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> wrote: > > Sam, > > PS I...

...ewbie with writing C++ extensions and have not much understanding of the Makevars file, I am unsure what to write into it. Currently I have: ## Use the R_HOME indirection to support installations of multiple R version PKG_LIBS = `$(R_HOME)/bin/Rscript -e "Rcpp:::LdFlags()"` KG_CFLAGS = $(SHLIB_OPENMP_CXXFLAGS) PKG_LIBS = $(SHLIB_OPENMP_CXXFLAGS) ## -- compiling for OpenMP PKG_CXXFLAGS=-fopenmp ## ## -- linking for OpenMP PKG_LIBS= -fopenmp -lgomp Obviously compilation fails with error: R CMD INSTALL OpenMPTest Symbol not found: __ZTIN4Rcpp19index_out_of_boundsE With standard setup of the above Makeva...

.... My questions are what is causing my package's cpp code to be compiled in -o2 and how to fix this? Here is the content 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

...onfig not found, is GSL installed?]) fi # Now substitute these variables in src/Makevars.in to create src/Makevars AC_SUBST(GSL_CFLAGS) AC_SUBST(GSL_LIBS) AC_OUTPUT(src/Makevars) And here is Makevars.in: GSL_CFLAGS = @GSL_CFLAGS@ GSL_LIBS = @GSL_LIBS@ PKG_LIBS=$(GSL_LIBS) $(SHLIB_OPENMP_CFLAGS) $(SHLIB_OPENMP_CXXFLAGS) PKG_CFLAGS=$(GSL_CFLAGS) $(SHLIB_OPENMP_CFLAGS) PKG_CXXFLAGS=$(SHLIB_OPENMP_CXXFLAGS) Any help would be greatly appreciated. I don't have access to Solaris which makes the debugging rather hard. Best regards, Jouni Helske [[alternative HTML version deleted]]
