Error when trying to build .so file from TFlite C++ API

ODT_novice · August 22, 2023, 2:21am

Hi,
I tried to build my own C++ shared libraries on Windows, but encountered some Bazel build errors.
My Android NDK version is 21.1.6352462, Bazel version is 6.3.2.
Here is my configure setting:

Would you like to interactively configure ./WORKSPACE for Android builds? [y/N]: y
Please specify the (min) Android NDK API level to use.:21
Please specify the Android SDK API level to use.:31
Please specify an Android build tools version to use.:33.0.0

I have tried the following two build commands:

bazel build -c opt --config=android_arm //tensorflow/lite:libtensorflowlite.so
bazel build -c opt --config=android_arm64 //tensorflow/lite:libtensorflowlite.so

But I keep getting this error:

Clang error: No such file or directory: /d2ReducedOptimizeHugeFunctions

d2ReducedOptimizeHugeFunctions is an option for Windows build.

tensorflow/tensorflow/blob/master/.bazelrc#L334


      
          build:windows --copt=/D_USE_MATH_DEFINES
          build:windows --host_copt=/D_USE_MATH_DEFINES
          
          
# Windows has a relatively short command line limit, which TF has begun to hit.

# Enable the runfiles symlink tree on Windows. This makes it possible to build
          # the pip package on Windows without an intermediate data-file archive, as the
          # build_pip_package script in its current form (as of Aug 2023) uses the
          # runfiles symlink tree to decide what to put into the Python wheel.
          startup:windows --windows_enable_symlinks
          build:windows --enable_runfiles
          
          
# Default paths for TF_SYSTEM_LIBS

Are you using Windows? Does it work if you remove those lines?

Hi Terry_Woncheol_Heo,
Thank you for your reply.
Yes, I build the library on windows, and I attempted to comment out these two lines of code in .bazelrc.

build:windows --copt=/d2ReducedOptimizeHugeFunctions
build:windows --host_copt=/d2ReducedOptimizeHugeFunctions

The same error still persists.
