【寒武纪硬件产品型号】必填*：MLU220

【使用操作系统】必填*：Linux ubuntu 4.15.0-142-generic #146~16.04.1-Ubuntu SMP Tue Apr 13 09:27:15 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

【使用驱动版本】必填*： v4.9.4

【使用AI框架】必填*：BANG语言

【出错信息】必填*：执行/usr/local/neuware/samples/BANG下的build.sh，大量报错，错误信息见日志

error_log.txt

【操作步骤】选填：修改并执行./env.sh，仅仅删除了TOOLCHAIN_ROOT，没有其他修改。该文件内容如下：
if [ -z "${NEUWARE_HOME}" ]; then
  export NEUWARE_HOME=/usr/local/neuware
fi
if [ -z "${TOOLCHAIN_ROOT}" ]; then
  export TOOLCHAIN_ROOT="" # 已经配置好交叉编译工具，工具正常使用
fi

export PATH=${NEUWARE_HOME}/bin:${PATH}
export LD_LIBRARY_PATH=${NEUWARE_HOME}/lib64:${LD_LIBRARY_PATH}
export LD_LIBRARY_PATH=${NEUWARE_HOME}/lib:${LD_LIBRARY_PATH}

已修改build.sh，仅仅修改了CPU架构：TARGET_CPU_ARCH="aarch64-linux-gnu"和任务并行：make -j6：

#!/bin/bash
set -e

source env.sh

check_deb_package() {
    if [ -z "$(dpkg -l | grep ${1})" ]; then
        echo "Please sudo apt install ${1}"
        exit -1
    fi
}

check_rpm_package() {
    if [ -z "$(rpm -qa | grep ${1})" ]; then
        echo "Please sudo yum install ${1}"
        exit -1
    fi
}

# check dependency for build
if [ -f "/etc/os-release" ]; then
    source /etc/os-release
    if [ ${ID} == "ubuntu" ] || [ ${ID} == "debian" ]; then
        check_deb_package cmake
        check_deb_package ccache
        CMAKE=cmake
    elif [ ${ID} == "centos" ]; then
        check_rpm_package cmake3
        check_rpm_package ccache
        CMAKE=cmake3
    else
        echo "Not support build on this os!"
        exit -1
    fi
fi

export WORKSPACE=${PWD}
