[R-SIG-Mac] installing rgl with the 3.0 RC

[Robert J Goedman]

Bryan,

I've seen that issue a couple of times as well. Trying to install rgl 0.93.934 from R-Forge using R.app, I get (in the R.app console):

...
mv AGL/* .
MAKINGAGL=TRUE /Library/Frameworks/R.framework/Resources/bin/R CMD SHLIB  -o aglrgl.so *.cpp *.c \
		osx/*.mm osx/*.cpp
mv: rename AGL/* to ./*: No such file or directory

osx/osxgui.mm:9:2: error: #error Cocoa backend reguires FreeType font reneder
make[1]: *** [osx/osxgui.o] Error 1
make: *** [aglrgl.so] Error 1

The downloaded source packages are in
	‘/private/var/folders/fl/jchvcqm92rd7bjh6hzkd1cqc0000gn/T/RtmpgyhrHG/downloaded_packages’
ERROR: compilation failed for package ‘rgl’
* removing ‘/Users/rob/Library/R/3.0/library/rgl’
* restoring previous ‘/Users/rob/Library/R/3.0/library/rgl’
>

On my system the following trick works. Make sure to keep a copy of the RGL package you want to install (typically the version is in the directory containing the downloaded packages, as printed at the end of the install process in the R.app console). Notice that these are removed if you quit R.app! So just keep R.app running.

I then use, in a terminal window:

cd /private/var/folders/fl/jchvcqm92rd7bjh6hzkd1cqc0000gn/T/RtmpgyhrHG/downloaded_packages
R_ARCH=/X86_64 R CMD INSTALL rgl_0.93.924.tar.gz

Towards the end of the build/install I get:

...
installing to /Users/rob/Library/R/3.0/library/rgl/libs/X86_64
** R
** demo
** inst
** preparing package for lazy loading
** help
*** installing help indices
** building package indices
** testing if installed package can be loaded
Warning in rgl.init(initValue) : RGL: unable to open X11 display
Warning in fun(libname, pkgname) : error in rgl_init

* DONE (rgl)

These last 2 warning messages only show up if XQuartz.app is not running. 

Testing in R.app:

library(rgl)
demo(rgl)

works (at least on my system!).

I'm appending right here in case there is something else you want to look at.  I restarted my computer but the result is the same.  I'm on OSX OS X 10.8.2 (12C60). Thanks, Bryan
