32 5G smartphone.
I didn't open some demoes that come with LAMW.

Try to open and compile some demoes that came with LAMW, to see if the problem is in your setup or in your app.
Also try to change Build Chipset (Project Options, [LAMW] Android Project Options, Build, Chipset). I usually build for Aarch64. Try to change this option for your test app and also for demo apps you try.

Do you actually use LAMW?

[tetrastes]

No, I don't, so I trust you that LAMW don't use LCL. But OP's project (due to dependency on laz4android) obviously does, which leads to duplicate units. Is that normal for LAMW project?
I'll install LAMW, out of curiosity.

[Thaddy]

It is not that difficult: LAMW does use the LCL but it DOES NOT use the default visual components.
You need the LAMW versions.

[nobody.00]

Hello, usually the lamw_manager install is enough and work very well
The error reported, is a missing library on linkage
Check your settings in menu -> Tools -> [LAMW] Android Module Wizard -> Paths Settings [JDK,SDK ,NDK,... ]


My sugestion, is use a lazarus building by LAMW Manager
