Undeclared identifier @varclr

Hi.

In Delphi 10.4, I get this error: Undeclared identifier system.@varclr
The error happens on line 39972 of syncommpons.pas (dated 12/27/2019) , and is called on line 895 of Sqlite2pages.pas (dated 02/2920)..
Is there any fix for this, or maybe am I doing something wrong?
Everything worked fine in Delphi 10.2. It broke with 10.4.
Thanks for your help

Re: Undeclared identifier @varclr

Did you try a more recent version from https://github.com/synopse/SynPDF or https://github.com/synopse/mORMot ?

I can't reproduce the problem here.

Thanks.
Yes I did try the newer versions. However I see these lines in syncommons.pas
{$ifdef LVCL}
        dd      @@err
{$else} dd      System.@VarClr
{$endif LVCL}
What is LVCL and where is it defined? Maybe I should undefine it? Where would I do it?

I forgot to mention that I am on 64bit. Now I see that if CPU64 is defined, the line that causes the error would be ignored.
Where should I define COU64? I tried in Projects->Options, but that givesme an error in NexusDB4.

If you don't what LVCL is, you don't need it.

It should never be defined for standard process.

I guess there is something wrong with your setup.
I don't have problem on my side:

HI.
Mine is win64. However I have no idea of what "Switches=-B -Q -GD -O\dev\lib\SQLite3 -R\dev\......" means. I just put all source files in a folder and I add the files I need to the Project. Do I need to run some kind of installation instead?

Did you read the doc about Delphi setup?
