Open neuronphysics opened 6 years ago

I have installed scalapack already in my machine at this address # export SCALAPACK=/usr/local/scalapack/libscalapack.a # but when I tried to install scalapy I got the following error message:

gcc -pthread -shared -B /home/anaconda2/compiler_compat -L/home/anaconda2/lib -Wl,-rpath=/home/anaconda2/lib -Wl,--no-as-needed -Wl,--sysroot=/ build/temp.linux-x86_64-2.7/scalapy/blacs.o -L/usr/lib/gcc/x86_64-linux-gnu/5 -L/home/anaconda2/lib -lscalapack -lgfortran -lpython2.7 -o build/lib.linux-x86_64-2.7/scalapy/blacs.so -pthread -Wl,-rpath -Wl,/home/.openmpi/lib -Wl,--enable-new-dtags -L/home/.openmpi/lib -lmpi

How should I fix this issue in order to be able to install this package in my machine?

You need to point the compiler to the directory where scalapack is. It is probably sufficient to set the environment variable LIBRARY_PATH=/usr/local/scalapack/ before running setup.py if you are building against a static library (as it looks like you are). If you build against a dynamic library you may need to additionally set LD_LIBRARY_PATH before running as you have scalapack in a location that the linker won't search by default.

When I install scalapy, I get the following, Python 3.9.12 (main, Apr 5 2022, 01:52:34) [Clang 12.0.0 ] :: Anaconda, Inc. on darwin Type "help", "copyright", "credits" or "license" for more information.

import scalapy Traceback (most recent call last): File "", line 1, in File "/Users/dgrin/scalapy/scalapy/init.py", line 12, in from .core import * File "/Users/dgrin/scalapy/scalapy/core.py", line 43, in from . import blacs ImportError: cannot import name 'blacs' from partially initialized module 'scalapy' (most likely due to a circular import) (/Users/dgrin/scalapy/scalapy/init.py)

openblas and salapack are all installed. any thoughts?
