A second fix-up release is needed following on the recent bi-monthly RcppArmadillo release as well as the initial follow-up as it turns out that OS X / macOS is so darn special that it needs an entire separate treatment for OpenMP. Namely to turn it off entirely…
Armadillo is a powerful and expressive C++ template library for linear algebra aiming towards a good balance between speed and ease of use with a syntax deliberately close to a Matlab. RcppArmadillo integrates this library with the R environment and language–and is widely used by (currently) 384 other packages on CRAN—an increase of 54 since the CRAN release in June!
Changes in RcppArmadillo version 0.7.960.1.2 (2017-08-29)
On macOS, OpenMP support is now turned off (#170).
The package is now compiling under the C++11 standard (#170).
The vignette dependency is correctly set (James and Dirk in #168 and #169)
