[Rd] Problem with compiling OpenBLAS to work with R

[Erin Hodgess]

Hello!

I'm not sure if this is the right place to post this, so apologies
in advance if I'm not in the right list.

I downloaded the OpenBLAS and am following Avraham Adler's great
instructions.  However, when I run make, things go well to a certain point,
and then go bad:

make

touch cygopenblas_haswellp-r0.3.5.a
make -j 1 -C test all

I think it has something to do with the threads/pthreads but am not sure
how to fix it.  Any suggestions much appreciated.

Thanks,
Sincerely,
Erin
