TclError: couldn't load file "vtkTkImageWindowWidget": invalid argument

[David Gobbi]

Hi Heather,

The python vtkTkRenderWidget.dll and vtkTkImageWindowWidget.dll are
not built under Windows (yet) - you have to build them yourself.  
I'll attach the instructions below.

These instructions do not work with the nightly releases because
they build VTK with tcl/tk 8.2 (Python is only compatible with 8.0).
There is a way around this -- you can copy vtk/pcmaker/xlib from
vtk2.4 and force VTK to build with tcl/tk 8.0.

Instructions:

Assuming you have installed VTK in C:\vtk, open a DOS shell and cd to
C:\vtkbin\vtkpython.  Then do the following (should put this in a .bat file):

cl.exe /D "STRICT" /nologo /MD /O2 /I "C:\Progra~1\DevStudio\VC\\include"
/I "C:\vtk\common" /I "C:\vtk\graphics" /I "C:\vtk\imaging" /D "NDEBUG" /D
"WIN32" /D "_WINDOWS"  /I "C:\vtk\pcmaker\xlib" /I "\..\generic" /D
"VTK_USE_PATENTED" /I "C:\vtk\patented"  /D "VTK_USE_CONTRIB" /I
"C:\vtk\contrib"  /D "VTK_USE_LOCAL" /I "C:\vtk\local"  /D "_WINDLL" /D
"_MBCS"  /D "VTK_LEAN_AND_MEAN" /D VTK_PYTHON_BUILD /Foobj\ /c
"C:\vtk\graphics\vtkTkRenderWidget.cxx"

link.exe obj\vtkTkRenderWidget.obj /dll /incremental:no
/pdb:vtktkrenderwidget.pdb /machine:I386 /out:..\lib\vtkTkRenderWidget.dll
/implib:..\lib\vtkTkRenderWidget.lib
/libpath:"C:\Progra~1\DevStudio\VC\\lib"
"C:\Progra~1\DevStudio\VC\lib\gdi32.lib"
"C:\Progra~1\DevStudio\VC\lib\user32.lib" /nologo /version:1.3
/subsystem:windows "C:\PROGRA~1\Tcl\lib\tk80.lib"
"C:\PROGRA~1\Tcl\lib\tcl80.lib" ..\vtkdll\vtkdll.lib
