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.

github.com

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

          build:linux --copt="-Wno-array-bounds"
          
          # Add unused-result as an error on Linux.
          build:linux --copt="-Wunused-result"
          build:linux --copt="-Werror=unused-result"
          # Add switch as an error on Linux.
          build:linux --copt="-Wswitch"
          build:linux --copt="-Werror=switch"
          # Required for building with clang
          build:linux --copt="-Wno-error=unused-but-set-variable"
          
          # Linux ARM64 specific options
          build:linux_arm64 --copt="-mtune=generic" --copt="-march=armv8-a" --copt="-O3"
          
          
          # On Windows, `__cplusplus` is wrongly defined without this switch
          # See https://devblogs.microsoft.com/cppblog/msvc-now-correctly-reports-__cplusplus/
          build:windows --copt=/Zc:__cplusplus

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.
