Hi, I have installed fpc and Lazarus with latest version of fpcupdeluxe (https://github.com/LongDirtyAnimAlf/fpcupdeluxe) - v2.4.0e, selecting the stable version. It installs fpc 3.2.2 and Lazarus v3.4. (Pic below)

Adding superobject to a project, does not compile:

Custom Attribute is supported from compiler 3.3.1 ( your 3.2.2 ). https://wiki.freepascal.org/Custom_Attributes

Try disabling "{$define HAVE_RTTI}" in "superobject.pas". For example, like this:

{$IFDEF FPC}
  {$define HAVE_INLINE}
  ...
  {$if (fpc_version>3) or ( (fpc_version=3) and ((fpc_release>3) or ((fpc_release=3) and (fpc_patch>0))) )}
    {$define HAVE_RTTI} // optional
  {$ifend}
...

Thanks, that works, and I can compile my project fine on Windows 10.

However, I also installed fpcupdeluxe on wsl (ubuntu). When I try to compile on that system (linux 64), I get this error:
