[Rcpp-devel] RInside under Windows

Tue Feb 14 21:55:23 CET 2012

My experience is that any odd error you get with Windows 7 is definitely
related to security.

Right-click the exe in Explorer and select Run as Administrator. Try to
start a Cygwin terminal as Administrator to do command line work
(assuming you are using Cygwin).

I have no choice but to run RStudio and R via Run as Administrator; they
just won't work otherwise. I set up shortcuts to do this and pinned them
to my toolbar. Ditto with Visual Studio.

This is Windows, remember -- perhaps there is a way of doing a diff, I
don't know it.  But the start of Makefile.win that I see out of the box
is:

n## -*- mode: makefile; tab-width: 8; -*- ## ## Simple Makefile for
Windows

Note the bizarre first character.

Agreed.  That is the only indication of it being upset.

But I renamed that file to try to make it do it last.
Running it again there was no error -- everything compiled.

Compiled for 32-bit.

There is not an x64 subdirectory to 'lib' (as there is with 'libs') so
nothing compiles.

That's an interesting idea.  Anyone have ideas about testing it?
