Roland,
Sure, this code also compiles on my Linux box straight away, it also
compiles on my Windows box -- because everything is _already_ set up
there. The question was not whether the code was wrong -- such a "huge"
chunk of code could hardly be wrong and it was apparent it was written
just to try if one can _at all_ compile something for R. The question
was that something was missing to compile it and Tim did not specify
anything about his system except that it was Windows!
One might not need Cygwin if the code is like Tim's, i.e. has no
configuration whatsoever, that is right, but one in any case needs at
least MinGW (for gcc, visible in your output) and ActivePerl (for R CMD)
and RTools and R includes (visible in your output). You do have them
installed, does Tim also have them installed? If one adds a simple
config file (it will rather not work with a full UNIX-like configure)
then one might want to have Cygwin or MSYS as well.
Tim, when you get all those, add paths to <smth>\bin and <smth>\lib (as
there might be dlls and Windows searches for dlls in the PATH) to your
PATH. This includes R! One requirement: MinGW must be added in front of
Cygwin (for MinGW make) and RTools in front of both MinGW and Cygwin
(for all RTools to be used instead of those).
And the pdf file pointed to in my previous post was exactly written for
someone to start doing these things! It was written for Linux, but the
only difference on Windows is that you need those tools I mentioned above!
