[gtk4]

[tasiek30]

Recently I decide to try GTK4 (currently I am using wxWidgets, but now i need something with more modern feel and look).

I’m working on Windows 10 Pro 64bit

I get library directly from MSYS:

pacman -S mingw-w64-i686-gtk4

Succesfully i compile example with mingw32 (path variable have C:\msys64\mingw32\bin):

gcc pkg-config --cflags gtk4 -o test test_c.c pkg-config --libs gtk4

test_c.c:

#include <gtk/gtk.h>
static void
activate (GtkApplication* app, gpointer user_data)
{
GtkWidget *window;
window = gtk_application_window_new (app);
gtk_window_set_title (GTK_WINDOW (window), “Window”);
gtk_window_set_default_size (GTK_WINDOW (window), 200, 200);
gtk_widget_show (window);
}
int main (int argc, char **argv)
{
GtkApplication *app;
int status;

app = gtk_application_new (“org.gtk.example”, G_APPLICATION_FLAGS_NONE);
g_signal_connect (app, “activate”, G_CALLBACK (activate), NULL);
status = g_application_run (G_APPLICATION (app), argc, argv);
g_object_unref (app);

return status;
}

But aplication won’t run:

The procedure entry point vkAcquireNextImageKHR could not be located in the dynamic linked library C:/msys64/mingw32/bin/libgtk-4-1.dll

So i decide to try x64 version:

pacman -S mingw-w64-x86_64-gtk4

and compile with mingw64 (path variable now have C:\msys64\mingw64\bin):

gcc pkg-config --cflags gtk4 -o test test_c.c pkg-config --libs gtk4

and application sucessfully run.

Also i try to use mingw32 and GTK3 :

gcc pkg-config --cflags gtk+-3.0 -o test test_c.c pkg-config --libs gtk+-3.0

and application sucessfully run.

Is it possible to run GTK4 32 bit application on 64 bit machine?

It is, it just looks like gtk4 for 32 but needs to be rebuilt maybe.

Rebuild will be in the next update.
