HOWTO init Tcl on Windows ?

[Rainer2]

Hi,

I have extendet my project

http://pvbrowser.sourceforge.net

(Process Visualisation)
with VTK (Visualization Toolkit)

http://www.kitware.com

It all works fine under Linux.
But on Windows I can't initialize the Tcl interpreter.
Wish83 is running also VTK !!!
Versions: VTK 4.0 from User's Guide CD including Tcl/Tk 8.3
WindowsXP
VC++ 6.0

What's the problem ? I couldn't find a FAQ for my problem.
Is it a problem of tcl83 with WindowsXP ?

Please give me a hint.

#include "stdafx.h"

int APIENTRY WinMain(HINSTANCE hInstance,

Tcl_Interp *interp;

interp = Tcl_CreateInterp(); // the returned interp looks ok
if(Tcl_Init(interp) == TCL_ERROR)
{
return TCL_ERROR; // here I get an error
}

return 0;
}

Additional Information:

The error is ENOENT "No such file or directory"

So what may be missing (wish83 runs) ?

I don't know if this will fix it or not, but in recent years you need to call Tcl_FindExecutable() before creating your interpreter. Here's the line of code you'll need:

Tcl_FindExecutable(argv[0]);

As the documentation for the function says: "The Tcl_FindExecutable procedure computes the full path name of the executable file from which the application was invoked and saves it for Tcl's internal use. The executable's path name is needed for several purposes in Tcl. For example, it is needed on some platforms in the implementation of the load command. It is also returned by the info nameofexecutable command."

You can find out a bit more about this on the Tcl'ers Wiki,

http://wiki.tcl.tk.

Specifically, you might want to start with the page "Building a custom tclsh,"
