Putting everything into one file, surprisingly for me, solved my problem of not being able to nest a sub-state under a super state. Now I need to

Thanks for the recommendation. The problem turned out to be indeed with forward declarations. I wish the compilation errors were somewhat more informative, so that I could find the root cause of the problem easily. -----Original Message----- From: boost-users-bounces@lists.boost.org [mailto:boost-users-bounces@lists.boost.org] On Behalf Of Igor R Sent: donderdag 9 juni 2011 18:33 To: boost-users@lists.boost.org Subject: Re: [Boost-users] [statechart] Is it possible to have nested (sub)states in an asynchronous state machine? figure

out why the previous implementation (i.e., the one distributed over multiple files) does not compile.

I guess you try to use undefined (forward-declared) types in contexts where they cannot be used. _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
