Create a simple hello-world application - stm32mpu

 

1. 폴더 만들기

PC $ mkdir /home/본인PC이름/STM/Developer-package/stm32mp1-openstlinux-5.15-yocto-kirkstone-mp1-v22.11.23/sources/gtk_hello_world_example

 

 

2. 폴더로 이동

PC $ cd /home/본인PC이름/STM/Developer-package/stm32mp1-openstlinux-5.15-yocto-kirkstone-mp1-v22.11.23/sources/gtk_hello_world_example

 

 

3. gtk_hello_world.c 생성

#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;
  GtkWidget *button_box;

  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_box = gtk_button_box_new (GTK_ORIENTATION_HORIZONTAL);
  gtk_container_add (GTK_CONTAINER (window), button_box);

  button = gtk_button_new_with_label ("Hello World");
  g_signal_connect (button, "clicked", G_CALLBACK (print_hello), NULL);
  g_signal_connect_swapped (button, "clicked", G_CALLBACK (gtk_widget_destroy), window);
  gtk_container_add (GTK_CONTAINER (button_box), button);

  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;
}

 

 

4. Makefile 생성

PROG = gtk_hello_world
SRCS = gtk_hello_world.c

CLEANFILES = $(PROG)

# Add / change option in CFLAGS and LDFLAGS
CFLAGS += -Wall $(shell pkg-config --cflags gtk+-3.0)
LDFLAGS += $(shell pkg-config --libs gtk+-3.0)

all: $(PROG)

$(PROG): $(SRCS)
	$(CC) -o $@ $^ $(CFLAGS) $(LDFLAGS)

clean:
	rm -f $(CLEANFILES) $(patsubst %.c,%.o, $(SRCS))

 

 

5. cross-compile

PC $ make

 

에러나서 구글 검색해 보니 gtk3을 설치하라고 한다.

PC $ sudo apt-get install libgtk-3-dev

 

설치 후 다시 compile

 

6. 실행

보드로 실행 파일 업로드

PC $ scp gtk_hello_world root@172.10.6.98:/usr/local

 

weston으로 실행

Board $ cd /usr/local/
Board $ su -l weston -c "/usr/local/gtk_hello_world"
