Hi, Two months ago I released a package I developed in Debian 9 GCC ( https://CRAN.R-project.org/package=uFTIR). The package was accepted on CRAN, and it can be installed on Windows and Linux machines. However, it is not working on MacOS. I don't know why. The problem starts after the installation, as the OS cannot load the compiled code. Cutting the long paths of CRAN, the problem looks like (for r-oldrel-osx-x86_64):
... ** testing if installed package can be loaded from temporary location Error: package or namespace load failed for ‘uFTIR’ in dyn.load(file, DLLpath = DLLpath, ...): unable to load shared object '.../libs/uFTIR.so': dlopen(.../libs/uFTIR.so, 6): Symbol not found: _H5P_CLS_DATASET_CREATE_ID_g Referenced from: .../libs/uFTIR.so Expected in: flat namespace in .../libs/uFTIR.so Error: loading failed ... (The missing symbol for r-release-osx-x86_64 is a different one: _jpeg_resync_to_restart) I saw this thread (https://github.com/RcppCore/RcppArmadillo/issues/224) about Rcpp, but CRAN is not using gcc, but clang, so it is not really the same... although I was lost when they discussed about libc++ and libstdc++. I also saw this thread from stackoverflow ( https://stackoverflow.com/questions/40922814/error-in-dyn-loaddllfile-unable-to-load-shared-object-expected-in-flat-na) but I don't have a mix between cpp and plain c. I think that probably has to do with my Makevars file ( https://community.rstudio.com/t/error-during-the-installation-of-utf8-package/4005/2)... maybe I shouldn't use PKG_LIBS and LDLIBS instead? But if I change it, how will it affect the -already successful- installations on windows and linux? The Makevars for Mac and Linux is: CXX_STD = CXX11 PKG_CXXFLAGS = $(SHLIB_OPENMP_CXXFLAGS) `pkg-config --cflags gdal` PKG_LIBS = $(SHLIB_OPENMP_CXXFLAGS) $(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS) `pkg-config --libs gdal` I will appreciate a hint, Fabio. -- [[alternative HTML version deleted]] ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
