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 comp...

Hello! I might have found a bug in the way that R handles Makevars file when building a package. Value of variable CXX_STD is ignored - i.e. R does not use the correct compiler/flags - if there are no *.cpp files directly in the src/ directory (e.g. all *.cpp are in subdirectories, and OBJECTS variable is set accordingly). Adding a bogus *.cpp file fixes this issue. However, this is not very obvious (I would dare sayin...

...XXFLAGS` AC_CONFIG_HEADERS([src/config.h]) AC_LANG(C++) AC_CHECK_HEADERS([unordered_map tr1/unordered_map]) AC_OUTPUT Use of configure.ac does not seem to be entirely consistent with section 1.2.4 of Writing R Extensions, where one is advised that to use C++(11? see below) code one should CXX_STD = CXX11 in Makevars(.win). 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...

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....

...of the src/Makeconf file of my package (it is fairly standard I believe for a package using RcppEigen): PKG_CXXFLAGS = -I../inst/include -DEIGEN_DONT_PARALLELIZE $(SHLIB_OPENMP_CXXFLAGS) PKG_LIBS = `$(R_HOME)/bin/Rscript -e "Rcpp:::LdFlags()"` $(SHLIB_OPENMP_CXXFLAGS) CXX_STD = CXX11 and that of rrcov (which I m using for illustration's sake): PKG_LIBS=$(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS)

Hi, I can not install packages from source which links to RcppArmadillo on Ubuntu 20.04 (after upgrading from 18.04). The following problem occurs: ** testing if installed package can be loaded from temporary location Error: package or namespace load failed for 'myPackage' in dyn.load(file, DLLpath = DLLpath, ...): unable to load shared object

Dear list, During the last two months, I spent a lot of time trying to remove the following warnings of my package randtoolbox: congruRand.c:180:3: warning: ISO C does not support the 'I64' ms_scanf length modifier [-Wformat=] sscanf(params[0], "%" PRIu64 "\n", &inp_mod); Please see

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
