Компоновщик не может найти библиотеку, хотя библиотека находится в пути поиска ⇐ C++

[Anonymous]

Я использую команду ниже для кросс-компиляции aarch64 на платформе linux-x86_64, но компоновщик не может найти libstdc++, хотя /usr/aarch64-linux-gnu/lib/libstdc++.so.6 действительно существует, может кто-нибудь знает, почему ? большое спасибо
