osx-arm64 builds do not link against `libblas`, `liblapack` #59

Open mfansler opened 1 year ago

mfansler commented 1 year ago

Examining recent build logs reveals that -lblas -llapack ends up linking to lib/R/lib/libRblas.dylib and lib/R/lib/libRlapack.dylib for osx-arm64 builds. This seems undesirable and makes the dependencies of libblas and liblapack superfluous for these builds.

I'll also note that I'm looking at this in relation to some unsolvable R 4.3 migrations that appear to have r-rcpparmadillo in the build requirements in common, specifically for osx-arm64 builds. However, this is still speculative (I don't see a reason why this would lead to unsolvability).
