Hi,
In the README.txt of the numpy installation it says that one could use a
site.cfg file to
specify non-standard locations of ATLAS en LAPACK libraries, but it doesn't
explain how.
I have a directory software/atlas3.6.0/lib/Linux_PPROSSE2/ which contains
libcombinedlapack.a libatlas.a libcblas.a libf77blas.a liblapack.a
libtstatlas.a
where liblapack.a are the few lapack routines provided by ATLAS, and
libcombinedlapack.a
(> 5 MB) contains the full LAPACK library including the few optimized routines
of ATLAS.
>From the example in numpy/distutils/system_info.py I figured that my site.cfg
>file should
look like
--- site.cfg ---
[atlas]
library_dirs = /software/atlas3.6.0/lib/Linux_PPROSSE2/
atlas_libs = combinedlapack, f77blas, cblas, atlas
---------------
However, during numpy installation, he says:
FOUND:
libraries = ['combinedlapack', 'f77blas', 'cblas', 'atlas']
library_dirs = ['/software/atlas3.6.0/lib/Linux_PPROSSE2/']
which is good, but afterwards he also says:
Lapack library (from ATLAS) is probably incomplete:
size of /software/atlas3.6.0/lib/Linux_PPROSSE2/liblapack.a is 305k
(expected >4000k)
which he shouldn't use at all. Strangely enough, renaming libcombinedlapack.a
to liblapack.a
and adapting the site.cfg file accordingly still gives the same message.
Any pointers?
