[Numpy-discussion] numpy build issue on i7-2600K CPU

[Christoph Gohlke]

Hello,

building numpy 1.6.1rc2 on Windows, i7-2600K CPU, with msvc9 failed with 
the following error:

File "numpy/core/setup_common.py", line 271, in long_double_representation
     raise ValueError("Could not lock sequences (%s)" % saw)
ValueError: Could not lock sequences (None)


This problem has been mentioned before at 
<http://mail.scipy.org/pipermail/numpy-discussion/2011-March/055571.html>.


Opening the configtest.obj file in binary mode fixed the issue for me. A 
patch is attached.

Christoph
