Build problem on Windows with Alire

[frankltr]

Hello,
this is the issue description:

OS:
Windows 10 Pro Version 10.0.19045 Build 19045

Software Version:
Gnatstudio 25.0w: gnatstudio-25.0w-20240506-x86_64-windows64-bin.exe
Alire 2.1.0: alr-2.1.0-installer-x86_64-windows.exe
MSYS2 environment: MINGW64_NT-10.0-19045 version 3.5.7-2644508f.x86_64 (runneradmin@fv-az833-983) (gcc version 13.3.0 (GCC) ) 2025-03-11 08:33 UTC

Steps to replicate problem (from scratch installation):
On the powershell alire prompt:

PS C:\projects\ada> alr init --bin first
PS C:\projects\ada>cd first
PS C:\projects\ada\first> alr with gwindows

....
Note: Deploying gprbuild=22.0.1...
################################################################################################################# 100.0%
Note: gprbuild=22.0.1 installed successfully.
Note: Deploying gnat_native=14.2.1...
################################################################################################################# 100.0%
Note: gnat_native=14.2.1 installed successfully.
Requested changes:

• gwindows ^1.4.3 (add)

Changes to dependency solution:

• gwindows 1.4.3 (new)

Do you want to proceed?
[Y] Yes [N] No (default is Yes) y
Note: Deploying gwindows=1.4.3...
################################################################################################################# 100.0%
Note: installed successfully.

After that still on the alire prompt:
PS C:\projects\ada\first>alr edit

On GNAT Studio try to build first.adb (default starting code):

procedure First is
begin
   null;
end First;

with first.gpr:

with "config/first_config.gpr";
project First is

   for Source_Dirs use ("src/", "config/");
   for Object_Dir use "obj/" & First_Config.Build_Profile;
   for Create_Missing_Dirs use "True";
   for Exec_Dir use "bin";
   for Main use ("first.adb");

   package Compiler is
      for Default_Switches ("Ada") use First_Config.Ada_Compiler_Switches;
   end Compiler;

   package Binder is
      for Switches ("Ada") use ("-Es"); --  Symbolic traceback
   end Binder;

   package Install is
      for Artifacts (".") use ("share");
   end Install;

end First;

and with config/first_config.gpr:

Note:
The problem is not only with Gwindows package, but also with gtkada and others i've tried.
Building on powershell command prompt in alire work with: alr build
Tryng to install GNAT studio as administrator for all user(administrator) and for single user to evaluate possibile path environment conflicts, but no change.
With only toolchains installed GNAT Studio work without problem.

Thanks and regards,
Frank
