Hi -

I'm just starting out, trying to use Elm on Windows 7 64-bit, Haskell Platform 2012.4.0.0. I have not been able to get Elm running. I have tried two different approaches ("compile.bat", and "cabal install elm-yesod") detailed below:

(1) "compile.bat" gives error: Could not find module 'Happstack.Server.Compression'

After downloading elm, unzipping and moving it to c:\www\elm000, attempting to run compile.bat on Windows 7 gives the error: "Could not find module 'Happstack.Server.Compression'":

(2) "cabal install elm-yesod" gives error: unable to load package 'regex-pcre-builtin-0.94.4.5.8.31'

Now I attempt a different approach. I already have yesod-platform installed. So I think maybe elm will work using the server provided with Yesod - if the server provided with elm can't be compiled. But this approach gives the error: "unable to load package 'regex-pcre-builtin-0.94.4.5.8.31'":

I have heard previous reports of problems involving cabal and package dependencies. I hope someone can figure out how to resolve the problems which are preventing using elm on this Windows 7 system.

By the way, I also have run 'cabal update' and re-attempted the above commands, and it produces the same errors.

Below is a listing of the haskell packages installed by cabal on my system. (Sorry for the lengthy list, but I thought it might help diagnose where there may be missing or conflicting packages).

Sorry for the long delay. I did not understand what was going wrong. It appears that elm-yesod has not been maintained for a long time. To install Elm, the best route is cabal update ; cabal install Elm

I'm going to close this issue which seems very specific. If you have issues with the recommended installation process from the website and the README in the github repo, please open an issue on that (with less print out :P)

Hi Evan -

No problem with the long delay - I've actually been sidetracked with other stuff myself.

I really wanted to congratulate you on this monumental achievement of developing the Elm language.

As a person with more background in theoretical computer science (eg, executable algebraic specification languages such as Maude) I have been quite frustrated for the past 15 years ago trying to understand the hundreds of web programming approaches out there, and your approach with Elm is refreshingly rigorous and expressive - somewhat similar to other approaches such as UrWeb and Yesod.

I hope you manage to keep the Elm project alive, and perhaps attract some additional people to help out with it. I would imagine that people from the world of functional, formal, algebraic languages (with some background as to what HTML and JavaScript do) might be able to help out quite a bit.

Best regards!
