Question

我正在学习如何使用OpenCV编写C ++代码，我想在Android中运行它。我使用Android Studio。

我创建了一个支持C ++的新简单项目，然后我将测试代码添加到C ++文件中。看来，我自己的文件编译和链接。

现在，我认为与我的项目无关的其他因素导致许多错误。它似乎是NDK内部的东西。它可能是最新版本中的错误，如果是这样，我该怎么办呢？

Answer 1

您可以通过在CMakeLists.txt之前向add_library()添加以下内容，而不是从NDK16降级到NDK14，您仍然可以使用NDK16：

set(CMAKE_SHARED_LINKER_FLAGS "${CMAKE_SHARED_LINKER_FLAGS} -Wl,--exclude-libs,libippicv.a -Wl,--exclude-libs,libippiw.a")

Answer 2

我恢复到NDK 14.1.3816874而不是使用当前最新的NDK 16.1.4479499，错误消失了。

您可以在此处找到较旧的NDK：https://developer.android.com/ndk/downloads/older_releases.html

我希望这有帮助！
