Я попытался запустить Valgrind MemCheck в Android Orea 8.1 с помощью оболочки adb.Но изначально это дало много ошибок, я взломал его до этого момента.Теперь я получаю эту ошибку.
Valgrind устарел из AOSP.Но мне нужно было использовать memcheck в моих службах Android и некоторых нативных службах.
Взлом, который я сделал, чтобы заставить его работать до сих пор, выглядит следующим образом: 1. Изменил расположение библиотеки из / system / lib64 / valgrind в /system / lib64 в файле Android.mk.2. Изменено разрешение memcheck-arm64-linux до 777.
Теперь у меня есть это предупреждение и некоторые ошибки в linker64.
