How to make an R package that uses Boost.Thread, qualified to be published on CRAN or shared by the most
Hi,
Recently, I made an R package that used the C++ library Boost.Thread (http://www.boost.org/doc/libs/1_54_0/doc/html/thread.html) for multithreading. Previously, I have posted a question at stackoverflow (http://stackoverflow.com/questions/19651954/is-it-possible-to-build-an-r-package-which-use-rcpp-and-boost-thread-on-http), and I also asked at rcpp-devel

minus I and minus L flags
I have been RTFM/doc/www, but I'm still lost.
How does one tell R CMD INSTALL and R CMD check (both) that libraries
are installed in non-usual places and so -I/APPS/include (or whatever)
is necessary in CPPFLAGS and -L/APPS/lib (similarly) is necessary
in LDFLAGS?
I know I can hardwire them in pkg/src/Makevars, but this requires hand
editing of that file by each installer (yuck!)

Rcpp with OpenMP - Need example Makevars
Dear R experts,
recently I started developing a Rcpp package "OpenMPTest".
Within that package I want to use OpenMP, as in the following code example:
// header file
#include <omp.h>
using namespace Rcpp ;
RcppExport SEXP testOpenMP( SEXP nThreads ) ;
// cpp file
SEXP testOpenMP( SEXP nThreads ) {
BEGIN_RCPP
NumericVector numberThreads = NumericVector( nThreads );

RMySQL install
I am having trouble installing RMySQL on a clean install of Fedora Core 4 64
bit on a dual dual core machine (that is, two dual core processors). Seems
like the LD_LIBRARY_PATH is incorrect, but I don't seem to have it quite
right yet.
There are a few mentions of this problem in google, but thus far none of the
"fixes" and fixed my problem. I've tried defining the

How to pass
HI!
Have somebody an expample how the syntax is for passing the path of
include files to:
"If a package needs to specify additional directories for search-
ing header les (`-I' options) or additional libraries for linking (`-l'
and `-L' options), it
should do this by setting the variables PKG_CPPFLAGS and PKG_LIBS in
`src/Makevars'." But no examples. :-(

Why is my R package still compiling with the O2 flag?
When I install an R package with cpp codes such as rrcov via CRAN (under
R 3.1.1, using no Makevars file and under Ubuntu 14.04 using GCC 4.8),
the cpp code is compiled with the -o3 flag (in fact, looking at the
Makeconf file this seem to again be the default since R 3.1.1) But when
I install my own package via CRAN it is compiled with the -o2 flag.
My questions are what is causing my

compile c++ code in an R package without -g
Hello,
I'm writing an R package that is mainly written in C++. By default, R
CMD INSTALL creates C/C++ flags as follows:
-g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat
-Werror=format-security -D_FORTIFY_SOURCE=2 -g
However, my package is fairly large. With debug info compiled into the
library, the generated .so file is over 200MB. Without debug info,
it's about 30MB. I hope

Rcpp, dyn.load and C++ problems
Hi,
I have written a small C++ function and compile it.
However in R I can't see the function I have defined in C++.
I have read some web-pages about Rcpp and C++ but it is a bit confusion
for me.
Anyway,
This is the C++-code:
#include <Rcpp.h>
using namespace Rcpp;
// [[Rcpp::export]]

Makevars PKG_LIBS ignored by SHLIB (PR#9473)
Full_Name: Rick Sayre
Version: 2.4.0
OS: Windows
Submission from: (NULL) (138.72.27.164)
PKG_LIBS works fine on *nix
on windows, it seems to be ignored by the "SHLIB" script
so, R CMD SHLIB blah
properly uses PKG_CPPFLAGS and PKG_CFLAGS from Makevars, but PKG_LIBS is
ignored

Installing package fails at "testing if installed package can be loaded from temporary location"
Dirk, thank you a thousand times.
Indeed, src/Makevars was wrong. I modified Makevars so that now looks like
the below and the package now compiled and linked properly.
CXX_STD = CXX11
PKG_LIBS += $(SHLIB_OPENMP_CXXFLAGS) $(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS)
$(shell ${R_HOME}/bin/Rscript -e "RcppParallel::RcppParallelLibs()")
