Hi Johan,
did you resolve this? If not, make sure `-m64` and `-DMS_WIN64` are in
the gcc compiler options. I just tried: rpy2-2.3.x (from hg) builds
without errors using Rtools216.
Unfortunately the 64 bit extension often (not always, with no apparent
pattern) fails to load when repeatedly running `python -c"import
rpy2.rinterface"`:
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "X:\Python27-x64\lib\site-packages\rpy2\rinterface\__init__.py",
line 93, in <module>
from rpy2.rinterface._rinterface import *
ImportError: DLL load failed: A dynamic link library (DLL)
initialization routine failed.
The installers are at <http://www.lfd.uci.edu/~gohlke/pythonlibs/#rpy2>
if anyone wants to try.
