We do not currently build the MozEmbed package on Windows though it
might be possible to do so. 

In fact, I just checked and it is not at all clear that GtkMozEmbed
compiles on Win32 in any released version of Mozilla. See this bug:


It looks like at the moment you'd have to compile mozilla from source.
Some people seem to have be working on it and it might make it into
mozilla 1.8.

My first guess is that you have another version of iconv.dll on your
PATH that is being picked up but it is an older version or something.

Try searching your whole disk for "iconv.dll".

BTW which version of Gtk+ did you install exactly? which _rc number?


Are there any Win32 experts on these lists who know if there is a more
reliable way of matching up dlls to programs so that they always get the
right versions?

If one is distributing a single application you can stick the dlls into
the same directory as the .exe but obviously for a Haskell library our
users will be putting .exe files in any old directory and expecting them
to work.
