I can bulid a “dbg” so with symbols by:
bazel build -c dbg --strip=never --cxxopt=–std=c++11 --config=android_arm //tensorflow/lite/c:tensorflowlite_c

but when I change “-c dbg” to " -c opt --copt=’-g’ " , libtensorflowlite_c.so without symbols.
(bazel build -c opt --copt=‘-g’ --strip=never --cxxopt=–std=c++11 --config=android_arm //tensorflow/lite/c:tensorflowlite_c)

How can I get an opt so with symbols ?
(tensorflow 2.2, bazel 2.0)

Thank you very much.
