Hi everyone!
I have been figthed with ns older versions.
But now I do not have the idea what can I do:
During ns-allinone-2.1b7a installation I have:

tclcl-mappings.h: In static member function ‘static int
TclObjectHelper<T>::dispatch_(void*, Tcl_Interp*, int, char**)&#8217;:
tclcl-mappings.h:51: error: incomplete type &#8216;Tcl&#8217; used in nested
