请帮助解决这些错误.由于这些错误/警告，编译将终止.
Please help to fix these errors. Due to these errors/warnings compilation is getting terminated.
注意: 即使发生这些错误，也会创建Android目录.但是我认为由于上述错误，库无法正确编译.
Note: Android directory is getting created even after these errors. But I think library is not compiled properly due to above errors.
让我知道是否还有其他需要.请帮忙.
Let me know if anything else needed. Please help.
推荐答案
Your build script is out of date and not compatible with modern NDKs (it doesn't follow https://android.googlesource.com/platform/ndk/+/master/docs/UnifiedHeaders.md#supporting-unified-headers-in-your-build-system).
我建议您省些麻烦，并使用独立工具链为您处理组织事务.
I'd recommend saving yourself some trouble and using a standalone toolchain to handle the organizational bits for you.
