I am really out of my element on windows, but I know there is a cygwin
package for libming.
My question is, does anyone have advice/examples on linking R packages
against cygwin libraries? Is this even possible? How would I go
about writing a configure.win script to do this?
I suspect it's not going to work. Linking to any Cygwin library will
pull in the rest, and I would guess that will conflict with something
else in R, which does not use Cygwin.
What you could do is include a copy of the source to the ming library,
and get the regular R compilers to compile it. I just tried, and it
compiled without errors (though there were a few warnings). Then you
can write your R interface to it, and everything may just work.
The tricky bit might be getting the Makevars or Makefile right, but
theirs is really simple, so that shouldn't be so bad.
