Android 对大量caffe2库的未定义引用

我遇到的错误与此处描述的相同：

但是，在使用解决方案后，我们会得到另一种类型的错误：

似乎导入的

caffe2

目标缺少其libc++依赖项。您可能需要使用

set\u target\u properties

来设置该位置。我们使用的是android studio。你能澄清一下我们应该使用什么命令以及应该链接什么吗？我想是你写的

CMakeLists.txt

；您应该使用

set_target_属性（导入的caffe2属性_LINK_依赖的_库[libc++.so或.a的路径]

。基本上是构建的

/home/augustinas/Android/Sdk/ndk bundle/sources/cxx stl/llvm libc++/

库的路径，无论它放在哪里。不。错误仍然在这里。你还有什么建议吗？完整输出：你似乎仍然在混合

libgnustl\u共享。因此

与

libc++\u static.a

。你的一些静态库使用其中一个或另一个进行重新构建，这就是链接步骤失败的原因。我在CMake调用的任何地方都看不到此选项

-DANDROID\u STL=gnustl\u shared

（由post建议）；您是否清理了CMake缓存？
