I am trying to build numpy with intel icc and mkl. I don't understand
a lot of what I am doing. I have followed the the suggestions of what
to add/change in site.cfg intelccompiler.py and system_info.py from
several different posts or google searches. i am not sure i have done
any of this right. here are the contents of the files.
----------------------------------------------------------------------------------
site.cfg:
[DEFAULT]
library_dirs =
/opt/intel/mkl/10.0.3.020/lib/em64t,/usr/lib64,/usr/local/lib64,/usr/local/python2.5.2-intel/lib,/usr/lib,/usr/local/lib
include_dirs =
/opt/intel/mkl/10.0.3.020/include,/usr/include,/usr/local/include,/usr/local/python2.5.2-intel/include
[mkl]
include_dirs = /opt/intel/mkl/10.0.3.020/include
library_dirs = /opt/intel/mkl/10.0.3.020/lib/em64t
lapack_libs = mkl_lapack
[lapack_src]
libraries=mkl_lapack,mkl,guide
[lapack_info]
libraries=mkl_lapack,mkl,guide
-------------------------------------------------------------------------------
intelccompiler.py:
from distutils.unixccompiler import UnixCCompiler
from numpy.distutils.exec_command import find_executable
class IntelCCompiler(UnixCCompiler):
""" A modified Intel compiler compatible with an gcc built Python.
"""
compiler_type = 'intel'
cc_exe = 'icc -g -O3 -w -fPIC -parallel -ipo -xT -axT'
def __init__ (self, verbose=0, dry_run=0, force=0):
UnixCCompiler.__init__ (self, verbose,dry_run, force)
compiler = self.cc_exe
self.set_executables(compiler=compiler,
compiler_so=compiler,
compiler_cxx=compiler,
linker_exe=compiler,
linker_so=compiler + ' -shared')
class IntelItaniumCCompiler(IntelCCompiler):
compiler_type = 'intele'
# On Itanium, the Intel Compiler used to be called ecc, let's search for
# it (now it's also icc, so ecc is last in the search).
for cc_exe in map(find_executable,['icc','ecc']):
if cc_exe:
break
----------------------------------------------------------------
system_info.py:
....
class lapack_mkl_info(mkl_info):
def calc_info(self):
mkl = get_info('mkl')
if not mkl:
return
if sys.platform == 'win32':
lapack_libs = self.get_libs('lapack_libs',['mkl_lapack'])
else:
lapack_libs = self.get_libs('lapack_libs',['mkl_lapack'])
info = {'libraries': lapack_libs}
dict_append(info,**mkl)
self.set_info(**info)
...
------------------------------------------------------------------------
i then use this command to compile:
/usr/local/python2.5.2-intel/bin/python setup.py config
--compiler=intel config_fc --fcompiler=intel \
--opt='-fPIC -O3 -w -axT -xT' install > build.out
build.out has this in it:

it seems to compile and install fine.... then i start python and try
to run numpy.test(). that is where i am stuck. this is what happens:
# pwd

#
not sure how to get past this... although, I am sure, if numpy is not
working right then i will not be able to go on and compile scipy.....
Any help would be great....
