c++ – error when using webrtc lib into my QT project
i got a webrtc lib that have been compiled and could be use directly,My pure C++ project could use it, and i got many errors when using webrtc lib into my QT project,it compile error at the sigslot.h,how to solve it?
the error is at the WebRTC\include\rtc_base\third_party\sigslot.h file
// time.
template <typename... Args>
void emit(Args... args) const {
typedef void (*em_t)(const _opaque_connection*, Args...);
union_caster<emit_t, em_t> caster;
caster.from = pemit;
(caster.to)(this, args...);
}
