Re: [R-SIG-Mac] Unable to use vecLib BLAS and LAPACK in Mac OS 11.0.1
Dear Prof. Ripley, You are correct. I am using Xcode 12.2. Adding -Wno-implicit-function-declaration enabled the use of the Accelerate (vecLib) BLAS library. The issue is now resolved on on my system. Thank you! Best, Anirban > On 22 Nov 2020, at 2:24 PM, Prof Brian Ripley wrote: > > Which version of Xcode/Command Line Tools are you using?

Re: [R-SIG-Mac] Unable to use vecLib BLAS and LAPACK in Mac OS 11.0.1
Which version of Xcode/Command Line Tools are you using? If >= 12 (and perhaps earlier) Apple have set default C options which violate the C99/C11 standard, so you need -Wno-implicit-function-declaration. If you have a configure issue, do read and report the relevant parts of config.log file: it probably told you what the problem was (it did for me): conftest.c:227:1: error: implicit declaration of function 'dgemm_' is invalid in C99 [-Werror,-Wimplicit-function-declaration] We will add a further comment to the R-admin manual, but Big Sur has been released for less than a week and a hint was already there On 22/11/2020 17:33, Anirban Mukherjee wrote: Hi, I am having trouble configuring R to use the vecLib BLAS and LAPACK libraries.

[R-SIG-Mac] Unable to use vecLib BLAS and LAPACK in Mac OS 11.0.1
Hi, I am having trouble configuring R to use the vecLib BLAS and LAPACK libraries. I am on Mac OS 11.0.1 and Xcode 12.2. I tried the following options: 1. I downloaded the R binary from CRAN. I tried to follow the instructions at https://cran.r-project.org/bin/macosx/RMacOSX-FAQ.html#Which-BLAS-is-used-and-how-can-it-be-changed_003f to switch the BLAS library. I do not see libRblas.vecLib.dylib in the folder so I cannot switch the BLAS library as given in the FAQ. I also cannot locate libRblas.vecLib.dylib on my system. 2. I tried to compile R from source. I used the following configuration options: --with-blas="-framework Accelerate” and --with-lapack. I should have all requisite libraries. The compiled R does not use the vecLib BLAS and LAPACK (sessionInfo below signature). During configure, I noticed configure outputted: checking for dgemm_ in -framework Accelerate… no Is that perhaps why configure does not configure the compiled R to use the Accelerate (vecLib) framework?
