Hi Dan,
Currently the r-devel builds from CRAN still use the old tool
chain.
A
copy of r-devel which has been configured with the new tool
chain
is
available from
http://www.stat.ucla.edu/~jeroen/mingw-w64/R-experimental-r69418.exe
This build has BINPREF (the path to the compiler) hardcoded to
the
default location of the new tool chains. To change it you would
need
to edit this variable in C:\Program
Files\R\R-experimental\etc\x64\Makeconf and C:\Program
Files\R\R-experimental\etc\i386\Makeconf.
We are currently discussing how to design it such that you can
set
the
path to the compiler using an environment variable.
I ran the Bioconductor builds overnight using this toolchain
and
recent R-devel and did not notice anything odd with packages
containing native code, which means either the new toolchain
is
working perfectly (which is wonderful) or gcc-4.6.3 is still
being
used and maybe I need to do something to faciliate the use of
gcc-4.9.3. Can you advise?
We're talking to CRAN on how to coordinate the migration to the
new
tool chain. If you have bioc packages that link to external c++
libraries, those need a rebuild. The most current information is
available from: https://github.com/rwinlib/r-base#readme
