[部分已解决] v853 sdk 编译失败：undefined reference to `sunxi_challenge`

duskmoon LV 2

2022-08-11 UPDATE:

官方 SDK 使用的 openwrt 版本略旧，无法使用 ubuntu 22.04 进行编译。降级为 ubuntu 20.04 补足依赖后成功编译，并未再遇到此错误。

buildroot 无法通过编译，可能也与版本有关，之后再研究吧

目前的docker：https://github.com/duskmoon314/dev-env

我在尝试搭建一个 docker image 用于编译 sdk
日常使用 mac，最近配置了一个 manjaro 用于开发，目标在这上面使用

docker image 基于 ubuntu:22.04，安装依赖如下：

apt install -y --no-install-recommends \
    git \
    ssh \
    ca-certificates \
    build-essential \
    iproute2 \
    iputils-ping \
    curl \
    wget \
    neovim \
    subversion \
    libncurses5-dev \
    zlib1g-dev \
    gawk \
    flex \
    quilt \
    libssl-dev \
    xsltproc \
    libxml-parser-perl \
    mercurial \
    bzr \
    ecj \
    cvs \
    unzip \
    lib32z1 \
    lib32z1-dev \
    lib32stdc++6 \
    libstdc++6 \
    python3 \
    python-is-python3 \
    xxd \
    # end of list

将容器运行并绑定 tina-v853-open 目录后，按照 buildroot 步骤进行编译：

执行命令都不是 root 用户，映射到系统的可以 sudo 的用户的

openwrt 也是类似的错误

希望有人帮忙看看我漏了什么 orz

buildroot不支持 ubuntu:22.04，只有 openwrt支持，buildroot最高支持ubuntu18.04

@yteraa 在 v853 sdk 编译失败：undefined reference to `sunxi_challenge` 中说：

buildroot不支持 ubuntu:22.04，只有 openwrt支持，buildroot最高支持ubuntu18.04

啊这，我换 ubuntu 20.04 试试

不过 openwrt 也会报 sunxi_challenge 的问题……

duskmoon LV 2

啊这，我换 ubuntu 20.04 试试

18.04 和 20.04 也有同样的错误，我觉得问题似乎不在于 ubuntu 版本

docker 的问题，sunxi_challenge是从urandom里出来的一个随机码，Makefile把@删了就可以了

CLEAN_FILES += board/sunxi/sunxi_challenge.c
board/sunxi/sunxi_challenge.c:
	echo "  prepare sunxi_challenge..."
	dd if=/dev/urandom of=sunxi_challenge bs=128 count=1 > /dev/null 2>&1
	xxd -c 8 -i sunxi_challenge > board/sunxi/sunxi_challenge.c
	sed -i '/^unsigned/i __attribute__((__used__))' board/sunxi/sunxi_challenge.c
	rm sunxi_challenge
prepare: board/sunxi/sunxi_challenge.c
