无法理解kern.osversion`16.7.0'

Question

I am current trying to compile this simple code:

#include <gtk/gtk.h>

int main(int argc, char *argv[]) {

GtkWidget *window;
gtk_init(&argc, &argv);
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_widget_show(window);
g_signal_connect(window, "destroy",
  G_CALLBACK(gtk_main_quit), NULL);  
gtk_main();
return 0;
}

I am trying to run this command:

gcc -o simple simple.c `pkg-config --libs --cflags gtk+-2.0`

But I receiving this EM:

couldn't understand kern.osversion `16.7.0'

My system macOS version is 10.12.6

Answer 1

Ok I guess I found out what the issue was. The gcc version I was using was old although I installed a newer version through brew. So what I did is to edit the Path variable like this:

export PATH=/usr/local/bin:$PATH
