Fatal: (10022) Can't find unit Laz_AVL_Tree used by ComponentReg

[daniel_sap]

Hi,
Decided to upgrade my Lazarus 3.6 installation to 4.0RC1 (on Windows 11 64 bit).
The download and installation was successful.
After the installation I tried to Build Lazarus with Profile: Normal IDE which gave an error:
Fatal: (10022) Can't find unit Laz_AVL_Tree used by ComponentReg

Code: Pascal  [Select][+][-]

I see that there are lot of 'Note: Duplicate unit'
Can you direct me how to approach such an issue. thanks

Have you tried a "clean" rebuild ?

Have you tried a "clean" rebuild ?

Yes, one of the first things I tried was to clean rebuild.
The log I provided is the build after the clean.
Before the clean may be the error was different - componentreg.pas was not found because the ppu is Incompatible
and it showed the error windows that there are 2 files with the name componentreg.pas

Looks like you mixed the sources of old and new lazarus.
I'ld just entirely remove the c:\Lazarus2 folder and then re-install Lazarus.

I did a clean installation and it works fine.
I wanted to do the upgrade to save myself the installation of a hundred packages (as far as I know there is no way to do multiple package installation from outside the IDE, from some script file for example)

[emersonline]

Looks like laz_avl_tree.pp has been removed from "[lazarus installed directory]\components\lazutils" for 4.0RC1 release. There is a note from Mattias Gaertner inside laz_avl_tree.pp about this:

Note! This is a copy of avl_tree unit from FPC trunk from Apr 2023.
        Can be removed when FPC 3.2 is the minimun requirement for Lazarus and LazUtils.

In that case, in order to compile using 4.0RC1, replace "laz_avl_tree" for "avl_tree" from the Uses sections of your units.
