GtkWidget *janela; gtk_init(&argc, &argv); janela = gtk_window_new(GTK_WINDOW_TOPLEVEL); gtk_window_set_title(GTK_WINDOW (janela), "Alo Mundo"); gtk_widget_show(janela); gtk_main(); return 0;

Can anyone help?

Those are linker errors. I don't see where you're linking in the GTK library.
I think this is enough here (I'm beginner...):
-L / home/Gabriel/DS-5-Workspace/distribution/filesystem/armv5t_mtx/usr/lib \ -L / home/Gabriel/DS-5-Workspace/distribution/filesystem/armv5t_mtx/usr/lib/glib-2.0/include \ -L / home/Gabriel/DS-5-Workspace/distribution/filesystem/armv5t_mtx/usr/lib/gtk-2.0/include
"I think this is enough here "
OK, if you say so.
???
"???"
Well, I was thinking that you'd want to specify what library to link to, not just where to look for unnamed libraries.
You wrote that you thought the where was enough, so I have nothing more to add.
I think there was a misunderstanding, I put the following lines in the makefile:

It continues:
My doubt is whether the procedure was correct, if so, does anyone know what the libs that I put in patches? If not, what the correct procedure?
"My doubt is whether the procedure was correct ..."
I also was doubting whether your procedure is correct because I could only see your "-L" specifications for where the linker should look for libraries and could not find the "-l" specification for which libraries to link.
