...he symbol in R routines, rather than for other nefarious reasons (?? some fundamental incompatibility with R?) I guess that most of my package users will have an R built without special attention to their lapack library, so will start with something like mtmorgan at gopher4:~> R CMD config LAPACK_LIBS -L/home/mtmorgan/arch/x86_64/R-devel/lib -lRlapack My R is built with --enable-R-shlib, so predictably enough R CMD INSTALL --clean <pkg> is 'successful' (zsysv_ is marked as unresolved in the <pkg>.so, but this doesn't stop compiling and linking). Also predictably enough...

hello, I have a c code which uses clapack. I want to integrate R with this code. It said that I create a R package including my c code. Then build it with putting PKG_LIBS = $(LAPACK_LIBS). I want to know the interface LAPACK_LIBS is Fortran or C? If it is written in Fortran, how can I build them together? If I can build them together, I still use the function in cLapack or the function in LAPACK_LIBS? Could you tell me how I can do in detail? Maggie

..., ptr_ALPHA, X, n, X, n, ptr_BETA, res, q); } In Ubuntu I have no problem in compiling: R CMD SHLIB -llapack myfile.c. However, under Windows the -llapack flag is not recognised and I am able to get the code compiled only if I build an R package with the suitable Makevars file options: PKG_LIBS=$(LAPACK_LIBS) $(FLIBS). Is there a way to get the .dll without resorting to build a package? Thanks in advance, N.

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 It could of cour...

...s a "LTS" = long time support version). apt-get install r-cran-robustbase works fine, but when trying to load the package, there's a DLL - dependency on libRlapack.so which is not fulfilled (and not fulfillable: There's *no* libRlapack.so). For me, $ /usr/bin/R CMD config LAPACK_LIBS -llapack and lapack.so is found inside /usr/lib/R/modules/ and liblapack.so from the 'lapack3' Debian/Ubuntu package is simply in /usr/lib/libpack.so Could it be that this is caused by an Ubuntu / Debian mismatch? Thank you in advance, Martin Maechler, ETH Zurich ------- start o...

...-llapack -lblas By doing this, the procedure does not use subroutines isamax.f, sgefa.f sgesl.f in BLAS, as expected. In fact, there are problems to use these subroutines in BLAS, for some reason.

The Makefile is the following: LIBNAME=car PKG_LIBS = $(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS) OBJS=isamax.o saxpy.o sscal.o foo1.o ... foo20.o -llapack -lblas $(LIBNAME)$(SHLIB_EXT): $(OBJS) $(SHLIB_LD) $(SHLIB_LDFLAGS) -o $@ $(OBJS) $(FLIBS) clean: @rm -f *.o *.$(SHLIB_EXT) realclean: clean Some compiling outputs are the following: g77 -mieee...

...command, R responds that lme4.so was not found. I then uninstalled lme4 and tried again from cran. When the program tried to compile, there was a message that -llapack could not be found, so the package failed to install. If I execute the following: york at sasquatch:~$ /usr/bin/R CMD config LAPACK_LIBS the system responds: -llapack I'm not sure where to go from here. Is -llapack installed but R can't find it, eg, is there a faulty link somewhere? Has anyone else had this problem and solved it? Anne

...wcastle.edu.au/ and finally found that email address where I can maybe find some help. Well my main goal is to get to use the lapack library within my R package (which can be done using calls from C). But in order to do this I have to create a file src/Makevars with the following line : PKG_LIBS=$(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS) However when I create this file, my package won't build anymore. Actually the checking results in the following : mingw32\bin\ld.exe: cannot find -lg2c collect2: ld returned 1 exit status make[3]: *** [PACKAGE.dll] Error 1 make[2]: *** [srcDynlib] Error 2 make[1]: *** [...

...k.h: No such file or directory Can someone explain to me how I should include the headers to this AWESOME wrapper code to the LAPACK libraries?

I initially posted this question on the general list, but I didn't get any responses.
