• 标题： building optimize tool fails with script for RPi 5 and RPi4
• 版本、环境信息：    1）Paddle Lite 版本：v2.13-rc    2）Host 环境：Debian Bookworm    3）运行设备环境：Raspberry Pi 5    4）预测后端信息：CPU (ARM Cortex-A76)
• 复现信息：如为报错，请给出复现环境、复现步骤
• 问题描述： When using the script to build the optimizer for the Raspberry Pi 5 you face two issues.

1. The latest gcc version 12.2 fails to compile the provide third-party protobuf.

To address this issue, add const at the end of line 68 in

thrid-party/protobuf-host/src/google/protobuf/compiler/java/java_file.cc

2. The build_linux.sh script is hard coded and fixed for an x86 machine. When running the script, you get the following output on the terminal:

-- LITE_WITH_X86: ON -- LITE_WITH_ARM: OFF -- LITE_WITH_SW: OFF -- LITE_WITH_OPENCL: OFF -- LITE_WITH_METAL: OFF -- LITE_WITH_XPU: OFF -- LITE_WITH_NNADAPTER: OFF -- LITE_WITH_PROFILE: OFF -- LITE_WITH_CV: ON

You need to alter the script to get it working for the Raspberry Pi (or any other aarch64 device other than Android). Inside build_linux.sh

# 4.2 function of opt
function build_opt {
    rm -f $workspace/lite/api/paddle_use_ops.h
    rm -f $workspace/lite/api/paddle_use_kernels.h
    prepare_thirdparty

    build_dir=$workspace/build.opt
    rm -rf $build_dir
    mkdir -p $build_dir
    cd $build_dir
    cmake $workspace \
      -DARM_TARGET_OS=armlinux \
      -DLITE_ON_MODEL_OPTIMIZE_TOOL=ON \
      -DWITH_TESTING=OFF \
      -DLITE_WITH_X86=OFF \
      -DLITE_WITH_ARM=ON \
      -DLITE_BUILD_EXTRA=ON \
      -DWITH_MKL=OFF
    make opt -j$NUM_PROC
}

Now you get -- LITE_WITH_X86: OFF -- LITE_WITH_ARM: ON -- LITE_WITH_SW: OFF -- LITE_WITH_OPENCL: OFF -- LITE_WITH_METAL: OFF -- LITE_WITH_XPU: OFF -- LITE_WITH_NNADAPTER: OFF -- LITE_WITH_PROFILE: OFF -- LITE_WITH_CV: ON

感谢，确实有这个问题
