[vtkusers] Issues with VTK 4.2

[Tom G. Smith (Smitty)]

Hello vtkusers at public.kitware.com,

I just installed VTK 4.2 on a RedHat 9.0 system.  We've been using
VTK for a number of years now, since VTK Version 2.4, and it's never
gotten any easier to install and configure.  Here are several
issues:

1.	During the cmake -i, it prompts you to BUILD_SHARED_LIBS,
	with the default of OFF.  If you don't change it to ON and
	subsequently override VTK_WRAP_PYTHON to ON, it waits
	another 30 prompts or so before it dies with the error,
	"VTK_WRAP_PYTHON requires BUILD_SHARED_LIBS to be ON."
	Then you have to go through the whole tedious set of prompts
	from the beginning again.

2.	I left VTK_USE_HYBRID and VTK_USE_PARALLEL both at OFF, but
	set VTK_WRAP_TCL to ON.  When the cmake finished and I
	try to run any of the Tcl examples, they work, but I get
	these messages every time:

	bash-2.05b$ vtk /opt/vtk/Examples/Modelling/Tcl/faultLines.tcl
	can't find package vtkHybridTCL 4.2
	can't find package vtkParallelTCL 4.2

3.	It works, but I get these messages if I run vtk anywhere but
	directly at the console.  These messages have been around
	since VTK 4.0.	They did not appear prior to that version.

	bash-2.05b$ vtk /opt/vtk/Examples/Modelling/Tcl/faultLines.tcl
	Xlib: connection to ":0.0" refused by server
	Xlib: No protocol specified

4.	Some of the tcl examples don't work at all. I've only listed a few
	that I tried which failed; there are lots more that don't work:

	bash-2.05b$ vtk /opt/vtk/Examples/Modelling/Tcl/procrustesAlignment.tcl
	Error in startup script: invalid command name
	"vtkProcrustesAlignmentFilter" while executing
	"vtkProcrustesAlignmentFilter procrustes1" (file
	"/opt/vtk/Examples/Modelling/Tcl/procrustesAlignment.tcl"
	line 49)

	bash-2.05b$ vtk /opt/vtk/Examples/Modelling/Tcl/hello.tcl
	can't find package vtkHybridTCL 4.2 can't find package
	vtkParallelTCL 4.2 Error in startup script: invalid command
	name "vtkImplicitModeller" while executing "vtkImplicitModeller
	imp" (file "/opt/vtk/Examples/Modelling/Tcl/hello.tcl" line 24)
