Interesting question. The whole 'R and C++11' nexus is a little toxic (as the
CRAN gatekeepers exists on the older standard; some of us are working behind
the scenes to change that). By and large, using -std=c++11 should not bite.
We use it for a things with Rcpp, but because we cannot (yet!!) upload to
CRAN with it, there isn't as much testing for C++11.
R itself is in C and does not care. Boost may care (and Boost 2.0 will be
guaranteed to work this way). No idea about Swig. I haven't built the QL-Swig
bindings in a while.
Now, your post doesn't actually show the error. What happens when you simply
set appropriate CXXFLAGS as in
CXXFLAGS= -g -O3 -Wall -pipe -Wno-unused -pedantic -std=c++11
(I usually do that in ~/.R/Makevars; you can also set it per package in
src/Makevars).
Can you try and report back?
Dirk
