Hi all,

Does anyone have a howto or instruction list on how to build Ruby 1.8.x  
(preferably .6) under MinGW _with_ binary extensions e.g. Zlib and  
OpenSSL?

I can’t find any docs/articles on that and the one from [ruby-lang.org](http://ruby-lang.org) is  
somewhat broken (complains of fcntl() not being implemented).

When I try to build it with a ./configure ; make ; make install, the  
ruby interpreter builds fine, but zlib, openssl, etc. do not build  
binaries for use with it (I have MinGW/MSYS installed already).

Any ideas? Thanks.

I got a little farther in the build (zlib, but no openssl still) but  
I’ve since stopped as the MinGW build of Ruby still exhibits the broken  
I/O behavior described here:

I will have to use Python or Perl for this. Oh well…
