My Environment ：
windows 11
Lazarus 3.0 (rev f771d54e) FPC 3.2.2 x86_64-win64-win32/win64
LAMW 0.8.6.4
JDK-21
apache-ant-1.10.14
gradle-8.6
android-ndk-r27c-windows
Android SDK Platform-Tools 35.0.2
Android SDK Build-Tools 36-rc3
Android 14.0 ("UpsideDownCake")

Question 7
   a) As shown in the figure below, if I change any other Chipset
except ARMv7a+VFPv3, it will give me an error.
   b) How can I solve this problem

It's a continuous and connected problem
1、Compilation error

2、Invalid library address

6、arm-linux-androideabi-as.exe not found

7. Change Chipset failed

I feel lamw is like an aircraft carrier, powerful, but a bit leaky for
a newbie, and there are a bit many leaks.
Please give me guidance from the gods as well, thank you very much!

The code for this question is here, know if I'm guessing right. It may
be this code that is causing me this problem

procedure TFormSettingsPaths.ComboBoxPrebuildChange(Sender: TObject);
var
 pathToNdkToolchains49: string;
 saveContent: string;
begin
  if EditPathToAndroidNDK.Text = '' then
  begin
    ShowMessage('Please, Enter "Path To Android NDK..."');
    Exit;
  end;

  saveContent:= FPrebuildOSYS;

  pathToNdkToolchains49:= EditPathToAndroidNDK.Text+DirectorySeparator
+'toolchains'+DirectorySeparator+
                                                'arm-linux-
androideabi-4.9'+DirectorySeparator+
                                               
'prebuilt'+DirectorySeparator;

  if not DirectoryExists(pathToNdkToolchains49 +
ComboBoxPrebuild.Text) then
  begin
     ShowMessage('Sorry... Path To Ndk Toolchains "'+
ComboBoxPrebuild.Text + '" Not Found!');
     ComboBoxPrebuild.Text:= saveContent;
  end
  else
     Self.FPrebuildOSYS:= ComboBoxPrebuild.Text;

end;

Lower your NDK ex:22, on higher ndk your need to copy some build tools
from lower NDK, i dont remember exactly, like llvm was throw away on
higher NDK, build on android studio, all your problems instantly gone.

Thank you very much for your help, I have solved it a few days ago and
rewrote a posting to make it easier for people who come after me to
use lamw. but at the moment I have a new problem with debugging, such
as adding breakpoints, and how to debug it which I don't quite
understand yet. If you know it and would like to share it, I would be
very grateful and will rewrite a debugging post to make it easier for
later people to get started!
