I have been following the guide at https://www.tensorflow.org/lite/guide/build_arm in an attempt to compile TfLite for a Nvidia Jetson Nano. Following the instructions for the c++ install, I've installed Bazel and proceeded to build, only to get the following error:
ERROR: /home/user/tensorflow/tensorflow_src/tensorflow/lite/kernels/internal/BUILD:857:11: Compiling tensorflow/lite/kernels/internal/mfcc.cc failed: (Exit 2): aarch64-linux-gnu-gcc failed: error executing command

Checking the file where it exploded, this seems to be the line in question

cc_library(
name = "audio_utils",
srcs = [
"mfcc.cc",
"mfcc_dct.cc",
"mfcc_mel_filterbank.cc",
"spectrogram.cc",

hdrs = [

copts = tflite_copts(),
deps = [

But I have no idea why it would have an issue here in particular. This is an otherwise clean OS install. Any idea what might be causing this?
