Hello,
It seems that Accumulators and Signals2 have problems to coexist. For instance, look at the following simple C++ program:
--- [c++] --- #include <boost/accumulators/accumulators.hpp> #include <boost/accumulators/statistics/stats.hpp> #include <boost/accumulators/statistics/mean.hpp> #include <boost/signals2.hpp>
int main() { } In file included from ./boost-trunk/boost/signals2.hpp:20:0, from boost_signals2_accumulators.cpp:4: ./boost-trunk/boost/signals2/signal_type.hpp:29:2: error: #error This header requires BOOST_PARAMETER_MAX_ARITY to be defined as 7 or greater prior to including Boost.Parameter headers
The error is pretty clear and #define BOOST_PARAMETER_MAX_ARITY 7 at the top of your program fixes it. Cheers, Gordon
