I've just bought a new iMac with 10.5.4 of OS X. I installed R 2.7.1 on
it with no problems.
I tried to install Xcode 3.0, but three downloads (two Firefox, one
Safari) were corrupt, so I installed 3.1.
Now, the weirdness:
When I try to install rgl from the CRAN source, or from a local
directory using R CMD INSTALL, the configure script fails with these
messages:
checking for X... libraries /usr/X11/lib, headers /usr/X11/include
checking for glEnd in -lGL... no
configure: error: missing required library GL
ERROR: configuration failed for package 'rgl'
** Removing '/Library/Frameworks/R.framework/Resources/library/rgl'
** Restoring previous
'/Library/Frameworks/R.framework/Resources/library/rgl'
However, if I run the configure script (as ./configure) within the local
directory, it succeeds:
checking for X... libraries /usr/X11/lib, headers /usr/X11/include
checking for glEnd in -lGL... yes
I can then move the configure script out of the way and R CMD INSTALL
proceeds (until it gets to the FTVectoriser error, which I'm working on
fixing).
Why would R CMD INSTALL make the configure script fail???
