Hi, Sorry I never found the time to put this issue to rest. My cda package has now been removed from CRAN because Armadillo's update on 'banded matrices' broke it on various platforms, and I've had users enquire about the situation. As far as I can tell RcppArmadillo no longer enables the solution

Hi, Thanks for the pointer to `arma::solve_opts::no_band`, it sounds like a good solution (assuming the compiler will then skip all the parts related to banded inversion routines). I've been unable to test it so far; I haven't managed to reproduce the error reported on CRAN on a mac. The 'crippled

Re: [R-pkg-devel] Lapack: undefined symbol: zgbsv_

Thanks Dirk. I arrived at the same conclusions after tracking down the recent changes in Armadillo and noticing their addition of a special solve() case for banded matrices. What I don't really understand (because of the templating system etc.) is why this new routine in Armadillo would be needed a
