I've looked into this.
Current test script picks msys2-compiled python, which, after your
modification, can't find 'windll', because msys2-compiled python is
cygwin-like and it's 'ctypes' has no 'windll'. If we rewrite the
relevant part of script thus:
config.msys2 = False
....
elif v.startswith("MINGW"):
config.msys2 = True
....
# Try to use UTF8
if windows:
import ctypes
if config.cygwin or config.msys2:
# Is this actually right? Which calling convention does it use?
# As of the time of writing, ctypes.windll doesn't exist in the
# cygwin python, anyway.
mydll = ctypes.cdll
else:
mydll = ctypes.windll
then we go slightly further and fail with:
Traceback (most recent call last):
File "../driver/runtests.py", line 151, in <module>
import ctypes
File "/usr/lib/python2.7/ctypes/__init__.py", line 451, in <module>
pythonapi = PyDLL("libpython%d.%d.dll" % _sys.version_info[:2])
File "/usr/lib/python2.7/ctypes/__init__.py", line 365, in __init__
self._handle = _dlopen(self._name, mode)
OSError: No such file or directory
And this is definitely a bug in msys2 python, because there is no such a
file ("libpython*.dll) anywhere in msys2 distribution.
What could be possible solutions?
1. I'm seeing a new version of Msys2 appearing right now here
http://sourceforge.net/projects/msys2/files/REPOS/MSYS2/i686/. It is now
a bunch of separate packages, I've looked into python 2.7.5 package and
found ctypes-related things definitely changed. Thus we could wait a
couple of days until Msys2 release process is finished and installation
information is available, hoping it's python is working properly.
2. Another approach is to modify testing infrastructure to use some pure
win32/mingw based python distribution. But I'm in no way an expert here,
sorry.
Cheers,

Austin, or others,
It would be SO GREAT if it was possible to validate on Windows again.
Currently I'm using msys2, which builds GHC fine, but things fail
badly in the testsuite.
Traceback (most recent call last):
File "../driver/runtests.py", line 144, in <module>
raise Exception("Can't detect Windows terminal type")
Exception: Can't detect Windows terminal type
uname --s returns MINGW_NT-6.2
Changing the test from
elif v.startswith("MINGW32"):
to
elif v.startswith("MINGW"):
just produces a new error
Traceback (most recent call last):
File "../driver/runtests.py", line 155, in <module>
mydll = ctypes.windll
AttributeError: 'module' object has no attribute 'windll'
../mk/test.mk:242: recipe for target 'test' failed
It's all very frustrating because I can't validate. Can anyone help?
