Below is what I added to the Rcpp-FAQ. The pdf will come out with the next
revision of Rcpp.
Hope this helps, Dirk
1.2 What do I need ?
Obviously, R must be installed. Rcpp provides a C++ API as an extension to
the R system. As such, it is bound by the choices made by R and is also
influenced by how R is configured. In general, the standard environment for
building a CRAN package from source (even when it contains C or C++ code) is
required. This means one needs:
* a development environment with a suitable compiler (see below), header
files and required libraries;
* R should be built in a way that permits linking and possibly embedding of
R; this is typically ensured by the -enable-shared-lib option;
* standard development tools such as make etc.
1.3 What compiler can I use?
On almost all platforms, the GNU Compiler Collection (or gcc, which is also
the name of its C language compiler) has to be used along with the
corresponding g++ compiler for the C++ language. A minimal suitable version
is a final 4.2.* release; earlier 4.2.* were lacking some C++
features. Generally speaking, and as of early 2011, the default compilers on
all the common platforms are suitable.
Specific per-platform notes:
Windows users need the Rtools package from the site maintained by Duncan
Murdoch which contains all the required tools in a single package;
complete instructions specific to Windows are in the ‘R Administration’
manual (R Development Core Team, 2010a, Appendix D).
OS X users, as noted in the ‘R Administration’ manual (R Development Core
Team, 2010a, Appendix C.4), need to install the Apple Developer Tools
(e.g., Xcode) (as well as gfortran if R or Fortran-using packages
are to be built).
Linux user need to install the standard developement packages. Some
distributions provide helper packages which pull in all the required
packages; the r-base-dev package on Debian and Ubuntu is an example.
