Installing rgl - error: X11 not found but required, configure aborted

Hi Ezhil,

Dear All,

I am trying to install rgl from the source file: rgl_0. I tried
using: /usr/bin/R64 CMD INSTALL rgl_0.92.798.tar.gz and get the following
error message:

checking for X... no
configure: error: X11 not found but required, configure aborted.
ERROR: configuration failed for package ?rgl?
* removing
?/Library/Frameworks/R.framework/Versions/2.14/Resources/library/rgl?
* restoring previous
?/Library/Frameworks/R.framework/Versions/2.14/Resources/library/rgl?

I do see a directory X11 installed under /usr. Do I need to instruct rgl to
look for /usr/X11/bin? If so, how do I do that?

Check if you have X11.app in /Applications/Utilities

Also, when you get that sorted out, I think I needed to follow the
instructions here:
http://danbri.org/words/2011/12/08/761

in order to install rgl from source, namely you'd do:

R CMD INSTALL rgl_0.92.798.tar.gz ?configure-args=??disable-carbon? rgl

But, if you're not running R-devel, why not just install the prebuilt
package using `install.packages`?

(pretty sure that you'd still need to ensure X11 is installed, though)

Hi Ezhil,

Thanks a lot, Steve. I don't see X11.app in?/Applications/Utilities. I did
install xcode and X11 is there under /usr/X11. I will check the mac support
group site for this. Any suggestions to keep X11.app
under?/Applications/Utilities?

I'm not well versed in how to check if X11 is properly installed, but
the fact that you don't see it under /Applications/Utilities/X11.app
seems weird to me.

I'm also not sure if it's installed by default just by installing
XCode (I reckon Simon will chime in soon).

I don't think you mentioned what version of OS X you are running, did you?

Anyway, I'm not sure what's gong on, but if I were you I think I'd try
to (re?)install X11 and try again.

I know that you can install X11 from your system install disks -- at
one point in time, you would find this under some "Optional Installs"
something on the system install disk, not sure where it is now.

Alternatively, I think you could also install X11 using the installer
here, if you like:

HTH,
