syntax error : identifier 'heap_memory

This error occurs in BaseManager.cpp, I have no idea why, but it's related to Boost.

Any help ?

Er, we don't use boost in MyGUI.
Ogre use it if you enabled it. Check your Ogre builds.

Well then that's the problem, MyGUI seems to be conflicting with something Boost defines.

I'll look into it.

---- Done ----

Adding BOOST_NO_RVALUE_REFERENCES to the Preprocessor definitions did it.

(Note: You need to add that to every project that causes the error.)
