The binaries (sage-7.4-Ubuntu_16.04-x86_64.tar.bz2) seemed to unpack ok (on Ubuntu 16.04), but the command "sage", crashes.
The crash report has right at the end of the report, "ImportError: libgfortran.so.3: cannot open shared object file: No such file or directory ". (Presumably the previous stuff is pointing out the various commands or calls ending up at this point?) Any ideas please on how to get it working? Do I need a Fortran library? Why? Why assume I have it? (There's no mention of possible dependencies like this on the Ubtuntu or Sagemath install help pages.) Other possibly useful info: - the command did a lot of patching first time - I'm pretty new to linux -- You received this message because you are subscribed to the Google Groups "sage-support" group.
