Re: [gtk-osx-users] Newer macOS version (12.0) than being linked (11.0)

[Gabriele Greco <gabrielegreco gmail com>]

The warning you have are almost harmless, they said just that the MAIN application is built with an OSX sdk older than the libraries it uses. This can be a problem since the application will be able to run on macos 11 but the library may use some macos12 only symbols.

I usually build with 10.10 MACOSX_DEPLOYMENT_TARGET env variable, both the libraries (gtk, ffmpeg...) and the application.

Please note that the C target (so most GTK APIs) has an ABI that is almost freezed, but if you use also C++ libraries (ie GTKmm) having libraries compiled against a newer SDK than the application may be a problem.

Hello,

My configuration is macOS 12, I just built:

% jhbuild bootstrap-gtk-osx
% jhbuild build python3
% jhbuild build meta-gtk-osx-bootstrap

When I build my program I got a lot of:
ld: warning: dylib (/usr/local/xnadalib-2021/lib/libgtk-3.dylib) was built for newer macOS version (12.0) than being linked (11.0)

It is not so clear.
What is this actually meaning?

This seems just to be a warning but my program shows some erroneous GTK executions.

How to deal with it?

NB : with GTK which was built when I was on macOS 11, I have no warning and no issue to build my program on macOS 12.

Have you installed homebrew? If so, rename or remove it while compiling gtk-osx.

No Paul, I haven't.

OK, interesting. It seems that you do have something in /usr/local though - do you know what it is?

I found only CLI tools like BBEdit or OSXFuse.

I have MacPorts installed in /opt/local but not in PATH.
Should I delete XDG_CACHE_HOME folder before building GTK?

I don't know, sorry. My feeling is that you shouldn't need to do so.

When looking in environnement variables in jhbuild shell, I found:
[JH] % echo $MACOSX_DEPLOYMENT_TARGET 
12

Should I specify 11 in calling setup_sdk in jhbuildrc-custom?

If so, I wonder: why the link message is issued as I have rebuilt all on macOS 12?

The link message is saying that whatever you're trying to link was compiled with macosx-version-min=11.0 while libgtk-3.dylib was compiled with macosx-version-min=12.0. Did you perhaps forget to reconfigure your project after rebuilding everything else?

Hello John,

I aim to build the GTKAda bindings with the fixed version of GTK for macOS 12.
I dig in my building configuration without success.
In fact the issue is coming from my Ada compiler which is stuck to macOS 11, the internal compilation is done with -mmacosx-version-min=11.0.0.

So I got:
otool -l /usr/local/xnadalib-2021/lib/gtkada/gtkada.relocatable/gtkada/libgtkada.dylib
     cmd LC_BUILD_VERSION
 cmdsize 32
platform 1
   minos 11.0
     sdk 10.17

Thus the warning.

The test program is nevertheless running but fails with:
Gtk:ERROR:../../../../gtk+-3.24.30/gtk/gtkiconhelper.c:494:ensure_surface_for_gicon: assertion failed (error == NULL): Failed to load /usr/local/xnadalib-2021/share/icons/Adwaita/24x24/status/image-missing.png: Unrecognized image file format (gdk-pixbuf-error-quark, 3)
Bail out! Gtk:ERROR:../../../../gtk+-3.24.30/gtk/gtkiconhelper.c:494:ensure_surface_for_gicon: assertion failed (error == NULL): Failed to load /usr/local/xnadalib-2021/share/icons/Adwaita/24x24/status/image-missing.png: Unrecognized image file format (gdk-pixbuf-error-quark, 3)

However the GTKAda source code is the same since I built it on macOS 11 with success.

Well now, should I specify setup_sdk(target="11") in jhbuildrc-custom and rebuild all GTK stuff?

The gdk-pixbuf errors have to do with not being able to find its modules. That might be because you need to run gdk-pixbuf-query-loaders --update-cache (in a jhbuild shell of course!) or you need to set GDK_PIXBUF_MODULEDIR to point at where it is, see http://manpages.ubuntu.com/manpages/impish/man1/gdk-pixbuf-query-loaders.1.html.

John Ralls
