Trying to install python scrypt wrapper module in Windows 7 x64 and running into all kinds of problems.  Apparently nobody has been able to do it on x64 Windows, but a few have had success on win32 and just copied the site-package module folder over and that worked.  I was hoping some kind soul who has it working on Windows, x86 or x64, could upload their scrypt module folder for me, since the pure Python implementation of Scrypt (module "pyscrypt" if you're interested in testing) is about 300x slower than the C implementation wrapper....

I would like to formally protest the movement of this question to the alternate currencies sub.  The reason I want Scrypt is because I'm building a Bitcoin tools program and want to implement Bip38.  It is entirely related to Bitcoin specifically and NOT with any alt coins.  Additionally, I think the question is less likely to be answered in a less frequented sub.

Yet another reason why there should be a misc questions board....

Here you go: https://www.sendspace.com/file/0nhd8c

Make sure you have a 64 bit python installation or it won't work.

Would you mind reuploading that? Sendspace has removed the file.

Put it on a mega instead (shouldn't expire so quickly) https://mega.co.nz/#!eJd1TARD!IFHKj-xC1LfqLcym-j7KMChS6BzdOCBqMN2dcPYF06c

Here are some instructions to build it yourself:

First make sure you install the amd64 version of python, if you want a 64 bit build. The same process will work with python 32bit but will build a 32 bit module

Then just grab the p2pool repo;
https://github.com/forrestv/p2pool/archive/master.zip

extract it and enter the p2pool/litecoin_scrypt directory

Then to build your own enter the commands mentioned below in a windows command prompt

Set up the environment variables for the Visual studio 2010 build tools (note that it is different for 2012/2013; VS110COMNTOOLS for 2012 VS120COMNTOOLS for 2013)
Quote
SET VS90COMNTOOLS=%VS100COMNTOOLS%


then run

Quote
python setup.py install

and it should build and install a 64 bit version of the module for you.
