An update to the announcement at
We now have daily builds of snapshots of R-devel for 64-bit Windows
available at http://cran.r-project.org/bin/windows64/contrib/ .
Tcl/Tk support is now provided.
There is a repository of binary packages available, selected by
options(pkgType="win64.binary"), at CRAN and CRANextras: currently we
can build about 2000 packages. The win-builder service has an option
to build and test packages under the current R-devel snapshot, and
logs of the builds for the repository are available as part of the
CRAN daily check at
http://cran.r-project.org/web/checks/check_summary.html (but note that
some of the failures are available on CRANextras). The default
remains to build packages from sources.
The main reason that packages have failed to build are unresolved
dependencies on either other R packages or external software.
Pre-built 64-bit DLLs of common Open Source libraries are much harder
to find than 32-bit ones and we have not put in the effort that we
have over the years for 32-bit Windows. Bioconductor binary packages
are not available (but that project has plans to build them in due
Package maintainers who ignored the advice not to write Makefiles (but
use Makevars) will find that chickens have come home to roost: such
packages almost certainly will not install. Including
and using macros such as $(CC), $(AR) and $(DLLTOOL) or (better) the
rules in Makeconf often does enable Makefile[.win] to be used.
