我如何正確重寫下一個源代碼?它是GLib驅動的IRC-bot的一部分。編譯器崩潰,並顯示下一個錯誤:爲什麼下一個代碼不能編譯?
src/irc.cpp:20:9: error: cannot call member function ‘Glib::ListHandle<Glib::RefPtr<Gio::InetAddress> > Gio::Resolver::lookup_by_name(const Glib::ustring&, const Glib::RefPtr<Gio::Cancellable>&)’ without object
),
來源:
#include "includes.hpp" // Just including all the files
Glib::RefPtr<Gio::Socket> ircSock; // Our socket
void ircInit() { // Init-function
try {
ircSock = Gio::Socket::create(// Creating socket
Gio::SocketFamily::SOCKET_FAMILY_IPV4,
Gio::SocketType::SOCKET_TYPE_STREAM,
Gio::SocketProtocol::SOCKET_PROTOCOL_TCP
);
ircSock->connect(// Problematic code
Gio::InetSocketAddress::create(
Gio::Resolver::lookup_by_name(
"irc.freenode.net", // For-example
Gio::Cancellable::create()
),
6667
),
Gio::Cancellable::create()
);
} catch(const Glib::Error& e) {
std::cerr << "IRC: Error: " << e.what() << std::endl; // Error-reporting
}
}
因爲它是一個成員函數。你不能把它稱爲靜態函數。 –
