[Paraview] InitializeTcl failed/no $DISPLAY environment variableerrors (paraview on intel mac)

Wed Feb 28 16:50:46 EST 2007

I've run into similar behavior before.  try setting display to
localhost:0.0 or yourPublicIP:0.0 or yourHostName:0.0

environment variableerrors (paraview on intel mac)

	Paul,

	My fault for not being more specific.  I am using an intel mac
(10.4.8), using a bash shell and the computer is local.

	It looks like i hadnt set my DISPLAY env. variable.  When i
typed in 

	    echo $DISPLAY

	i was given an empty line (guessing that this wasnt set
already).  I went ahead an then set the variable to the local dispaly

	    export DISPLAY=:0.0

	Then, i tried again to launch paraview.  This time, i was
greeted with a new error message.

	    Paraview error: InitializeTcl failed
	    Tk_Init error: this isn't a Tk applicationcouldn't connect
to display ":0.0"

	(i left applicationcouldn't as one word, since this is how the
error was displayed).  

	More info (compiled from previous posts).  I have tried running
paraview (2.6) from the precompiled binary.  I get the same message.  I
have also tried running paraview (2.6) on a powerpc (using the powerpc
precompiled binary).  Again, same error messages.

	Any more ideas?

		O.K.  I did not know if you had truncated the error
message or not.  Sometimes I do that to make it easier to read.  So
let's try the simple thing first: Have you set your DISPLAY environment
variable?  Making the assumption that you are new to Linux, try the
following two commands.  The first prints out the value of the DISPLAY
environment variable.  The second sets the DISPLAY environment variable
to the local display.  

		     echo $DISPLAY
		     export DISPLAY=:0.0

		Depending on the computer you are using (I assumed it
was Linux), what shell you are using (I assumed sh or bash), and whether
or not the computer is local or remote, it may or may not work.  Let me
know the whether my assumptions were correct or not and I can help you
more.

			Paul,

			Thanks for the reply.  The error message i am
getting is only:

			    ParaView error: InitializeTcl failed 
			    TK_Init error: no display name and no
$DISPLAY environment variable 

			There is no mention of the tcl_library.  Should
i try to set that variable anyway???  How do i go about doing this?

			Thanks again for any help

				Is this the problem that you are seeing
when trying to run ParaView?

				     $ paraview
				     ParaView error: InitializeTcl

				If so, then the TCL_LIBRARY environment

				hey again,

				so, to follow up on my previous email, i
have also tried to build paraview directly from the source code
(following the wiki's instructions and making the necessary adjustments
to ccmake options such as adding WI,-search_paths_first to the listed
linkers)

				the make of the program appears to work
fine

				afterwards, i try to run ./paraview
(from the /bin directory) and i get the same error messages as when i
was trying to run the pre-compiled binaries:

				    ParaView error: InitializeTcl failed

				    TK_Init error: no display name and
no $DISPLAY environment variable 

				very frustrating.....i could use some
help!!

				to all, 

				hi.  im trying to run ParaView 2.6 on an
intel mac pro running 10.4.  im VERY new to a unix environment, so
please bear with me. 

				after downloading the paraview 2.6 intel
precompiled binaries, i attempt to launch paraview from the console
(using ./paraview in the /bin directory). 

				i immediately get this message: 

				   ParaView error: InitializeTcl failed 
				   TK_Init error: no display name and no
$DISPLAY environment variable 

				i have tried running paraview on a
powerpc g4 and i got the exact same error message, so im pretty sure its
something really stupid that im messing up. 

				any suggestions??? 

				thanks, 
				jared
