Compilation problems with gtk/gl configure

Hi, last night I download amaya-fullsrc-9.52.tgz and then I execute 
configure script with this parameters --with-gl --with-gtk, then when I 
do the make I get this error:
[...]
make[1]: Entering directory `/root/Amaya/obj/thotlib'

make[1]: *** [base/global.o] Error 1
make[1]: Leaving directory `/root/Amaya/obj/thotlib'
make: *** [thotlib] Error 2

To solve this I include gdk_imlib.h and gdk.h in picture.h file:
#ifdef _GTK
#include <gdk_imlib.h>
#include <gdk/gdk.h>
#endif

After this I get another error:

This is the source of appdialogue.c that have the problem:

/********************************************************************/
#ifdef _GL
#ifndef _NOSHARELIST
    if (GetSharedContext () == -1)
    {
#endif /*_NOSHARELIST*/
        drawing_area = GetGLArea ();
#ifdef _NOSHARELIST
        g_print ("Warning: upgrade your Opengl implementation (ie: Mesa) 
to get group opacity!\n");
#else /*_NOSHARELIST*/
        SetSharedContext (frame);
    }
    else
        drawing_area = gtk_gl_area_share_new (AttrList,
                            GTK_GL_AREA (FrameTable[GetSharedContext 
()].WdFrame)); //line:2990
#endif /*_NOSHARELIST*/
#else /*  _GL */
#ifdef _GTK
    drawing_area = gtk_drawing_area_new ();
#endif /* _GTK */
#endif /*  _GL */
/********************************************************************/

'G_TYPE_CHECK_INSTANCE_CAST' is part of glib-object, but its doesn't 
included in appdialogue.
I don't know how to solve this.. help!

Bye! :) (sorry my very poor english..)
