I’m trying to use boost::signal to implement a callback mechanism, and I’m getting a memory access assert in the boost::signal code on even the most trivial usage of the library. I have simplified it down to this code:

#include <boost/signal.hpp>  typedef boost::signal<void (void)> Event;  int main(int argc, char* argv[]) {      Event e;      return 0; }

Thanks!

Edit: This was Boost 1.36.0 compiled with Visual Studio 2008 w/ SP1. Boost::filesystem, like boost::signal also has a library that must be linked in, and it seems to work fine. All the other boost libraries I use are headers-only, I believe.

  1. I’ve tested your code on my system, and it works fine. I think that there’s a mismatch between your compiler, and the compiler that your Boost.Signals library is built on. Try to download the Boost source, and compile Boost.Signals using the same compiler as you use for building your code.

    Just for my info, what compiler (and version) are you using?
