runtime-error - 在针对 ARM 64 架构交叉编译的 android 上运行 Tf 项目的可执行文件时出错

Question

我正在开发一个 TensorFlow-lite 解决方案，以部署在 ARM-64 架构上。我使用 android ndk 独立工具链交叉编译了我们的 C 代码。我包含了编译所需的所有库，并在编译时成功获得了一个 out.exe 文件和一个 out.so 文件。但是在尝试在具有 arm64 架构的 android 手机上运行 .exe 文件时（使用 adb shell 环境并推送编译期间使用的所有必需库和 out.so 获得）它给出了空指针取消引用错误。这是执行.exe文件后在cmd上得到的错误日志——

WARNING: linker: Warning: "/data/snd/NC2/libtensorflowlite_c.so" unused DT entry: DT_RPATH (type 0xf arg 0xf68) (ignoring)

这是获得的日志文件 -

我为交叉编译包含的库列表是 - libtensorflowlite_c.so、libpthread.so.0、ld-linux-aarch64.so.1、libc.so.6 libc++.so、libdl.so.2、libm.so .6、librt.so.1、libstdc++.so.6、libgcc_s.so.1。（所有这些库都将 Linux 作为操作系统，将 arm64 作为要部署的架构）。
