Reproducing this error is not easy. I was able to do so using docker with https://github.com/rocker-org/rocker-versioned/blob/master/r-ver/3.4.3/Dockerfile as starting point. If you remove lines 30 and 97 (openblas-dev and --with-blas), you can build a docker image with R included that uses the BLAS and LAPACK supplied by R. I have given this a try and installing 'cda' in such a image does indeed reproduce the error. Unfortunately adding 'arma::solve_opts::no_band' to the two places where arma::solve is used did not help in my tests :-( > The 'crippled Lapack' macro was useful as a workaround in the past but > I'm not sure of its exact mode of operation so I'm reluctant to set > something to "cripple" the code (does it target only those routines that > are found missing, or is it more of a blanket switch with no fine-tuning?). I think it is a blanket switch that will affect also those methods that where already added in the past. So this would be only a temporary solution, but I think that's what you need right now. BTW, setting ARMA_CRIPPLED_LAPACK is more difficult than I thought since it is #undefed in the RcppArmadillo-Config. Short of editing that file, you can add this to src/Makevars PKG_CXXFLAGS=-DARMA_CRIPPLED_LAPACK -DRcppArmadillo__RcppArmadilloConfigGenerated__h I hope there is a better way ...
