build issue

[alighofrani95]

Thanks for the great repo.

I follow step by step and the mediapipe hand tracker sample works fine on both cpu and gpu but by running ./build_prediction.sh
I faced with the error below.
How could I solve this?

ERROR: /.cache/bazel/_bazel/c6c43a719d1d619ea377f6e06c7a462c/external/mediapipe/mediapipe/util/tflite/BUILD:89:11: C++ compilation of rule '@mediapipe//mediapipe/util/tflite:tflite_gpu_runner' failed (Exit 1) gcc failed: error executing command /usr/bin/gcc -U_FORTIFY_SOURCE -fstack-protector -Wall -Wunused-but-set-parameter -Wno-free-nonheap-object -fno-omit-frame-pointer -g0 -O2 '-D_FORTIFY_SOURCE=1' -DNDEBUG -ffunction-sections ...

Hi @alighofrani95,
thanks for your request.
Could you please provide your system specs, operating system and bazel version?

[alighofrani95]

Bazel version is 3.4.1 and the OS is Ubuntu 20.04

Thank you. We have made the experience that it doesn't work with Ubuntu 20.04. Unfortunately we do not know why. Please try it with Ubuntu 18.04.
