Scipy site.cfg adjusted again, and started a build – with the same result: numpy fails, so redone what I did before: all swithed off except LAPACK and BLAS:
Export BLAS=/home/wgrooters/ETW/lapack-release-lapack-3.8.0; export LAPACK=/home/wgrooters/ETW/lapack-release-lapack-3.8.0; ATLAS=None; export BLAS_SRC=/home/wgrooters/ETW/lapack-release-lapack-3.8.0/BLAS; export LAPACK_SRC=/home/wgrooters/ETW/lapack-release-lapack-3.8.0/SRC; python setup.py build;
Or use openBLAS?
export BLAS=/home/wgrooters/ETW/xianyti-OpenBLAS-15cb124; export LAPACK=/home/wgrooters/ETW/xianyti-OpenBLAS-15cb124; ATLAS=None; export BLAS_SRC=/home/wgrooters/ETW/xianyti-OpenBLAS-15cb124/lapack-netlib/BLAS; export LAPACK_SRC=/home/wgrooters/ETW/ xianyti-OpenBLAS-15cb124/lapack-netlib/SRC; python setup.py build;
Sources are found this time, but not the libraries. Of course, I should specify the correct locations:
export BLAS=/home/wgrooters/ETW/xianyi-OpenBLAS-15cb124; export LAPACK=/home/wgrooters/ETW/xianyi-OpenBLAS-15cb124/; export ATLAS=None; export BLAS_SRC=/home/wgrooters/ETW/xianyi-OpenBLAS-15cb124/lapack-netlib/BLAS/SRC; export LAPACK_SRC=/home/wgrooters/ETW/xianyi-OpenBLAS-15cb124/lapack-netlib/SRC
because the sources are on e deeper level (/SRC). That has a better result on config command:
/usr/lib64/python2.7/site-packages/numpy/distutils/system_info.py:491: UserWarning:
Blas (http://www.netlib.org/blas/) libraries not found.
Directories to search for the libraries can be specified in the
numpy/distutils/site.cfg file (section [blas]) or by setting
the BLAS environment variable.

but there seems to be more to exclude:

added. Didn’t help.
Should I put a question on a SciPy forum?
Changed the name of the OpenBlas directory – it contained quite a lot of extra naming that has no meaning here, but that didn’t solve the problem, all is put into one library. So I built the separate LAPACK and BLAS libraries using the MakeFile:
make clean
make lapacklib
make blaslib
but that didn’t give the intended result: There is a library liblapack-sandybridge.0.3.6 containing the objects of both LAPACK and BLAS. Not what I wanted: separate libraries.
Searched the Internet and found a description on how to build numpy using BLAS and LAPCK: http://www.tfinley.net/notes/blas-lapack/ . Published in 2007, but it may help.
