Why does my Tk application error out with "unknown color name white"?

Question

I just installed tkdiff on a ubuntu machine and when I try and run the program I get the following error:

 actual font: -family {DejaVu Sans Mono} -size -12 -weight normal -slant roman -underline 0 -overstrike 0
Error in startup script: unknown color name "white"
    (processing "-foreground" option)
    invoked from within
"text $w(LeftCB) -height 0 -padx 0 -highlightthickness 0 -wrap none  -foreground white -width 1 -borderwidth 0 -yscrollcommand  [list vscroll-sync "$w(..."
    (procedure "build-client" line 81)

Versions:

• Ubuntu 9.04
• tkdiff ??? (Could not find a version number)
• wish 8.5

Does anyone know how I should fix this? I could go into the tkdiff script and change white to a color value but that seems to me like I am fixing the symptom and not solving the real problem. In other words is there something wrong with my tkdiff or wish and the version of ubuntu?

Answer 1

Some Google research indicates that there might be a problem with the definition of "rgbpath" in your xorg.conf file (possibly in /etc/X11?). I'd either ensure that it's value is correct, or possibly remove the line all together.
