Rcpp 0.10.1 was released yesterday (?). Installing it breaks RcppEigen and RcppArmadillo (same error message). Reinstalling the packages fixes RcppArmadillo, but not RcppEigen.
The error I get from compiling RcppEigen (version 0.3.1) is /hpscc/usr/local/gcc-4.1.2/install/R/R-devel/lib64/R/site-library/Rcpp/include/Rcpp/as.h:55: instantiated from ‘T Rcpp::internal::as(SEXPREC*, Rcpp::traits::r_type_generic_tag) [with T = Eigen::Map<Eigen::Matrix<double, -0x00000000000000001, 1, 0, -0x00000000000000001, 1>, 0, Eigen::Stride<0, 0> >]’ /hpscc/usr/local/gcc-4.1.2/install/R/R-devel/lib64/R/site-library/Rcpp/include/Rcpp/as.h:100: instantiated from ‘T Rcpp::as(SEXPREC*) [with T = Eigen::Map<Eigen::Matrix<double, -0x00000000000000001, 1, 0, -0x00000000000000001, 1>, 0, Eigen::Stride<0, 0> >]’ fastLm.cpp:208: instantiated from here ../inst/include/RcppEigenWrap.h:169: error: no matching function for call to ‘r_vector_start(SEXPREC*&)’ make: *** [fastLm.o] Error 1 ERROR: compilation failed for package ‘RcppEigen’ This translates to the following error when I load the already installed version of RcppEigen: > library(RcppEigen) Loading required package: Rcpp Loading required package: Matrix Loading required package: lattice Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared object '/hpscc/usr/local/gcc-4.1.2/install/R/R-devel/lib64/R/site-library/RcppEigen/libs/RcppEigen.so': /hpscc/usr/local/gcc-4.1.2/install/R/R-devel/lib64/R/site-library/RcppEigen/libs/RcppEigen.so: undefined symbol: _ZN4Rcpp8internal14r_vector_startILi10EiEEPT0_P7SEXPREC Error: package or namespace load failed for ‘RcppEigen’ I got the same error for RcppArmadillo (0.3.4.4) when doing library(RcppArmadillo), but this was fixed re-installing the package (unlike RcppEigen). This may be something you are aware of. I am mostly using RcppEigen through a chain of dependencies. I am on a fairly old system, with GCC 4.2.1 under Redhat Enterprise Linux version 4. This is for our cluster, so it is not easy for me to update.
