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)
