Subject: how can I add the iconv extension to Ruby?

Hi everyonel,

I want to be able to convert UTF-16 strings to UTF-8.  From a usenet post I 
understand that the standard 'iconv' ext for Ruby can do that.  That same 
post explained that you have to:
1) install iconv (this step I thought I could skip since iconv came in the 
ruby-1.8.1.tar.gz)
2) set configure_args=--with-iconv-dir=<where_you_installed_it>
3) nmake

well, after doing so in the win32 directory for Ruby 1.8.1 I *do* see a 
message fly by saying "compiling iconv", but after it's done a search for 
iconv does NOT show either an iconv.so or an iconv.dll, and also nmake 
reports that ruby.exe and rubyw.exe have not been changed.

I also have a directory tree with ruby-1.9.0-20040402-i386-mswin32 which 
*does* contain an iconv.so file, but the version of irb in that directory 
tree apparently doesn't know where to look for the .so, just starting up the 
1.9.0.etc version of irb results in it showing a messagebox with the text: 
"This application has failed to start because readline.dll was not found. 
Re-installing the application may fix this problem." .  After clicking on 
the OK button irb does start running, but when I type require 'iconv' it 
gives that same messagebox, except that it says it can't find 'iconv.dll' 
and after clicking the OK button again I get to see the following lines in 
irb:
LoadError: 126: The specified module could not be found.   - 
H:/ruby_190/lib/ruby/1.9/i386-mswin32/iconv.so
        from H:/ruby_190/lib/ruby/1.9/i386-mswin32/iconv.so
        from (irb):1
And what's more, the iconv.so it says it can't find is exactly in the 
directory where irb says it can't find it!

So, my questions are: am I missing something really simple in that first 
procedure (the one for Ruby 1.8.1)? Or, alternatively, how can I get the 
Ruby 1.9 install to recognise that the .so files it can't find are exactly 
where it's looking?

Martin
