使用Tensorflow C++；在Android中使用CMake 我有Android应用程序，C++代码与CMake链接。我需要在C++侧加载和运行TysFraceFrand。 我使用./Tensorflow/contrib/makefile/build\u all\u android.sh脚本构建了Tensorflow。 我通过以下方式将tensorflow头文件和库添加到CMake文件中： # other libraries here add_library(lib_tf STATIC IMPORTED ) set_target_properties(lib_tf PROPERTIES IMPORTED_LOCATION /home/hhov/github/tensorflow/tensorflow/contrib/makefile/gen/lib/android_armeabi-v7a/libtensorflow-core.a) add_library(lib_proto STATIC IMPORTED ) set_target_properties(lib_proto PROPERTIES IMPORTED_LOCATION /home/hhov/github/tensorflow/tensorflow/contrib/makefile/gen/protobuf_android/armeabi-v7a/lib/libprotobuf.a) add_library(lib_proto_lite STATIC IMPORTED ) set_target_properties(lib_proto_lite PROPERTIES IMPORTED_LOCATION /home/hhov/github/tensorflow/tensorflow/contrib/makefile/gen/protobuf_android/armeabi-v7a/lib/libprotobuf-lite.a) add_library(lib_protoc STATIC IMPORTED ) set_target_properties(lib_protoc PROPERTIES IMPORTED_LOCATION /home/hhov/github/tensorflow/tensorflow/contrib/makefile/gen/protobuf_android/armeabi-v7a/lib/libprotoc.a) target_include_directories(pitools PRIVATE # Other header paths here ../../../../../../tensorflow/ ../../../../../../tensorflow/tensorflow/contrib/makefile/downloads ../../../../../../tensorflow/tensorflow/contrib/makefile/downloads/eigen ../../../../../../tensorflow/tensorflow/contrib/makefile/downloads/protobuf/src ../../../../../../tensorflow/contrib/makefile/gen/proto ../../../../../../tensorflow/tensorflow/contrib/makefile/downloads/nsync/public/ ../../../../../../tensorflow/tensorflow/contrib/makefile/gen/proto/ ) target_link_libraries( # Specifies the target library. #other libs here lib_tf lib_proto lib_proto_lite lib_protoc )

目前我只是尝试创建NewSession并加载图表。目前代码很简单： 包括此标题

#include "tensorflow/core/framework/tensor.h"
#include "tensorflow/core/public/session.h"
#include "tensorflow/core/util/stat_summarizer.h"

并创建了如下会话：

tensorflow::SessionOptions options;
options.config.set_inter_op_parallelism_threads(0);
options.config.set_use_per_session_threads(false);
options.config.set_intra_op_parallelism_threads(0);
options.config.set_allow_soft_placement(false);
options.config.set_log_device_placement(false);
tensorflow::Status status = tensorflow::NewSession(options, &_session);

当我尝试在Android Studio中创建项目时，会出现如下链接器错误：

tensorflow::SessionOptions options;
options.config.set_inter_op_parallelism_threads(0);
options.config.set_use_per_session_threads(false);
options.config.set_intra_op_parallelism_threads(0);
options.config.set_allow_soft_placement(false);
options.config.set_log_device_placement(false);
tensorflow::Status status = tensorflow::NewSession(options, &_session);

上述命令的错误为：

完整错误消息的Google驱动器链接：

你能告诉我我做错了什么，或者如果这不是正确的方法，那么你能提供一些步骤如何做到这一点吗

谢谢，

请在问题帖子中添加错误消息（以文本形式）。如果发现完整生成日志太长，请添加至post至少第一条错误消息。链接器错误看起来像是缺少STL。尝试将

set（CMAKE_CXX_FLAGS“${CMAKE_CXX_FLAGS}-std=c++11”）

添加到您的CMAKE脚本中。@Tsyvarev我添加了第一条错误消息。@JamesPoag我这样设置它：set（CMAKE_CXX_FLAGS“${CMAKE_CXX_FLAGS}-std=c++14-fexceptions-frti-ffast math-Wno showing-O3”）
