[Rcpp-devel] RcppArmadillo error

[Abhisek]

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

abhisek at 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!
