DetailsDescription:
Currently, updating openblas to 0.3.13 causes an error reported upstream here: https://github.com/xianyi/OpenBLAS/issues/3043. It happens due to lack of AVX support by old CPUs. Openblas should be built (as suggested by @brada4) with TARGET=core2 flag to support old CPUs without AVX instructions. Additional info: * package version: 0.3.13 * link to upstream bug report: https://github.com/xianyi/OpenBLAS/issues/3043 Steps to reproduce: 1. Update openblas to 0.3.13. 2. Run the following code in R (with an old CPU): ``` aa <- matrix(rnorm(50*10),ncol=10) B <- t(aa)%*%aa eigen(B) ``` |

Sorry, "core2" must be uppercase (TARGET=CORE2).
