Build log attached.

I searched Trac but didn't find anything definitive.

I have the latest libtool and cctools installed.

build log

[jmroot (Joshua Root)]

The error actually appears to be:

:info:build blas00.c:6:5: error: implicit declaration of function 'dasum_' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
:info:build     F77_CALL(dasum)();
:info:build     ^

Well implicit function declaration strikes again.

Possible workarounds: blacklist Xcode clang, or use openmp variant (which will blacklist Xcode clang).

R @ 4.1.0 on Mojave with Xcode 11.3.1 still gives (on this OS with this Xcode):

Warning: Configuration logfiles contain indications of -Wimplicit-function-declaration; check that features were not accidentally disabled:

_NL_LOCALE_NAME: found in R-4.1.0/config.log objc_lookup_class: found in R-4.1.0/config.log objc_lookUpClass: found in R-4.1.0/config.log

Because it built successfully, there's no log, but it seems like the implicit function declarations haven't been dealt with yet.

Replying to LenoreHorner:
