Unable to determine OS

When I go on terminal (i installed smlnj) and i type sml it gives me the error sml: unable to determine architecture/operating system. What does this mean??? I installed sml like this at this website, but I'm not sure -- are the instructions wrong?

Solution

  • If you're using OSX 10.8 or later (uname -r gives you something starting with 12 or higher), SML/NJ pre 110.75 doesn't work too well without some extra tweaking. It's a known issue that can be fixed by adding the 10.8 choice (see the 12 line below) to the OS detection code in .arch-n-opsys:

        :
    10*) OPSYS=darwin; HEAP_OPSYS=darwin ;; # MacOS X 10.6
    11*) OPSYS=darwin; HEAP_OPSYS=darwin ;; # MacOS X 10.7
    12*) OPSYS=darwin; HEAP_OPSYS=darwin ;; # MacOS X 10.8
    13*) OPSYS=darwin; HEAP_OPSYS=darwin ;; # MacOS X 10.9 Mavericks
    14*) OPSYS=darwin; HEAP_OPSYS=darwin ;; # MacOS X 10.10 Yosemite
    15*) OPSYS=darwin; HEAP_OPSYS=darwin ;; # MacOS X 10.11 El Capitan
    16*) OPSYS=darwin; HEAP_OPSYS=darwin ;; # MacOS X 10.12 Sierra
    17*) OPSYS=darwin; HEAP_OPSYS=darwin ;; # MacOS X 10.13 High Sierra
