[Rcpp-devel] Rcpp and inline, compiler configuration errors, windows 7

Thank you Dirk and Darren for your answers !

I edited the path to redirect it to C:\R\Rtools\gcc-4.6.3\bin (which comes
with Rtools) instead of C:\R\Rtools\MinGW\bin (which I had installed
manually). The examples now work ; I still have the cygwin warning but as
long as it doesn't affect the results it doesn't matter to me.

For the record, here is a summary of the different steps I went through to
run Rcpp and inline on Windows 7:
.R must be installed in a place that does NOT contain spaces (e.g.
C:\R\R-2.15.1)
.Rtools must be downloaded (from CRAN), and installed in a place that does
NOT contain spaces (e.g. C:\R\Rtools).
.The ?path variable? must be edited according to the recommendations of
the Appendix D of "R installation and administration"
-Either using the "path" command in the Windows Command Prompt
-Either using the RedmondPath software, which does the same thing in a
more user-friendly approach
.The packages Rcpp and inline must be downloaded and loaded into R

Useful tips can be found on:

Now I can begin coding the functions I need to use !

Thank you again for your fast and useful answers.

From what I understand of the error messages, g++ (the compiler, I
think) cannot be found. On this thread, someone had a problem that
looks like mine, it was a path problem :

http://lists.r-forge.r-project.org/pipermail/rcpp-devel/2012-March/003597.html

Their problem is distinct, in that g++ is being found ('cos it is g++
that gives their error message).
However note that their PATH contains:
C:\R\Rtools\gcc-4.6.3\bin

Whereas yours does not. So try adding that (but with the correct gcc
version for your system of course :-)
