[Rcpp-devel] Seamless Rcpp gives errors with RcppArmadillo

Hi John,

Excellent, glad that worked out. In case you (or others on Mac) want to
play with C++11: http://gallery.rcpp.org/articles/first-steps-with-C++11/

R compiles with Clang. Clang has pretty complete support for C++11. The
older gcc 4.2.x compiler does not. But at this point you will have to
compile R from source if you want to go that route. Here is what I do:

svn co https://svn.r-project.org/R/branches/R-3-0-branch R-3.0.0
cd R-3.0.0
./tools/rsync-recommended
cd ..
arch=x86_64
mkdir R-$arch
cd R-$arch
export CFLAGS="-arch $arch"
export CXXFLAGS="-arch $arch"
export OBJCFLAGS="-arch $arch"
export FFLAGS="-arch $arch"
export FCFLAGS="-arch $arch"
./configure r_arch=$arch  CC="clang" CXX="clang" \
     F77="gfortran" FC="gfortran" OBJC="clang" \
     --x-includes=/opt/X11/include --x-libraries=/usr/X11/lib \
     --with-blas='-framework vecLib' --with-lapack
make -j12
sudo make install

There maybe some typos above as I edited by hand to change anything
specific to my machine. "Most" (in my usage, all) packages work with clang.
I have never had any issues (and I have been compiling R/Rcpp with Clang
for well over a year now). But of course YMMV.

Hope that helps.

Best,
Anirban
