Hi Liu,
So far as I understand, you are able to install the polyml-5.6 and also
build the HOL4 using bin/build command. The next step is to run the HOL by
typing bin/hol command at the HOL directory. For instance,
~/Downloads/HOL-kananaskis-10$ bin/hol
---------------------------------------------------------------------
HOL-4 [Kananaskis 10 (stdknl, built Sun Jan 22 07:15:20 2017)]
For introductory HOL help, type: help "hol";
To exit type <Control>-D
---------------------------------------------------------------------
I hope it helps...:)
