Ubuntu20.04下Braiins OS源码多方式构建失败求助

目前无法从源码构建Braiins OS。先后尝试了运行bb.py、遵循官方Docker构建指南操作、使用cargo编译bosminer、在firmware_latest和bos_release分支直接调用LEDE Makefile四种方式，所有方法均执行失败，出现的错误与异常信息如下：

1. 运行Docker构建器 #

参考操作指南为官方提供的构建文档

执行的命令 #

• cd braiins/braiins-os
• ./docker/build-docker-container.sh
• ./docker/build-in-docker.sh zynq-am1-s9

错误与异常信息 #

为简化日志内容，已移除执行成功的步骤，如有需要可提供完整日志。

已尝试的解决步骤 #

• 安装了lib32z1与libncurses5依赖，未解决问题

2. 运行bb.py构建 #

添加日志参数开启调试模式后，发现bb.py会调用位于zynq/lede路径下存在问题的Makefile。

执行的命令 #

• python3.5 bb.py --log debug build

3. 手动调用LEDE Makefile #

通过bb.py的--log debug参数确认braiins/braiins-os/build/zynq/lede路径下的Makefile执行异常，因此手动执行该Makefile查看详细日志。

执行的命令 #

• cd braiins/braiins-os/build/zynq/lede
• make -j1 V=s

错误与异常信息 #

已尝试的解决步骤 #

• 安装了m4尝试解决freadahead.c报错，未生效

4. 使用cargo构建Rust组件 #

不指定编译目标时，Rust代码可在本地机器正常编译，但指定目标为arm-unknown-linux-musleabi时编译完全失败。

执行的命令 #

• 下载了arm-linux-musleabihf-cross交叉编译工具链
• CC=/home/max/Downloads/arm-linux-musleabihf-cross/bin/arm-linux-musleabihf-gcc cargo build --release --target arm-unknown-linux-musleabi

错误与异常信息 #

error: linker `arm-openwrt-linux-muslgnueabi-gcc` not found
  |
  = note: No such file or directory (os error 2)

error: could not compile `bosminer-erupter` due to previous error
warning: build failed, waiting for other jobs to finish...
error: build failed

运行环境 #

• OS: Ubuntu 20.04.3 LTS
• cargo: cargo 1.60.0 (d1fd9fe 2022-03-01)
• rustup: rustup 1.24.3 (ce5817a94 2021-05-31)
• python: Python 3.5.6 :: Anaconda, Inc.

所有报错归因为三个核心问题：官方Docker镜像版本过旧与新宿主系统不兼容、LEDE内置源码版本与高版本GCC不兼容、Rust交叉编译链接器配置不匹配，按以下步骤操作即可全部解决：

修复Docker构建依赖问题 #

官方默认构建脚本生成的镜像基于低版本Ubuntu，缺少GLIBC_2.27和libncursesw6依赖，直接修改Docker配置即可：

1. 打开docker/Dockerfile，将基础镜像替换为ubuntu:20.04
2. 在依赖安装列表中添加libc6、libncursesw6两个包，保留原有python3.5、编译工具链等依赖
3. 重新构建Docker镜像后再执行容器内构建脚本，即可解决GLIBC版本不匹配、libncursesw.so.6缺失的报错

修复本地LEDE编译的m4报错 #

freadahead.c报错是因为LEDE内置的m4 1.4.17版本与GCC 9及以上版本不兼容，安装系统级m4无法解决该问题，需要替换LEDE编译链使用的m4版本：

1. 进入braiins/braiins-os/build/zynq/lede/tools/m4目录
2. 修改目录下的Makefile，将PKG_VERSION字段值从1.4.17改为1.4.19，同步更新PKG_HASH为m4 1.4.19版本对应的官方校验值
3. 删除build_dir/host目录下残留的m4-1.4.17旧源码目录，重新执行编译即可跳过该报错
   注意：本地编译不要使用Anaconda虚拟环境，Anaconda自带的旧版GLIBC会干扰LEDE构建工具链的运行，切换到系统原生Python 3.5环境执行bb.py即可

修复Rust交叉编译链接器报错 #

该报错是因为cargo的目标架构配置默认查找OpenWrt命名规则的交叉编译器，和已下载的musl工具链命名不匹配，不需要额外找对应名称的编译器，直接修改cargo配置即可：

1. 在项目根目录新建.cargo/config.toml文件
2. 在文件中添加以下配置，将链接器路径替换为本地实际的工具链gcc路径：

[target.arm-unknown-linux-musleabi]
linker = "/home/max/Downloads/arm-linux-musleabihf-cross/bin/arm-linux-musleabihf-gcc"

3. 保存配置后重新执行cargo构建命令即可正常编译。
