R devel - Dec 2020 - On Windows, need external access to the BLAS, LAPACK and LINPACK linear algebra functions included in R

Hi,

For my use, outside of the R environment, I am trying access the
BLAS, LAPACK and LINPACK linear algebra functions included in R

I am following the instructions here . . .

6.17 Using these functions in your own C code
https://cran.r-project.org/doc/manuals/r-release/R-exts.html#Standalone-Mathlib
AND
9.1 Unix-alike
https://cran.r-project.org/doc/manuals/R-admin.html#Unix_002dalike-standalone

to get . . .

6.7 Numerical analysis subroutines
https://cran.r-project.org/doc/manuals/r-release/R-exts.html#Numerical-analysis-subroutines

However, when I run configure, I (eventually) get this error, and configure
stops . . .

```
ComputerUser at COMPUTER MINGW64 /c/APPLICATIONS/r-source-R-4-0-branch
$ ./configure --with-x=no

checking for BSD networking... configure: error: BSD networking functions are
required
```

What do I need to do next?

Thanks,
Andre Mikulec

MinGW64 seems to be not sufficiently Unix-alike for ./configure to
conclude that it has sockets API (WinSock header names and some type
definitions are different from its expectations). You seem to be on
Windows. What happens if you follow the Windows workflow from the next
section?

https://cran.r-project.org/doc/manuals/R-admin.html#Windows-standalone

Apologies if I'm missing some context, but it seems to me that the
Windows workflow is what's needed here.
