In my project (using asio) I have something like this:
void Foo::myCallback(const boost::system::error_code &e) { if(e == boost::asio::error::operation_aborted) { // bla bla... } }
This call is made across a shared dll and I notice that for a "strange" reason e == boost::asio::error::operation_aborted was always false.
I discover that when the temporary object boost::system::error_code is constructed from the constants boost::asio::error::operation_aborted the error_code's costructor take a pointer to a "error_category" and the comparison operator is (m_cat is an error_category pointer):
inline friend bool operator==( const error_code & lhs, const error_code & rhs ) { return lhs.m_cat == rhs.m_cat && lhs.m_val == rhs.m_val; }
In my situation (using shared modules) lhs.m_cat == rhs.m_cat points to differents memory regions (even if are of the same type "system_category") because of the static initialization in the function "get_system_category".
Are you using the dll version of boost_system? You need to so that there will only be one copy of the get_system_category function. Cheers, Chris P.S. please don't mail to both lists separately -- it made your emails get flagged as spam for me.
