A new maintenance release of RcppEigen is now on CRAN, and will go to Debian shortly as usual. Eigen is a C++ template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms.
A very recent change in the development version of R (aka “r-devel”)
expanded the set of declared BLAS and LAPACK functions (and I tooted
approvingly about it as well). It turns out that the
xerbla() declaration there (which, as usual for R and as
discussed in Writing R Extensions, defines the new optional
character length entry for a char vector) conflicts with one in the
blas.h header in Eigen upsetting the compilation
of just one reverse-dependency. So CRAN, as they so often (and
quietly) do in these cases, gave us a friendly and concise heads-up and
asked for a change so we complied, did the usual reverse-dependency
check of the other 400+ packages using RcppEigen and
produced the new release which was injected into the repository during
the current summer break.
The complete NEWS file entry follows.
