[vtkusers] Help with tcl interpreter

[shahid]

You probably need to first check that you Interp process is initialized
properly
	code=Tcl_Eval(tclinterp,"info library"); # returned path must include path
to vtk files
                                               #else "package require vtk"
shall fail
doing
	Tcl_EvalFile(tclinterp, "your_tcllibpath/init.tcl"); # may help to
initialize the interpreter properly

Hope this shall solve your problem.

Subject: [vtkusers] Help with tcl interpreter


Hello

I am trying to use Tcl_Interp and Tcl_EvalFile to evaluate a tcl script from
a c++ file. My code looks like this:

Tcl_Interp *tclinterp;
tclinterp = Tcl_CreateInterp();

int code = Tcl_EvalFile(tclinterp, "myTclScript.tcl");

if (code!=TCL_OK) {
  return TCL_ERROR;
}

The problem is that Tcl_EvalFile is never TCL_OK and always returns an
error, i.e. myTclScript.tcl can not be evaluated. When my tcl script has
been run by the interpreter I would like to access some actors generated in
the tcl script.

Does anyone have any experience on this and can see what I am doing wrong?

Sincerely
Johanna
