如何在macOS上运行GTK 3(hello, world)

首先,安装 Homebrew

然后,brew install gtk+3

随后,查阅GTK的官方文档,写Hello, world:

// hello.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_all (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;
}

然后编译:

gcc `pkg-config --cflags gtk+-3.0` -o hello hello.c `pkg-config --libs gtk+-3.0`

当前目录下就有了hello二进制可执行文件,执行即可:

    Package libffi was not found in the pkg-config search path.
    Perhaps you should add the directory containing `libffi.pc’
    to the PKG_CONFIG_PATH environment variable
    Package ‘libffi’, required by ‘gobject-2.0’, not found
    hello.c:1:10: fatal error: ‘gtk/gtk.h’ file not found
    #include
