问题


I am struggling to get F2PY working with Intel Fortran on Windows 7. This appears to be a common issue and I have attempted a number of suggestions found in other posts (described below).

A bit of information about my system:

  • Windows 7 64-bit
  • Python 2.7.11 via Enthought Canopy 32-bit (up to date as of June 12, 2016)
  • Intel Fortran 14 (Intel\Composer XE 2013 SP1) (32 and 64-bit)

After doing a bit of research see here I found that the issue may be related to the c++ runtime so I installed Microsoft Visual C++ for Python.

Still, when I attempt to build a simple test case, I receive the following error:

And here are some relevant system variables:

IFORT=C:\Program Files (x86)\Intel\Composer XE 2013 SP1\
IFORT_COMPILER14=C:\Program Files (x86)\Intel\Composer XE 2013 SP1\
INTEL_DEV_REDIST=C:\Program Files (x86)\Common Files\Intel\Shared Libraries\
INTEL_LICENSE_FILE=C:\Program Files (x86)\Common Files\Intel\Licenses

Path=C:\Users\mshippen\AppData\Local\Programs\Common\Microsoft\Visual C++ for Python\9.0\WinSDK\Bin; C:\Program Files (x86)\Intel\Composer XE 2013 SP1\bin\; etc …

Some things I have tried:

  • Ran ifortvars.bat as suggested here and here
  • Tried various --fcompiler = intelv, intelvem, intel, intelem options (even though intelv should be the correct one)
  • Added the [IFORT] system variable above as a duplicate of [IFORT_COMPILER14] in case F2PY stumbled on the version specific key
  • Tried extending these paths down a level to: C:\Program Files (x86)\Intel\Composer XE 2013 SP1\bin\ia32 (didnt work, so reverted back)

However, I get the same result. I am puzzled that despite my path and environment variable settings, the ifort.exe cannot be found. Any ideas or guidance would be much appreciated!

Thanks, Mack

After some further experimentation, I was able to resolve the issue and am posting the steps that worked in case it may help others with similar problems.

  1. f2py can now find Intel Fortran after setting the path to C:\Program Files (x86)\Intel\Composer XE 2013 SP1\bin\ia32 and rebooting

  2. However, after this, I received an error stating: "error unable to find vcvarsall.bat". This is the batch file with configuration settings for the Microsoft c++ for Python 2.7 runtime mentioned above. As I gathered from other posts, this is a bug in Python 2.7.11 that I was able to correct by editing the msvc9compiler.py file in the main (not numpy) distutils folder. Specifically, I hardcoded the path to this file as such in line 267:

    def query_vcvarsall(version, arch="x86"):
"""Launch vcvarsall.bat and read the settings from its environment  """
    vcvarsall = find_vcvarsall(version)
    vcvarsall =  "C:/Users/mshippen/AppData/Local/Programs/Common/Microsoft/Visual C++ for Python/9.0/vcvarsall.bat"
    interesting = set(("include", "lib", "libpath", "path"))
    result = {}
