I recently built NumPy & SciPy from svn sources using Intel's icc 10.0, ifort 10.0, and mkl 9.1 under openSUSE 10.2. In the process, I discovered and worked around four bugs (they are just quick hacks, not proper fixes; for example, some of them break compatibilty with earlier versions of Intel compilers and MKL) in NumPy svn 3868 distutils.

Bug#1: distutils/system_info.py contains the lines:

else: lapack_libs = self.get_libs('lapack_libs',['mkl_lapack32','mkl_lapack64'])

This will fail when MKL 9.1 is used because Intel changed the names of both 'mkl_lapack32' and 'mkl_lapack64' to 'mkl_lapack'. My work-around was to change the line to:

lapack_libs = self.get_libs('lapack_libs',['mkl_lapack'])

Bug#2: distutils/fcompiler/intel.py has several lines like this:

'version_cmd' : ['<F77>', None],

A work-around posted by George Nurser is to change all such lines to: (may break on Visual compilers)

'version_cmd' : ['<F77>', '-V'],

Bug#3: distutils/ccompiler.py has the line:

compiler_class['intel'] = ('intelccompiler','IntelCCompiler', "Intel C Compiler for 32-bit applications")

Unfortunately, in 10.0 Intel changed the result of icc -V to:

Intel(R) C Compiler for applications running on IA-32, Version 10.0 Build 20070426 Package ID: l_cc_p_10.0.023 Copyright (C) 1985-2007 Intel Corporation. All rights reserved. FOR NON-COMMERCIAL USE ONLY

My work-around was to change the above to:

compiler_class['intel'] = ('intelccompiler','IntelCCompiler', "Intel(R) C Compiler for applications running on IA-32")

Bug#4: distutils/fcompiler/intel.py has the same id string problem that ccompiler.py had. ifort -V returns:

Intel(R) Fortran Compiler for applications running on IA-32, Version 10.0 Build 20070426 Package ID: l_fc_p_10.0.023

I changed

version_match = intel_version_match('32-bit')

to

version_match = intel_version_match('IA-32')

#5 This is not a bug, but it's important to change distutils/intelccompiler.py from

cc_exe = 'icc'

to match the flags for your processor. For my Core 2 Duo, the line below works:

cc_exe = 'icc -g -fomit-frame-pointer -xT -fast'

After these changes, NumPy and SciPy built successfully, but scipy.test() returns a number of errors. The error reports are on the SciPy-dev list at the end of the thread: "Compiling scipy with Intel ifort & MKL"

Perhaps this will help someone...
