旧日回忆

#include <glib.h>
#include <stdio.h>
int
main (int argc, char *argv[])
{
  if (!GLIB_CHECK_VERSION (2, 16, 3))
    g_error ("GLib version 2.16.3 or above is needed");
  else
    printf ("GLib version is %d.%d.%d\n", glib_major_version,
            glib_minor_version, glib_micro_version);
  return 0;

}

编译gcc `pkg-config --cflags --libs glib-2.0` version.c
执行./a.out
结果GLib version is 2.18.0
