Hi All, Sorry for my previous email: there was some issue with my email system. Hope you don't have any problems with reading my message now. Aaron, Not long ago I met a problem related to clang attributes implementation. I tried to add a new CXX11 attribute with separated namespace like here: def FooAligned : InheritableAttr { let Spellings = [CXX11<"_Foo_attrs", "aligned">]; …. But I was not able to do it because name “aligned” was used in another well-known attribute. After some research I found that t...

...t (I?m using the mirror to have a working link) broke C++11 compilation. Before (and still now, according to the comments in the configure script), it?s sufficient to just have ?SystemRequirements: C++11? in the DESCRIPTION file. But now ?R CMD install? fails with ?C++11 standard requested but CXX11 is not defined?, which is, according to the documentation , a lie. I can?t even circumvent this, as setting ?CXX11=$(CXX)? in the src/Makevars file fails with ?CXX definition recursive?, and hardcoding ?CXX11=g++? is a bad idea. Did I do sth. wrong or is the C++11 support in R just broken atm.?...

R 3.4 has 'experimental' support for setting CXX_STD to CXX98 / CXX11 / CXX14 / CXX17. However on most platforms, the R configuration seems to leave the CXX1Y and CXX1Z fields blank in "${R_HOME}/etc/Makeconf" (rather than falling back on default CXX). Therefore specifying e.g CXX_STD= CXX14 will fail build with cryptic errors (due to compiling with CXX=&q...

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()") PKG_CXXFLAGS = $(SHLIB_OPENMP_CXXFLAGS) -I../inst/include Best, Sam On Thu, Oct 8, 2020 at 3:39 PM Dirk Eddelbuettel <edd at debian.org>...

A user with the email address flying-sheep at web.de has submitted a bug report on this topic.? https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17260 Assuming that you are the same person, I will address the issue here first. If you get the message ?C++11 standard requested but CXX11 is not defined? then this means that there is no available C++11 compiler on your computer. The presence or absence of a working C++11 compiler is determined at configure time when R is built. The tests used by R's configure script to determine C++11 support are more stringent in R 3.4.0 than...

...rsion). The clang++ runs as expected when I compile a hello program with c++11 enabled. I created a project (copied from sample/) where there are some C++ source files with c++11 features. I configured my project using the following command: $ CXXFLAGS="-std=c++11" ../configure --enable-cxx11 However, I found that the clang++ did not build my project with the " -std=c++" option[1]. Could anyone kindly show me how to enable C++11 in a LLVM project, please? Thank you. Miangliang. [1] I get the detailed options building my project using 'make VERBOSE=1' -- Mingliang L...

Hi, I use the following line to configure, which can enable the c++11 in the project building. However, I don't think it's an elegant way to do the trick. $ CXX="clang++ -std=c++11" ../configure I don't know why "-enable-cxx11" doesn't work as expected when I configure the project. Regards.

My code does not require a compiler that supports the full C++11 feature set. In addition, I do not understand the logic of setting a variable that influences compiler flags in Makevars -- configure.ac will see a compiler with inaccurate flags. Is use of configure.ac orthogo...
