I attempted to compile the simplest program written by Dirk:

#include <RInside.h>                    // for the embedded R via RInside

int main(int argc, char *argv[]) {

    RInside R(argc, argv);              // create an embedded R instance

    R["txt"] = "Hello, world!\n";   // assign a char* (string) to 'txt'

    R.parseEvalQ("cat(txt)");           // eval the init string, ignoring any returns

    exit(0);
}

The environment variable PATH in all contains this:
%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\R\batchfiles_0.6-6;C:\R\Rtools\bin;C:\R\Rtools\MinGW\bin;C:\Program Files\GnuWin32;C:\"Program Files"\R\R-2.15.1\;

I copied this Makefile from a existing R example of RInside in Windows XP.

## -*- mode: make; tab-width: 8; -*-

## Simple Makefile

## TODO: 
##  proper configure for non-Debian file locations,   [ Done ]
##  allow RHOME to be set for non-default R etc

## comment this out if you need a different version of R, 
## and set set R_HOME accordingly as an environment variable
R_HOME :=       C:\"Program Files"\R\R-2.15.1\

sources :=      $(wildcard *.cpp)
programs :=         $(sources:.cpp=)


## include headers and libraries for R

RBLAS :=        $(shell $(R_HOME)/bin/R CMD config BLAS_LIBS)
RLAPACK :=      $(shell $(R_HOME)/bin/R CMD config LAPACK_LIBS)

## if you need to set an rpath to R itself, also uncomment
#RRPATH :=      -Wl,-rpath,$(R_HOME)/lib

## compiler etc settings used in default make rules

LDLIBS :=       $(RLDFLAGS) $(RRPATH) $(RBLAS) $(RLAPACK) $(RCPPLIBS) $(RINSIDELIBS)

all:            $(programs)
            @test -x /usr/bin/strip && strip $^

run:            $(programs)
            @for p in $(programs); do echo; echo "Running $$p:"; ./$$p; done

This is my R folder in C drive:

I saw this thread but I don't have anything like site-library in the R folder.

I changed the R_HOME to C:\"Program Files"\R\R-2.15.1, that resulted in the following errors:

Answer 1

It fails because you installed R in C:\Program Files\R even though the FAQ for R on Windows tells you not to install R in a path with spaces. See "Question 2.2: How do I install R for Windows":

If you want to be able to build packages from sources, we recommend that you choose an installation path not containing spaces.

The Rcpp / RInside documentaion repeats that recommendation. Do not install R in a path with spaces. If you must, you have to fix the Makefile to avoid the path expansion from breaking.

Answer 2

Your path are totally wrong for me: why you use C:\R\Rtools\bin as R_HOME if your R main path is simply C:\R ? If your R folder is what you've shown in the screenshot, BTW, also your classpath is totally wrong!
