Thank you for message. I had CC=cc and CC=gcc but with the same problems. Now I have builded myself Tcl with threads and shared 8.4.1 version and I installed under /export/home/stefan/tcltk
then when I compile aolserver I just provide --with-tcl=/export/home/stefan/tcltk/lib for Tcl definition. aolserver 3.0 compiles fine. stefan
