Yesterday I fixed these errors:
**** language not recognized: C [macro <ev_gtk.h>] | "eif_argv.h"
[GIAAA] internal error.
----
**** language not recognized: C Macro use <ev_gtk.h>
The CATCALL messages are just warnings.
The Dynamic type set are more problematic, but they should not prevent from generating the executable.
So if you get the latest version of the repository, you should be able to generate an executable.

The semicolon is also missing in the Eiffel code:
frozen gtk_paned_set_wide_handle (a_paned: POINTER; a_wide: BOOLEAN)
external
"C inline use <ev_gtk.h>"
alias
"[
#if GTK_CHECK_VERSION(3,16,0)
gtk_paned_set_wide_handle ((GtkPaned*) $a_paned, (gboolean) $a_wide)
#endif
]"
ensure
is_class: class
end
I'll see what I can do to let the Eiffel compiler add this missing semicolon in the generated C code.

I manually add ; at line 274 of
/Eiffel_23.09/library/vision2/implementation/gtk3/support/externals/gtk3.e
as temp fix.

I provide them as needed. Sometimes they don't end up in the right eif_*.h file my assumption was wrong (they were added here because it allowed one ISE library to compile, but they need to be moved somewhere else to compile another ISE library). That's what happened with eif_wean and others.

I figured out what is the equivalent of eif_id_object in Gobo. So I will be able to provide a fix.

If we can make gec compile /Eiffel_23.09/examples/docking/simple, then we can test its behavior under gec.

I'm sure I'm using zig cc now.
and I have tried all the different --gc=no --capability=concurrency=none on / off combination options. they all segfault on my system.
I will try WSL later in my afternoon.
Thank you so much for the help. Hope you have a good night.

there is a good chance that the program will not work as expected (and probably crash).
I can see how to figure out what would be the dynamic type set of eif_object_from_c, but it will take some time and effort to implement it in gec.

On a second thought: I don't need the GUI application to run (correctly), I only need to be able to build the project binary: I will just create a object, and do some reference equality check and print, that's all.
Esp., I'm trying this example now: /Eiffel_23.09/examples/docking/simple
Is it possible to make the gec build work for this project?
Currently the error is:

It looks like you chose some Eiffel application which uses C code which itself relies on ISE Eiffel's runtime. Not the best choice to start with :-)
I'll address this issues one after the other...

How to let the build see these macros first? (Ideally, GOBO should also define these as functions instead of macros, so user won't have link error when compile ISE project.)
And what's the GOBO equivalent of eif_id_object?

fixed by add to /gobo/tool/gec/backend/c/config/gcc.cfg link:
`pkg-config --libs gdk-3.0` `pkg-config --libs gtk+-3.0` `pkg-config --libs glib-2.0` `pkg-config --libs gmodule-2.0` `pkg-config --libs x11`
I wonder what they do for that in the ISE Eiffel compiler. It should be somewhere in the ECF files!
Ideally gec should add all these on the fly when needed, and not all the time even for non-gtk applications.

How to let the build see these macros first?
And what's the GOBO equivalent of
eif_id_object?
For eif_adopt, eif_protect and eif_wean, you should get and build the latest version of gec. It works for the cURL example.
For eif_id_object I need to look at the ISE Eiffel code to see what it does in order to provide an equivalent implementation in gec.

I'm using the latest version of gec:

gec version xx.xx.xx+xxxxxxxxx
Ideally, GOBO should also define these as functions instead of macros, so user won't have link error when compiling ISE project.

Why? You would still have to make sure that the C code of these functions are compiled into the resulting executable.
They are also macros in the ISE Eiffel implementation.

Yes, I'm using this, just synced 10-minutes ago. Maybe you want to update gec version xx.xx.xx+xxxxxxxxx with some stamp even during dev.

Why? You would still have to make sure that the C code of these functions are compiled into the resulting executable. They are also macros in the ISE Eiffel implementation.
Oh, then why we have link error here? For macros, it will be expanded on the spot, at most compile error, but not link error.
Basically what I mean is the GOBO external C impl structure better to match ISE external C impl structure, so no link surprise.

Yes, so they are macros in ISE. You get links error because I did not include these macros in the right header files. But this can be fixed easily. The eif_*.h in Gobo are just here to make ISE's code compile with gec. But I will certainly not replicate ISE's runtime in Gobo.

In other worlds, the eif_*.h files are a bridge between the Gobo Eiffel runtime and what is expected to compile ISE's libraries.

in main_window.e, method prepare_content_1(), add
local
zone: SD_PLACE_HOLDER_ZONE
impl, impl2: EV_WIDGET_I
and append at the end of do:
io.put_string ("Hello, diamond!%N")
create zone.make(content_1, manager)
impl := zone.implementation
impl2 := zone.implementation_upper_zone
print($impl)
io.put_string("%N")
print($impl2)
io.put_string("%N")
if zone.implementation /= Void then
if zone.implementation = zone.implementation_upper_zone then

end
if zone.implementation_upper_zone.is_equal(zone.implementation) then
io.put_string ("zone.implementation_upper_zone.is_equal(zone.implementation)%N")
