"Too much recursion" error with basic Haste use

Question

I'm trying to put together a little front-end application with haste, and I'm running into errors on Firefox. Here's the minimal example of the error:

My Haskell:

module Main where

import Haste

main :: IO ()
main = writeLog "Testing..."

My HTML:

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
  <head>
    <script type="text/javascript" src="Experimentascript.js"></script>
  </head>
  <body>
  </body>
</html>

My compilation output:

What am I doing wrong?

I know nothing, but did you see the resolution of https://github.com/valderman/haste-compiler/issues/33 ? Also, what version of Haste are you using? — dfeuer, Dec 10 '14 at 03:25
Wasn't aware of the issue, and don't really see how it's relevant. I'm using `haste` directly out of `cabal install`. `hastec --version` says `0.3`. — Inaimathi, Dec 10 '14 at 03:38

Looks like this was just an issue with the haste-compiler version I was running. To resolve it, I had to run

cabal update
cabal install haste-compiler
haste-boot

in that order. I'm now running hastec version 0.4.3, and no longer getting recursion errors. I did also have to re-install certain haste libraries with

haste-inst install <library-name>
