> Does R just start up X11 or does it also show anything in it? Can you
strace the R execution and see where it executes X?
X11 just starts up. It doesn't seem to have any windows running. I don't
have strace installed on this computer, and I wouldn't know how to use it
if I did ;)
By the way, if I log into an OS X box remotely, I don't have this problem.
It must correctly detect that I can't run X11, and it also says that I
don't have 'png' capabilities.
kcrisman: Do you have X11 installed on your Mac? Maybe if it's not
installed, it doesn't go through this check and returns "FALSE" for png
capabilities.
I remember seeing something about compiling R with png support on
[http://ask.sagemath.org/], but I don't remember beyond that. I don't
think I have a particularly unusual setup, but who knows what R looks at?
In the install log for R, I see this:
{{{
Interfaces supported: X11, aqua, tcltk
External libraries: readline, ICU
Additional capabilities: PNG, JPEG, NLS
}}}
Anyway, I'm not suggesting unmerging the spkg, but fixing the doctest
somehow (in a followup ticket, if that's best). Can we do the equivalent
in Sage of
{{{
Sys.unsetenv("DISPLAY")
capabilities("png")
capabilities("aqua")
}}}
without breaking things on Linux or Solaris?
