[Rd] R 3.4 has broken C++11 support

Hi!

Well, my linux distribution has very recent versions
of everything, so a working C++11 compiler exists:

$ gcc --version | head -n1
gcc (GCC) 6.3.1 20170306

Could wrong ./configure options be at fault here? See:

https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=r-devel#n40

My sessionInfo():

$ R-devel --slave -e 'sessionInfo()' | head -n3
R Under development (unstable) (2017-04-18 r72542)
Platform: x86_64-pc-linux-gnu (64-bit)
Running under: Arch Linux

Thanks, Philipp

I am on Fedora 25 which also uses gcc 6.3.1. The default standard for
6.3.1 is C++14. The output from configure should contain these lines:

? Default C++ compiler:??????g++???
? C++98 compiler:????????????g++ -std=gnu++98?
? C++11 compiler:????????????g++ -std=gnu++11?
? C++14 compiler:????????????g++??
? C++17 compiler:??????????????

Please check.

Maybe you can share with us how you configure the build of R-devel?  I tend
to locally build every week or so and I have the following on Ubuntu 16.10:

  CXX = ccache g++ 
  CXXCPP = $(CXX) -E
  CXXFLAGS = -ggdb -pipe -Wall -pedantic $(LTO)
  CXXPICFLAGS = -fpic
  CXX98 = ccache g++
  CXX98FLAGS = -ggdb -pipe -Wall -pedantic
  CXX98PICFLAGS = -fpic
  CXX98STD = -std=gnu++98
  CXX11 = ccache g++
  CXX11FLAGS = -ggdb -pipe -Wall -pedantic
  CXX11PICFLAGS = -fpic
  CXX11STD = -std=gnu++11
  CXX14 = ccache g++
  CXX14FLAGS = -ggdb -pipe -Wall -pedantic
  CXX14PICFLAGS = -fpic
  CXX14STD = 
  CXX17 = 
  CXX17FLAGS = 
  CXX17PICFLAGS = 
  CXX17STD = 

I call configure in build shell script (which has not changed in years) with 

  R_PAPERSIZE=letter				\
  R_BATCHSAVE="--no-save --no-restore" 		\
  R_BROWSER=xdg-open				\
  PAGER=/usr/bin/pager				\
  PERL=/usr/bin/perl				\
  R_UNZIPCMD=/usr/bin/unzip			\
  R_ZIPCMD=/usr/bin/zip				\
  R_PRINTCMD=/usr/bin/lpr			\
  LIBnn=lib					\
  AWK=/usr/bin/awk                              \
  CC="ccache gcc"				\
  CFLAGS="-ggdb -pipe -std=gnu99 -Wall -pedantic" \
  CXX="ccache g++"				\
  CXXFLAGS="-ggdb -pipe -Wall -pedantic" 	\
  FC="ccache gfortran"	 	  		\
  F77="ccache gfortran"				\
  MAKE="make -j4"				\
  ./configure 					\
      --prefix=/usr/local/lib/R-devel 		\
      --enable-R-shlib 				\
      --without-blas 				\
      --without-lapack 				\
      --without-recommended-packages

Works here ...

here you go, it?s pretty much the simplest package possible that needs C++11:

https://github.com/flying-sheep/cxx11test
> Maybe you can share with us how you configure the build of R-devel?
Sure, in the mail you quoted, I already linked exactly that:

https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=r-devel#n40
> ./configure --prefix=/opt/r-devel \
>	--libdir=/opt/r-devel/lib \
>	--sysconfdir=/etc/R-devel \
>	--datarootdir=/opt/r-devel/share \
>	  rsharedir=/opt/r-devel/share/R/ \
>	  rincludedir=/opt/r-devel/include/R/ \
>	  rdocdir=/opt/r-devel/share/doc/R/ \
>	--with-x \
>	--enable-R-shlib \
>	--with-lapack \
>	--with-blas \
>	F77=gfortran \

Thanks and cheers,
Philipp
