Hi. In essence, my problem is that I cannot install a package which requires Fortran-77 compilation on my Mac.
More in detail, this is my own package 'mnormt' which exists on CRAN since 2006; it is currently at version 1.5-7. It has been developed in successive versions on a Linux machine, where it compiles with no problems. The macOS and MS-windows versions are created on CRAN, where it passes all pertaining checks. Now, in the new pandemic world, I need create a new version of the package, but working from home, hence using my Mac laptop instead of the Linux desktop as in the past. Unfortunately, compilation or loading does not work. If I run R CMD check mnormt_1.5-7.tar.gz first I get a bunch of warning messages such as Warning: Possible change of value in conversion from REAL(8) to INTEGER(4) .... [-Wconversion] Warning: ‘lxchng’ may be used uninitialized in this function [-Wmaybe-uninitialized] Warning: Label 10 at (1) defined but not used [-Wunused-label] and finally it crashes with Error: package or namespace load failed for ‘mnormt’: .onLoad failed in loadNamespace() for 'mnormt', details: call: dyn.load(file, DLLpath = DLLpath, ...) error: unable to load shared object '/Users/aa/SW-aa/Pkg-mnormt/mnormt.Rcheck/00LOCK-mnormt/00new/mnormt/libs/mnormt.so': dlopen(/Users/aa/SW-aa/Pkg-mnormt/mnormt.Rcheck/00LOCK-mnormt/00new/mnormt/libs/mnormt.so, 6): Symbol not found: ___addtf3 Referenced from: /usr/local/lib/libquadmath.0.dylib Expected in: /usr/local/lib/libgcc_s_x86_64.1.dylib in /usr/local/lib/libquadmath.0.dylib Error: loading failed Needless to say, I have no idea what this "addtf3" is or it should be. There is no such a symbol in the Fortran code. I believe to have installed all ingredients indicated at https://mac.r-project.org/tools/ See the list below with details about my system and other installed tools. Any suggestions for sorting this out?
