NumPy problem

Hello everyone,

after following the "official" guide to compiling numpy with mkl: Numpy user note
I still cannot use numpy. When I run:

[bash]python2.6 -c "import numpy;numpy.test()"
[/bash]

I get:

[python]Traceback (most recent call last):
  File "", line 1, in 
  File "/usr/local/cluster/scipy/mkl/lib/python2.6/site-packages/numpy/__init__.py", line 137, in 
    import add_newdocs
  File "/usr/local/cluster/scipy/mkl/lib/python2.6/site-packages/numpy/add_newdocs.py", line 9, in

    import multiarray
ImportError: /usr/local/cluster/scipy/mkl/lib/python2.6/site-packages/numpy/core/multiarray.so: undefined symbol: __intel_sse2_strlen[/python]

LD_LIBRARY_PATH and LD_RUN_PATH are set to the directories that contain composerxe-2011 compiler and mkl libraries (intel64).

What am I missing, what am I doing wrong?

Thanks in advance
Moritz

Hi,

While using ICC it needs to link additionally with libirc where __intel_* symbols are located. As an alternative there exists special compiler option (depending on compiler version) to not use such optimized functions.
