Hello,
We are about to release RcppArmadillo 0.2.0 which works with Rcpp 0.8.0
and includes armadillo so all these issues should disappear.

i thought i would repost here as it is a similar problem:
i updated Rcpp and then RcppArmadillo and when i run : export
PKG_CXXFLAGS=`Rscript -e "RcppArmadillo:::CxxFlags()"`
i get the following error
abhi...@shieks:~/Desktop/Personal/Test$ export PKG_CXXFLAGS=`Rscript -e
"RcppArmadillo:::CxxFlags()"`
Error in dyn.load(file, DLLpath = DLLpath, ...) :
unable to load shared library
'/home/abhisek/R/i486-pc-linux-gnu-library/2.10/RcppArmadillo/libs/RcppArmadillo.so':
/home/abhisek/R/i486-pc-linux-gnu-library/2.10/RcppArmadillo/libs/RcppArmadillo.so:
undefined symbol: _ZN4arma12arma_version5majorE
Calls: ::: ... tryCatch -> tryCatchList -> tryCatchOne -> <Anonymous>
Execution halted
i tried recompiling RcppArmadillo, as well as uninstalling and
reinstalling RcppArmadillo from install.packages() to no avail.
could someone assist?
many thanks!

I ran into a similar error today after I upgraded my version of Rcpp
from 0.7.10 (or maybe 0.7.10.1) to 0.7.11:
/opt/R-2.10.1/lib/R/library/RcppArmadillo/libs/RcppArmadillo.so:
undefined symbol:
_ZN4Rcpp8internal12set_list_eltINS_5NamedEEEbP7SEXPRECS4_iRKT_
In my case, uninstalling RcppArmadillo and then installing it again
fixed
the error.
Maybe a new package version scheme is necessary to make it easier to
keep RcppArmadillo and Rcpp in sync? Would bumping up version numbers
more when there is a breaking API change help? For instance, when Named
was eliminated between 0.7.10 and 0.7.11, the new version could have
been called 0.8. RcppArmadillo packages would then depend on the Rccp
version being less than the next major API change.
