Normally, I do the following to configure R for compilation on my
Opteron box with ACML installed:
./configure --with-tcltk --with-blas="-L/opt/acml4.3.0/gfortran64/lib
-lacml"
However, when I do so, and look at Makeconf, I see
BLAS_LIBS = -lblas
I thought I would see
BLAS_LIBS = -L/opt/acml4.3.0/gfortran64/lib -lacml
Why isn't Makeconf picking up the right BLAS_LIBS (or is it? does -lblas
mean its finding the right blas?).
I tried
LD_LIBRARY_PATH=/opt/acml4.3.0/gfortran64/lib
export LD_LIBRARY_PATH
and then did a new Configure, but Makeconf still shows only
BLAS_LIBS = -lblas
When I look at config.log, I see a 'failure' that I think might be part
of the story:
configure:37157: result: no

So, perhaps things go awry at this point...weird thing is, thee is no
libgfortran.so.3 anywhere on the system that I can find....
