similar to: problem customizing CXXFLAGS in Windows

Why is it that R places CFLAGS after PKG_CFLAGS and not before when compiling a package (e.g. through R CMD build pkg)? This can be problematic if, for instance, you want to use -O3, but -O2 is in R_HOME/etc/Makeconf. If -O2 (in CFLAGS) appears after -O3 (in PKG_CFLAGS), you are left with what you didn't want: -O2. In R-exts, it says that "Flags which are set in file etc/Makeconf

Hi r-devel, a recent install of R-3.4.0 RC (2017-04-13 r72510)? on Linux (Ubuntu 16.04.1 LTS) x86_64-linux-gnu? with?g++ (Ubuntu 5.4.0-6ubuntu1~16.04.4) 5.4.0 20160609 (see?http://bioconductor.org/checkResults/devel/bioc-LATEST/malbec2-NodeInfo.html?for more)? results in CXXFLAGS not containing "-O2" as optimisation flag, there is only " -Wall", while?CFLAGS are happy with

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

Dear all, After reading the manuals (especially R-exts) I haven't found an answer to the following question yet. I was compiling someone else's Fortran routines to make them available with R. Hear, I should not that I don't know anything about Fortran, and I only tried to built a shared library. Linux being my platform of choice when developing for R, I first got everything done

wxRuby 0.6.0 has been released and is now available for download from RubyForge at http://wxruby.rubyforge.org/ This release includes binary builds for Max OS X and MS Windows. Changes in this release include: * Additional widget support in XRC (thanks to Marshall Elfstrand) * Addition of wxScrollbar (thanks to Hans Harmon of Pinnacle Technologies Inc) * Addition of wxGrid event handlers (thanks

Hi, I need to create a Makefile.win for a given package so as to fiddle slightly with the compilation process. My Makefile works fine in Linux but I am having trouble creating Makefile.win for MinGW. I first looked at the commands that Rcmd SHLIB appeared to be running and copied those onto the Makefile. But one step seems to be missing, the creation of the _res.rc file needed by windres

This is fixed in R-rc_2017-04-19_r72555.tar.gz If you are affected by this issue then please test the RC tarball. This is the last chance to detect problems (including those created by the last-minute patch) before the release of R 3.4.0.

In C++ code for use in a R-3.1.0 package, my specific problem is that I would like to use <unordered_map> if it is available, or <tr1/unordered_map> if not, or <map> if all else fails. I (think I) can accomplish this with configure.ac as AC_INIT("DESCRIPTION") CXX=`"${R_HOME}/bin/R" CMD config CXX` CXXFLAGS=`"${R_HOME}/bin/R" CMD config

Hello, In the src folder of my R package I have a.cc b.cc f/g/x.cc my Makevars.in has all: $(SHLIB) upon installing only, a.o and b.o is build and the final dll is comprised of a.o and b.o How can I instruct $(SHLIB) to pick up its source files from all subdirectories (or maybe a subset, though here it will be all) in src ? Much thanks Saptarshi

Hello all - first time poster long time reader, I'm currently working on a package, and was interested to compare performance with and without gcc/g++ -O based optimization. I can turn the -O flags off with a ~.R/Makevars file, but when I do something odd happens. The package installs fine when gcc is fed -O2 or -O3 *install with* R CMD INSTALL --configure-args="CFLAGS=-g CXXFLAGS=-g

Hi Erik, similar to what I did for libsndfile, this is to simplify the handling of adding -D_FORTIFY_SOURCE=2. Regards David

It's both the documented option [1] and it currently differs from CFLAGS in the offending flag: root at 93e09ba5b6fb:/# diff -u <(dpkg-buildflags --get CFLAGS | sed 's/ /\n/g') <(dpkg-buildflags --get

I think this is about the following line in debian/rules: optimflags = `DEB_BUILD_MAINT_OPTIONS=optimize=-lto dpkg-buildflags --get CFLAGS`

Hi, All, I have come across a problem building a DLL from .f90 source (R 2.3.1, Windows XP). When using the R CMD SHLIB procedure, the DLL itself was being built, but its export table was empty. Among the output from R CMD SHLIB the following message appeared: c:\mingw\bin\nm.exe: 'a.out': No such file The reason is the empty list of dependencies in the pattern rule for DLLs

Dear FLAC devs, I would like to get some of our patches merged into master. Most of them deal with adhering to GNU conventions, respectively not overriding flags/variables that are up to the user to set. For instance, honoring $(htmldir) is important, as we have installation paths for the documentation that differ from what is currently coded in the various Makefile.am's. Regards David

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 );
