Hitting the CAPACITY roof

[DonMathi]

Hi Andrew

Next quest for you. My state machine has become so large that it complains about (line 1013)
static_assert(UNIT+(WIDTH+7)/(sizeof(Unit)*8)<=CAPACITY,"");

How do I change the CAPACITY limit?

[DonMathi]

I have somthing like this: M=Machine, H=Head, S=State, O=Orthogonal, C=Composite

M(H,
S,
O[H,
    C{H,
        S,
        S,
        O[H,
            C{H,S,S},
            C{H,S,S,S}
        ]
    },
    C{H,
        S,
        C{H,S,S},
        C{H,S,S},
        C{H,S,S},
        S
    }
],
S
)

Hi Kjeld,
Looks like a bug, looking into that.

[andrew-gresyk]

Fixed in Beta 7.3

[DonMathi]

Great, thank you

[DonMathi]

I still had some issues, but now I also #include <memory>, this helps.
Do you require some extra libs, that are not included in your machine.hpp file?

[andrew-gresyk]

Nope, HFSM doesn't have any other dependencies.
Are you saying you needed to #include <memory> to fix an HFSM2 build issue?

[DonMathi]

Yes. Without it complains about new for many different things inside hfsm2.
Maybe #include <memory> is not the direct needed dependency, but it solves the problem

[andrew-gresyk]

Do you have an example I can look at?
Also, which compiler are you on?

[DonMathi]

MinGW64 version 8.1.0
Issue at line 577 in your machine.hpp

error: no matching function for call to 'operator new(sizetype, hfsm2::detail::Array<hfsm2::detail::RequestT<hfsm2::EmptyPayload>, 8>::Item*)'

  new (&_items[_count]) Item{std::move(value)};
  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[andrew-gresyk]

Interesting.
Do any of the bundled examples compile on your platform?

[andrew-gresyk]

Added #include <new> for all platforms.
Let me know if this fixes the issue.

[DonMathi]

Yes, that solves the issue
