Question

我正在尝试为运行the building script的Android编译tensorflow-lite，但构建过程因此错误而停止：

/system/bin/linker: No such file or directory

我可以理解构建过程是如何工作的（compilation + linking）但我无法弄清楚为什么这个＆＃39; / system / bin / linker＆＃39;需要。此链接器不存在于SDK或NDK文件夹中，并且它不存在于主机的文件夹树中（我使用Linux进行构建过程）。

它看起来像Android文件结构的一部分，但构建过程不应该依赖于最终的系统结构。

我想要构建的元素是＆＃39; schema_fbs＆＃39;，它使用flatbuffers（第三方依赖项）编译部分代码。我正在使用的完整句子是：

bazel build \
--cxxopt='--std=c++11' \
--crosstool_top=//external:android/crosstool \
--host_crosstool_top=@bazel_tools//tools/cpp:toolchain \
--cpu=armeabi-v7a \
--verbose_failures \
--subcommands \
//tensorflow/contrib/lite/schema:schema_fbs

这可能是由Bazel构建脚本中的测试用例引起的（我已经评论了我发现的所有测试），但为什么需要链接器呢？我有什么必须做的来定义这个系统＆＃39;编译过程中的文件夹？

注意：

目标操作系统：Android

主机操作系统：Ubuntu 16.04

使用NDK：v16b（使用v17测试但不兼容）

TensorFlow Lite AAR也可以使用以下方式构建：

{{1}}

并且您必须确保运行./configure并让它为您配置SDK和NDK。

＆＃34; / system / bin / linker：没有这样的文件或目录＆＃34;尝试编译TensorFlow时出错
