[MACTCL] Problem with porting an app to AquaTclTk..

[Alexander C. <Ale...@gm...>]

Hi!

I am sorry that I have disturb you, but since I have no experience with 
Tcl/Tk I need a good tip from an expert.

I am currently trying to port Berkerlys NetworkSimulator (ns) to 
AquaTcl/tk. So far, so good, the simulator passes all
tests. But I have problems to get the visual analyser nam to work. 
After playing around with the XCode debugger, it seems that I found
the problem. It does not find the Tk extension.

This is the code:

first:
#if TCL_MAJOR_VERSION < 8
         Tcl_SetVar(interp, "tcl_library", "./lib/tcl7.6", 
TCL_GLOBAL_ONLY);
         Tcl_SetVar(interp, "tk_library", "./lib/tk4.2", 
TCL_GLOBAL_ONLY);
#else
         Tcl_SetVar(interp, "tcl_library", "", TCL_GLOBAL_ONLY);
         Tcl_SetVar(interp, "tk_library", "", TCL_GLOBAL_ONLY);

         // this seems just a hack, should NOT have hard-coded library 
path!
         // why there's no problem with old  TCL/TK?
         // xuanc, 10/3/2003
         //Tcl_SetVar(interp, "tcl_library", "./lib/tcl8.0", 
TCL_GLOBAL_ONLY);
         //Tcl_SetVar(interp, "tk_library", "./lib/tk8.0", 
TCL_GLOBAL_ONLY);
#endif

and later (where it exits):

	if (Tk_Init(tcl.interp()) == TCL_OK)
		tk = Tk_MainWindow(tcl.interp());
	if (tk == 0) {
		fprintf(stderr, "nam: %s\n", interp->result);
		exit(1);

the error message:
nam: invalid command name "tcl_findLibrary"

Do you have any ideas whats going on? Where does AquaTcl search for 
extensions?

regards,
   Alexander



Cheers,

Daniel
