Nope, you're still making the same mistake:
#include <gtk/gtk.h>
#include <stdio.h>
int main() {
printf("%d.%d.%d\n",
(gtk_major_version),
(gtk_minor_version),
(gtk_micro_version));
return 0;
}
$ gcc -pthread -o gtktest gtktest.c `gtk12-config --libs` `gtk12-config --cflags`
$ ./gtktest
1.2.10
By the way:
$ gtk12-config --cflags
-I/usr/X11R6/include/gtk12 -I/usr/local/include/glib12 -I/usr/local/include -I/usr/X11R6/include
If GTK applications on FreeBSD require -pthread to link successfully, gtk12-config
should probably include this option when asked for --cflags.

All of the references to missing pthread functions should've caught your
attention.
