System Setup :

OS: Windows 10 QT version: 5.14.1 QT MinGW version : mingw73_64 CMake version : 3.22 MSVC verison : 2019 (14.29.30133) Tensorflow verison : latest master(https://github.com/tensorflow/tensorflow/commit/7a896053528d69c46ec076a6602b7d693ca5108d) Bazel version: 5.0.0

How I compiled tflite dll and lib:

  • clone TensorFlow repo
  • install bazel and set environment variables for BAZEL_VC
  • compile using command bazel build --cxxopt=--std=c++14 -c opt //tensorflow/lite:tensorflowlite --verbose_failures
  • genarated 3 files tensorflowlite.dll, tensorflowlite.dll.if.lib, flatbuffers.lib
  • link this file in my .pro file as follows.
LIBS += -L$$MSVC_PATH/lib \
-L"E:/MergingSpace/GCSObjectDetection/tensorflow/bazel-bin/tensorflow/lite/tensorflowlite.dll" \
-L"E:/MergingSpace/GCSObjectDetection/tensorflow/bazel-bin/tensorflow/lite/tensorflowlite.dll.if.lib" \            
-L"E:/MergingSpace/GCSObjectDetection/tensorflow/bazel-bin/external/flatbuffers/src/flatbuffers.lib" \

INCLUDEPATH += $$PWD/include \
$$PWD/include/tensorflow \
$$PWD/tensorflow \
$$PWD/tensorflow/lite \
$$PWD/tensorflow/tensorflow/lite/core \
$$PWD/tensorflow/third_party/fft2d \
$$PWD/tensorflow/tensorflow/core/platform \
$$PWD/tensorflow/tensorflow/core/util \                   
$$PWD/tensorflow/bazel-tensorflow/external/flatbuffers/include

Problem facing:

  • same code is compiled with Android and Linux and it is working good. but while compiling for windows its showing me the following errors.

    `-L` is for specifying library directories, don't add any prefix when specifying the full path to a library. Note that you can't link to a dll file – Alan Birtles Mar 11 '22 at 10:58
  • I tried all the possible ways but did not work any. also tried to add a library from the project context menu add an external library option. – 8-DK Mar 12 '22 at 09:16

    what exactly have you tried? Are you trying to mix libraries built with visual studio and gcc? that probably wont work – Alan Birtles Mar 12 '22 at 12:50
  • The issue is solved. The bazel compiles library with MSVC, but Qt compiler for my application set to mingw64. So I compile TensorFlow lite using CMake as a project in Qt creator with mingw64. Then link .a files in theLIBS. after getting some undefine variable error again, then I add some source and header files from ruy library to my application and that worked. – 8-DK Mar 14 '22 at 17:21
