So does VS2008. Frankly, I'm not sure whether GCC is too lazy or VS too eager. But it shouldn't matter, if the whole machine is in one TU, you should be able to fix this by shuffling around includes (unless I'm missing something).
Ok. By TU I take that to be one cpp file with its includes. For maintenance reasons it appears the model was broken up into multiple cpp files.
Ok, please disregard my previous post then.
It seems the model was structured under gcc that every inner level is a new header that just includes its parent, but not any children (inners).
Ok, just so that I understand the organization of the GCC source correctly: What does the cpp that contains the call to state_machine<>.initiate() include *directly* and *indirectly*? From your description, it only includes some of the headers defining the states, correct? -- Andreas Huber When replying by private email, please remove the words spam and trap from the address shown in the header.
