Kompilieren Sie Fehler bei der Einbeziehung von Boost 1.79.0 Bimap mit Unreal 5 ⇐ C++

[Anonymous]

Über ein Jahr lang habe ich Boosts Bimap für die Grundlage eines Bestandssystems verwendet. < /p>
typedef boost::bimap InventoryBimap;
< /code>
Nach der Aktualisierung von Unreal 4 zu Unreal 5 habe ich jedoch einige andere Änderungen vorgenommen. Ich bin von Boost 1.68.0 auf 1.79,0 bewegt. Ich bin von C ++ 17 nach C ++ 20 umgezogen. > Es gibt zwei Quellen für eine Reihe von Kompilierungsfehlern, die verhindern, dass mein Spiel zusammengestellt wird: < /p>

Der zweite Fehler wiederholt sich für jede einzelne Vorlage innerhalb von allocator_access.hpp. Kommentieren Sie das gesamte Bimap in meinem Projekt.>
