Sam,
PS It could of course also be something else: Is you src/Makevars for your test package correct? Did you use `RcppArmadillo.packages.skeleton()` ? You need the lapack/blas link instruction therein. See edd@rob:~$ cat /usr/local/lib/R/site-library/RcppArmadillo/skeleton/Makevars ## With R 3.1.0 or later, you can uncomment the following line to tell R to ## enable compilation with C++11 (where available) ## ## Also, OpenMP support in Armadillo prefers C++11 support. However, for wider ## availability of the package we do not yet enforce this here. It is however ## recommended for client packages to set it. ## ## And with R 3.4.0, and RcppArmadillo 0.7.960.*, we turn C++11 on as OpenMP ## support within Armadillo prefers / requires it CXX_STD = CXX11 PKG_CXXFLAGS = $(SHLIB_OPENMP_CXXFLAGS) PKG_LIBS = $(SHLIB_OPENMP_CXXFLAGS) $(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS) edd@rob:~$ Dirk -- https://dirk.eddelbuettel.com | @eddelbuettel | e...@debian.org _______________________________________________ R-SIG-Debian mailing list R-SIG-Debian@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-debian
