Re: [igraph] Error when loading the tkcl interface

[Gábor Csárdi]

Hi,

I am not sure what is XQuartz, but you don't need it at all. There is an X server in OSX, AFAIK, unless you are using a very old version. But the X server might not matter for the bug, anyway. 

What is your igraph version? R version? Output of sessionInfo()? OSX version? gcc version? Even with these, it seems hard to reproduce this bug, without these it is impossible.

Btw. if you just load the tcktk package with 'library(tcltk)', does that work?

Hello,

Maybe someone can help me.  I just switch to Mac, and I'm trying to use the "tkplot" function, but I get this error and message when the program tries to load the tcl/tk interface, and I cannot continue working, I have the XQuartz 2.7.4 (xorg-server 1.13.0), and the tcltk interface and additions on my package manager list.  I'm I missing something?

2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
