Hi Andreas,
Many thanks for your help first of all!
Upon your request, I wrote a small but complete program that demonstrates
the issue. This program consists of 5 source code files:
1) main.cpp
2) StateMachine.hpp
3) StateMachine.cpp
4) SuperState.hpp
5) SubState.hpp
The contents of these files are listed at the end of this e-mail. You should
be able to compile these listings and then run the executable successfully.
Depending on your compiler flags, you may receive one warning that says "/*
within comment". This is intentional, so please ignore the warning.
To reproduce my problem regarding the nesting of states, please modify the
listings in three locations, as explained in the comments in SuperState.hpp
and SubState.hpp, and then re-compile. You should receive multiple errors
pointing to the Boost Statechart library.
Looking forward to your feedback.
Thanks & Regards,
Gurcan
