I found the following snippet in the NEWS file for R 2.14.1:
? R CMD INSTALL will now do a test load for all sub-architectures
for which code was compiled (rather than just the primary
This seems to have the following (unintended?) consequence:
Most of my machines are running some version of 64-bit Ubuntu and I do
not necessarily have all 32-bit libraries installed on these. In
particular, the 32-bit TCL/Tk libraries are frequently missing. Thus,
on such a machine the 32-bit sub-architecture of R does not have the
capability to use TCL/tk and the tcltk package is only installed for the
primary sub-architecture (64-bit).
Until now, I could always install the Rcmdr package on these machine.
However, this is no longer possible in 2.14.1. Now attempts to install
Rcmdr on such a machine ends with:
** testing if installed package can be loaded
*** arch - 32
Error : package 'tcltk' is not installed for 'arch2'
Error: loading failed
*** arch - 64
ERROR: loading failed for '32'
* removing '/home/opt/R/R-2.14.1/lib64/R/library/Rcmdr'
Is there a way of installing Rcmdr only for the 64-bit primary
sub-architecture? Or do I really have to install the 32-bit versions
of the TCL/Tk libraries and then reinstall R from scratch?
