With Intel ifort/ifx, gtkbuilder, gtkbuilder2 and gtkf-sketcher could not open gtkbuilder.glade

Describe the bug
When gtk-fortran is built with ifort, gtkbuilder, gtkbuilder2 and gtkf-sketcher don't work and just print that error:
Could not open gtkbuilder.glade
Your system:
- OS version: Ubuntu 21.04 64 bits
- Compiler version: ifort (IFORT) 2021.2.0 20210228
- GTK branch: tested only in gtk4.
Additional context
No problem with gfortran.
Under MSYS2/Windows 10, and compiled with gfortran, gtkbuilder don't work and prints the same message.
But gtkbuilder2 and gtkf-sketcher have no problem, probably because they contain the GCC$ ATTRIBUTES DLLEXPORT.
gtkbuilder.f90 has been removed from the gtk4 branch, as it is now a duplicate of gtkbuilder2.f90 (they were using two different GTK 3 functions, removed in GTK 4).
Same problem with GTK 4.4 and ifort 2021.4.0
After replacing gtk_builder_add_from_file() by gtk_builder_new_from_file(), the ifort 2021.4.0 error message is:
(process:24055): Gtk-ERROR **: 18:43:29.082: failed to add UI from file gtkbuilder.glade: No function named `hello`.
Trappe pour point d'arrêt et de trace (core dumped)although there is a subroutine hello(widget, gdata ) bind(c) in the code.
Same error message now with GTK 4.6.2: GFortran 12.0.1 in Fedora Rawhide, GFortran 11.2.0 in FreeBSD 13.
[osboxes@localhost examples]$ ./gtkbuilder2
(process:14648): Gtk-ERROR **: 14:56:45.953: failed to add UI from file gtkbuilder.glade: No function named `hello`.

builder=gtk_builder_new_from_file("gtkbuilder.glade"//c_null_char)But it works under MSYS2/Windows 10, with GFortran 11.2.0 and GTK 4.6.2.
No problem with GTK 4.6.3 and GFortran 12.0.1 in latest Fedora Rawhide.
Same problem with ifx 2022.1.0 20220316 ; gtk-fortran 4.2.1, GTK 4.6.3
The same error message occurs under MSYS2/Windows 10 if I remove the !GCC$ ATTRIBUTES DLLEXPORT :: attributes in gtkbuilder2.f90, and use GFortran to build it.
For Intel Fortran, under Windows we should use: !DIR$ ATTRIBUTES DLLEXPORT :: object [ , object ] ...

Could it be because GTK is not built with an Intel compiler?
Or should we use a specific Intel compiler flag?
