Ich arbeite derzeit an einer C++ IMAP-Bibliothek, so dass ich einige zugegeben rostige C++ - Fähigkeiten verbessern kann. Ich möchte die Bibliothek so portabel wie möglich machen, damit ich sie über das gesamte Betriebssystem nutzen kann, und wenn ich mich verrückt fühle, vielleicht sogar auf einem mobilen Gerät. Zu diesem Zweck habe ich einige Nachforschungen angestellt und beschlossen, Boosts Asio-Bibliothek zu verwenden.Boost Asio und OpenSSL 1.1.0
Ich konnte Boost in meinem Projekt selbst bauen und ausführen. I Ereignis machte einen einfachen HTTP GET zu google.com. Leider muss ich in der Lage sein, mit TLS zu kommunizieren, und ich bin auf Probleme gestoßen, die Asios SSL-Funktionalität zu verwenden versuchen.
Ich habe sowohl Boost als auch OpenSSL aus der Quelle erstellt, mit Standardeinstellungen (alles ist in/usr/local). Ich benutze auch CMAKE um mein Projekt zu erstellen. Unten ist meine CMAKE Datei:
cmake_minimum_required(VERSION 3.2)
project(IMAP)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
message(WARNING "Starting CMAKE...")
set(SOURCE_FILES main.cpp)
add_executable(IMAP ${SOURCE_FILES})
find_package(Boost COMPONENTS system thread regex REQUIRED)
message(WARNING "Boost_INCLUDE_DIR: ${Boost_INCLUDE_DIR}")
message(WARNING "Boost_LIBRARIES: ${Boost_LIBRARIES}")
message(WARNING "Boost_VERSION: ${Boost_VERSION}")
include_directories(${Boost_INCLUDE_DIR})
target_link_libraries(IMAP ${Boost_LIBRARIES})
find_package(OpenSSL REQUIRED)
message(WARNING "OpenSSL_VERSION: ${OPENSSL_VERSION}")
message(WARNING "OpenSSL_INCLUDE_DIR: ${OPENSSL_INCLUDE_DIR}")
message(WARNING "OpenSSL_LIBRARIES: ${OPENSSL_LIBRARIES}")
include_directories(${OPENSSL_INCLUDE_DIR})
target_link_libraries(IMAP ${OPENSSL_LIBRARIES})
Und dies ist die Ausgabe meiner CMAKE Nachrichten:
Warning:Starting CMAKE...

Wenn ich versuche, das Projekt, das ich die folgenden Haufen von Fehlern erhalten zu bauen:

Es sieht für mich so aus, als käme es nicht einmal in die Verknüpfungsstufe der Kompilierung, es versucht nur, die .o-Datei für meine main.cpp zu erstellen. Wenn ich eine der Dateien öffne, über die sie sich in meiner IDE beschwert, gibt mir die IDE eine Syntaxfehler-Hervorhebung, aber ich bin ratlos, warum.
Habe ich die Includes in die falsche Reihenfolge gebracht? Gibt es ein Problem mit meiner CMAKE-Datei? Habe ich OpenSSL oder Boost falsch erstellt?
Jede Hilfe wäre willkommen. Ich arbeite seit ein paar Wochen daran und habe die meiste Zeit damit verbracht es zu bauen (C++ Lektion 1, denke ich :)).
Jetzt auf OpenSSL RT geöffnet ... [Problem 4547: Ändern der Funktion CRYPTO_num_locks() zu "# define CRYPTO_num_locks() (0)" bricht kompiliert] (https://rt.openssl.org/Ticket/Display.html ? id = 4547 & user = guest & pass = Gast). Das Projekt könnte die Schmerzen lindern; oder sie schlagen Schutz basierend auf Versionsverwaltung und alternativen Codepfaden vor. Wenn OpenSSL letzteres vorschlägt, müssen Sie einen Fehlerbericht mit Boost öffnen. Es ist nicht ungewöhnlich, dass OpenSSL Programme aufgrund von Symboländerungen auf Minor-Version-Bumps (d. H. 1.0.2 bis 1.1.0) unterbricht. Ihre Führung mag es erlauben, aber ich habe nicht nach den Richtlinien gesucht. – jww
Ich landete wieder auf 1.0.2 und alles hat funktioniert. Vielen Dank! –
