我已阅读我使用的 GTK for GTK4 的安装说明
sudo dnf install gtk4 gtk4-devel
Hello, World 示例的代码是
#include <gtk/gtk.h>
static void
print_hello (GtkWidget *widget,
gpointer data)
{
g_print ("Hello World\n");
}
static void
activate (GtkApplication *app,
gpointer user_data)
{
GtkWidget *window;
GtkWidget *button;
window = gtk_application_window_new (app);
gtk_window_set_title (GTK_WINDOW (window), "Window");
gtk_window_set_default_size (GTK_WINDOW (window), 200, 200);
button = gtk_button_new_with_label ("Hello World");
g_signal_connect (button, "clicked", G_CALLBACK (print_hello), NULL);
gtk_window_set_child (GTK_WINDOW (window), button);
gtk_window_present (GTK_WINDOW (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;
}
我使用了 GCC 的编译功能:
gcc -o hello-world-gtk hello-world-gtk.c `pkg-config --cflags --libs gtk4`
但是这个错误呈现
gtktest.c:1:10: fatal error: gtk/gtk.h: No such file or directory
1 | #include <gtk/gtk.h>
| ^~~~~~~~~~~
如我所见,我应该安装了所有必需的软件包,但我不确定为什么编译器无法提取 gtk 库。任何帮助都是极好的。
