Hi,
I am installing the latest HOL 4 in ubuntu 16.04. I have followed the steps
given in the tutorial to complete the installation. When I input bin/hol for
entering the HOL system, I failed, and the system prompted:
Error trying to use the file:'/home/liu/hol/bin/hol.ML'
if I input:/home/liu/hol/bin/hol.ML, the system prompted no such file or dir.
However, I have this file and dir.
I have installed poly/ml-5.6 successfully, I can enter it. Now I don't know how
to enter HOL. Could you help me?
In addition, After the step of bin/build, the system prompted:
Writing HOLPage
*** Can't see dot executable at /usr/bin/dot; not generating theory-graph
*** You can try reconfiguring and providing an explicit path
*** (val DOT_PATH = "....") in
*** tools-poly/poly-includes.ML (Poly/ML)
*** or
*** config-override (Moscow ML)
***
*** (Under Poly/ML you will have to delete bin/hol.state0 as well)
***
*** (Or: build with -nograph to stop this message from appearing again)
I do not know whether this is the reason for.
Thanks,
Liu
