compilation failed : G_APPLICATION_DEFAULT_FLAGS not declared

[tissatussa]

that variable is at the end of the Makefile : it's not declared and i get an error :

i hope you can solve this, i'm curious how your engine plays ..
btw. what's the name of the engine ? "Yonder" ?

greetings from Holland !

Hi Roelof, thanks for reaching out!

I suppose you have an older GTK4 release. Try updating with sudo apt install libgtk-4-dev. If that doesn't work, please provide the output for pkg-config --cflags --libs gtk4.

You can still try out the UCI-compatible engine binary (make main).

[tissatussa]

libgtk-4-dev seems to be installed on my OS .. here's the output you suggested :

$ pkg-config --cflags --libs gtk4

can this info help you to solve my issue ?

[sohamkorade]

I am not exactly sure if it helps. Here is my output for comparison:

$ pkg-config --cflags --libs gtk4
-I/usr/include/gtk-4.0 -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -I/usr/include/harfbuzz -I/usr/include/freetype2 -I/usr/include/libpng16 -I/usr/include/libmount -I/usr/include/blkid -I/usr/include/fribidi -I/usr/include/cairo -I/usr/include/pixman-1 -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/x86_64-linux-gnu -I/usr/include/webp -I/usr/include/graphene-1.0 -I/usr/lib/x86_64-linux-gnu/graphene-1.0/include -mfpmath=sse -msse -msse2 -pthread -lgtk-4 -lpangocairo-1.0 -lpango-1.0 -lharfbuzz -lgdk_pixbuf-2.0 -lcairo-gobject -lcairo -lvulkan -lgraphene-1.0 -lgio-2.0 -lgobject-2.0 -lglib-2.0

Can you try compiling after replacing G_APPLICATION_DEFAULT_FLAGS with G_APPLICATION_FLAGS_NONE?

https://www.reddit.com/r/GTK/comments/105kri7/proper_way_to_deal_with_deprecated_g_application/

[tissatussa]

that works !
i'm playing a game now in the gui, which looks nice !
however, first i had to create a folder archive in root ?!

that refer is awesome : how to deal with those deprecated variables on all OS - didn't know that, never used it.

the main UCI binary runs fine in CuteChess, it just won its first game 10m5s !
