Getting error when trying to run gemm code for ARM benchmark

[Aditya-Dev598]

I'm trying to rum the gemm code for ARM benchmark on NVIDIA Jetson TX2. these are the modifications that I made in the Makefile.

all: gemm conv sparse

BIN_DIR?=bin
EIGEN_PATH?=Eigen/Eigen
MKDIR=mkdir -p
ARM_COMPUTE_INCLUDE_PATH?=/usr/local/ARMComputeLib
ARM_COMPUTE_LIB_PATH?=/usr/local/ARMComputeLib/
ARM_COMPUTE_LIB=$(ARM_COMPUTE_LIB_PATH)/lib/linux-arm64-v8a-neon
KERNELS_DIR=../kernels/

gemm: gemm_bench.cc
$(MKDIR) $(BIN_DIR)
g++ -O3 --std=c++11 -I $(KERNELS_DIR) -lpthread -o bin/gemm_bench $<

When i run the command on the terminal.

nvidia@nvidia-desktop:~/Downloads/DeepBench-master/code/arm$ ./run_gemm_bench.sh

This is the error that I got

fatal: not a git repository (or any of the parent directories): .git
mkdir -p bin
g++ -O3 --std=c++11 -I ../kernels/ -lpthread -o bin/gemm_bench gemm_bench.cc
gemm_bench.cc:6:10: fatal error: gemmlowp/public/gemmlowp.h: No such file or directory
#include "gemmlowp/public/gemmlowp.h"

make: *** [gemm] Error 1

./run_gemm_bench.sh: line 8: bin/gemm_bench: No such file or directory

It will be grateful if anyone can help me out.

Just to add in the CPU I'm using is ARM-Cortex57

Basically gemmlowp library is missing which we need to link externally.

To do so git clone the below repository
$ git clone https://github.com/google/gemmlowp.git

Once done open gemm_bench.cc file and specific the path of gemmlowp folder which is cloned
In my case it was under my home directory
i.e #include "/home/harikesh/gemmlowp/public/gemmlowp.h"

This should work and you'll be able to build gemm_bench kernel.
