As far as I remember MSM uses fusion under the hood for states, so FUSION_MAX_VECTOR_SIZE would have to be set as well. Kris On Mon, Sep 22, 2014 at 5:25 PM, Hickman, Steve (AdvTech) < Steve.Hickman@honeywell.com> wrote:

I’ve been able to successfully create larger MSM state machines. Are you **absolutely** sure that the defines are before **any** inclusion of Boost? I use Visual Studio. For me, this meant I had to include these defines at the top of my precompiled header include file.

Hi,

I tried defining:

#define BOOST_MPL_CFG_NO_PREPROCESSED_HEADERS

#define BOOST_MPL_LIMIT_VECTOR_SIZE 30 // or whatever you need

#define BOOST_MPL_LIMIT_MAP_SIZE 30 // or whatever you need

/// Boost-MSM Includes

// back-end

#include "boost/mpl/vector/vector30.hpp"

#include <boost/msm/back/state_machine.hpp>

//front-end

#include <boost/msm/front/state_machine_def.hpp>

#include <boost/msm/front/functor_row.hpp>

#include <boost/any.hpp>

// for And_ operator

#include <boost/msm/front/euml/operator.hpp>

And i still get the following errors:

You think the problem is with states? But before I defined the mpl no preprocessed header macro all compiles well except that I have 21 states which is beyond the limit When I define the no preprocessed header macro I get this weird warnings. Do I need to define those macros in my dependencies project as well? Since they use some boost.. On Sep 22, 2014 9:53 PM, "Christophe Henry" < christophe.j.henry@googlemail.com> wrote:

It’s hard to help without code but you might need to increase fusion too if you happen to have more than 10 states, as written by Krzysztof: #define FUSION_MAX_VECTOR_SIZE 20

Can you provide a minimal code reproducing the problem? It is of course possible to have more than 20 transitions so you either have more than 10 states or your limit macro has been defined somewhere else.

Then it’s definitely wrong. Frankly, don’t rely too much on the compiler to not compile if you exceed the limit. I once saw a fsm with 40 transitions and 30 states and gcc never complained, never understood why.

You need to define it in the TU including the msm headers. If you include msm from a header (which you should avoid) you might get a conflict so you’d have to define it for all, which would everywhere increase compile-times so don’t do it.
