Description Zhang Bo 2014-08-15 10:59:09 UTC
During installing process of scipy package, a log info may be reported like following:
libraries mkl_rt,iomp5,mkl_rt,iomp5 not found in ['/opt/intel/composerxe-2013.3.174/mkl/lib/intel64', '/opt/intel/composerxe-2013.3.174/compiler/lib/intel64', '/usr/lib64']
then a BlasNotFoundError will raise and cut off the installing.

Content of site.cfg:
include_dirs = /opt/intel/composerxe-2013.3.174/mkl/include
library_dirs = /opt/intel/composerxe-2013.3.174/mkl/lib/intel64:/opt/intel/composerxe-2013.3.174/compiler/lib/intel64:/usr/lib64
blas_libs = iomp5,mkl_rt
library_dirs = /opt/intel/composerxe-2013.3.174/mkl/lib/intel64:/opt/intel/composerxe-2013.3.174/compiler/lib/intel64:/usr/lib64
lapack_libs = iomp5,mkl_rt
Note that sections [blas] and [lapack] share the same libs and lib-dirs. The script, or the method get_libs() more precisely, parses this file and recognize there are 4 libs (rather than 2) to match, and then the method _check_libs() does the matching job and removes the duplicate results. The if condition in method _check_libs() is length comparing, namely if the amount of matched libs is not equal to amount of total libs, then matching fails. 

the core statement in get_libs() is 
libs = self.cp.get(self.section, key)
the parsing result "libs" can be fault.

386269 and 502406 might due to the problem above. I think this is the bug in numpy rather than scipy.

Reproducible: Always
Comment 1 Zhang Bo 2014-08-15 11:10:08 UTC
I've added a few codes in (did it to every python slot) and fixed this problem temporarily, but it's just a risky way.
Comment 2 Benda Xu gentoo-dev 2020-04-27 10:20:08 UTC
This is fix by the new ldso switching framework.
