R help - Jun 2004 - Building R as shared library (dll) in Windows

Hello,

I've read that to compile R as a shared library in Linux you have to issue
the following command before make:
./configure --enable-R-shlib

How is that done in Windows? There is no 'configure' in src/gnuwin32 and
if it has to go somewhere in Mkrules, I could not figure out exactly where.

Help please.

There are no `shared libraries' under Windows (and in fact
--enable-R-shlib builds a dynamic library rather than a shared library on
systems which care about the distinction).  However, it is the default to
build R as R.dll with import library libR.a.  You could try reading the
documentation, especially that on (D)COM interfaces to R, which make this
process easier.  However you can link your own code against R.dll, and
there are examples in src/gnuwin/front-ends (and a README file there).
