When is the application's FXRegistery used/read? and ~/.foxrc not read? (Linux/x86-64 recent Debian or Ubuntu)

Hello

Consider (for Linux, Debian/sid, x86-64 or Ubuntu 23.04) the open source 
code on https://github.com/RefPerSys/guifox-refpersys commit 0ac2c34 
<https://github.com/RefPerSys/guifox-refpersys/commit/0ac2c345e085107f41df5bb54f077f8b26ceedd9>

The FOX toolkit is shown by that example (rimski is my personal desktop, 
Ubuntu 23.04 Mantic Minotaur,  AMD Ryzen Threadripper 2970WX)

rimski.x86_64 ~/guifox-refpersys 20:48 .1 % ./foxrps --version
./foxrps version information (on rimski):
      git 368e52da967d35a8af8ac6cadb0d14caac32ecd1+
      built Sep 20 2023@20:26:39
      for OS: GNU_Linux and arch x86_64
      compiled on rimski
      compiled for FOX 1.7.84, running 1.7.84

I don't understand why the FXRegistery is not loaded, having some empty 
$HOME/.foxrc

If I strace the process, this ~/.foxrc file is not even open-ed, why?

Regards from near Paris in France.


NB. guifox-refpersys is a tentative GUI client, using FOX 1.7.84 
compiled from source code, for the RefPerSys <http://refpersys.org/> 
open source inference engine project on 
https://github.com/RefPerSys/RefPerSys
