rdiscount is a new Markdown library we just switched to, replacing
(the very slow) BlueCloth. It builds from C source, though, so I
wouldn't be surprised if Windows users have some trouble. (Catching
stuff like this is why we have edge Insoshi.) As far as the crypto
library goes, I don't know. Has anyone had these same troubles?

Maybe try running the installation under Cygwin and seeing how that goes.

I'm trying to set up a fork of Insoshi on Cygwin and ran into the same
problem - rdiscount won't install.

[Long Ouyang]

Sorry for replying twice - I didn't have the foresight to check the
install logs at first. I think the root of the issue is that gem
install can't find funopen() and fopencookie() (cf.
http://github.com/rtomayko/rdiscount/commit/07d325a6a494eb371c49e4264aa2db411d1d7d8a).

However, funopen() and fopencookie() exist in /usr/include/newlib.h
within my Cygwin installation - I'm at a loss as to how to tell "gem
install" to find it.

How did you do the rubygems install? If it's out of the context of cygwin then it might not know how to set the proper include/library directories.  (Although locations such as /usr/lib and /usr/include are fairly standard and are pretty much set by default by the compiler/linker.)

Also, take a look at the gem directory for the config/make files to see what compiler it's using.  If you have any Microsoft compilers (Visual C++ or the C/C++ dev kit), it might be picking those up instead of what you're expecting.

We removed the RDiscount dependency in edge a while back; I've just
pushed out a merge with master, so do a pull from GitHub and this
problem should go away.
