This is to summarize my workaround to install R/parallel in win32/64 boxes.
Recently I had problems to install rparallel:
1. The package's Makevars.win coded include fixed path for Rtools
2. package is written in C++; Rtools and R are not intended to run g++ by
default.
My workaround:
1. Need to install R, Rtools as usual. Note Rtools 2.12 has both 32bit mingw
and 64 bit. However, it doesn't include package for g++ and libstdc++. You
need to install these 2 packages into rtools from sourceforge first.
2. In rparallel source tree, open Makevars.win: change the PKG_CPPFLAGS and
PKG_LIBS variables to point to your correct rtools and rtools/mingw directories.
3. In R_installation/etc: open i386 or win64 (forget the name for 64bit) and
open Makeconf file; look for DLLFLAGS += ... and append -static-libstdc++.
This
flag will cause g++ to statically link in libstdc++.
then you can run usual R CMD INSTALL rparallel.
Good luck.
