Both Professor Doug Bates and I have been overloaded, and so this has slipped. On my system (NixOS Linux distribution, http://nixos.org) I can't compile package Matrix unless this file is deleted. Most likely you have not installed the C++ compiler (which is usually g++ on Linux) -- but you shouldn't need to in order to install R. Indeed, currently a C++ compiler for compiling/linking the R sources should not be needed just because of dummy.cpp in Matrix; and hence I've removed it for the next version of Matrix. However, as said above, I strongly believe your OS / R setup should be amended in such a way that you can also easily install packages with C++ code.

My g++ compiler can't handle the -lgfortran switch, while gcc can. I think it is the fault of my Linux distribution (http://nixos.org), but it was an easier solution to use gcc instead of g++ than fixing g++. This probably means that I can't compile any R packages using C++ and fortran at the same time. I will investigate further in this error. Yes, there is no guarantee that you can mix any two languages except C and Fortran. But this is not the way a Linux system is usually set up, and you may be able to resolve it by including the path to libgfortran in LD_LIBRARY_PATH, or editing FLIBS in R_HOME/etc/Makeconf to be something like -L /path/to/gfortran -rpath=/path/to/gfortran -lgfortran This was the error: g++ -shared -L/usr/local/lib -o Matrix.so CHMfactor.o Csparse.o TMatrix_as.o Tsparse.o init.o Mutils.o chm_common.o cs.o cs_utils.o dense.o dgCMa trix.o dgTMatrix.o dgeMatrix.o dpoMatrix.o dppMatrix.o dsCMatrix.o dsyMatrix.o dspMatrix.o dtCMatrix.o dtTMatrix.o dtrMatrix.o dtpMatrix.o factor izations.o ldense.o lgCMatrix.o sparseQR.o abIndex.o CHOLMOD.a COLAMD.a AMD.a -L/tmp/nix-build-l8rd1zk5f2fslzm7w1zygwz376br9nlw-r-lang.drv-0/R-2. 12.0/lib -lRlapack -L/tmp/nix-build-l8rd1zk5f2fslzm7w1zygwz376br9nlw-r-lang.drv-0/R-2.12.0/lib -lRblas -lgfortran -lm /nix/store/bwwd0qz5ar7afhxdb26bjglql86hcw6b-binutils-2.20/bin/ld: cannot find -lgfortran collect2: ld returned 1 exit status Best regards, Ambrus Kaposi -- Brian D.

[Rd] package matrix dummy.cpp
Hi, The recommended package matrix contains an empty file src/dummy.cpp which results in using g++ instead of gcc to link Matrix.so. What is the reason for that? Is there any difference between using g++ or gcc? (There are no other cpp files in the source) I asked the maintainers of the package (matrix-auth...@r-project.org) 3 weeks ago but haven't received any answer. On my system (NixOS Linux distribution, http://nixos.org) I can't compile package Matrix unless this file is deleted.
