链接libopencv_java3.so时符号表报错问题

前言

本文为记载常见过错文章，并非技术共享文。

问题如下:

CmakeList中链接libopencv.so。编译时报错。

详细报错代码：

解决办法

网上看到了很多解决办法，都来源于这篇文章：local symbol ‘__bss_start’ in global part of symbol table” only in Android NDK aarch64 build]

最后文章中有人提到了，更换ndk版别。经测试，更换NDK到21.4.xxx版别及以下都可以编译。如下图：

注意事项

该问题仅存在于arm64-v8a中，armeabi-v7a中并无问题。
