    1.111 was released yesterday, so you can update from the update site.

    Han Joosten - 2010-06-12

    Hi, I missed your last message for some reason. So I only saw it today. Sorry for that.
    I tried to update to release 1.111, but I got all sorts of errors. So I started all over again with eclipse.
    I downloaded the plugin developement eclipse version again and installed it. Then I updated the 1.111 version of http://eclipsefp.sf.net/updates
    Then I got a warning that no valid haskell implementation was found. (ghc is in my path, and could be found pretty easili, I guess. It is in the default location at C:\Program Files\Haskell Platform\2010.1.0.0\bin )
    So I added a haskell implementation.
    Now it is time to get "Hello World" up and running.:
    I create a new haskell project, and edit the src/Main.hs
    However, I do nog get anything to work with ghc. (ghci does work however). I had a look at the error log. This shows that there are problems starting the scion server. I removed my previous one, expecting it to be part of eclipsefp 1.111.  Should I still build scion myself?

    The log shows this:

    Oops. I feel stupid. I missed the first error messag. It turned out that I had a wrong proxy setting for IE downloads….
    However, I still have trouble installing 1.111. More on that at the post of xenoblitz on installing 1.111
