OpenWrt编译环境搭建

发布时间 2023-11-28 11:57:18作者: 付时凡

OpenWrt编译环境搭建

  1. 基于Ubuntu 22.04，64bit的操作系统

  2. 先clone仓库：

    git clone https://git.openwrt.org/openwrt/openwrt.git

    可能会比较久，取决于网络状况。笔者是23年Q4写的，此时openwrt已经为v23了。

    clone成功后，会在clone的路径下有openwrt的文件夹。

  3. 进入文件夹：

    cd openwrt

    更新软件包：

    ./scripts/feed update
./scripts/feed install

    后续有需要，也可以手动再更新。

  4. 生成配置文件：

    make defconfig

    这一步和电脑安装软件的情况有关。可能会有报错，此时需根据报错日志来判断安装软件，如：

    sudo apt-get install git

    建议有报错后再安装即可，没必要一次性安装推荐的所有软件，浪费电脑磁盘。

  5. 进入定制页面：

    make menuconfig

    通过键盘的上下方向键选择机型，包括CPU等，通过空格键选中，保存并退出。

    如果有需要定制的package，也可以在这一步操作，如可以参考笔者的：

    OpenWrt源码编译新增项 - 付时凡 - 博客园 (cnblogs.com)

  6. 编译：

    make -j4 V=sc
    • -j4表示使用4核编译，如果电脑的CPU比较强，则推荐。当然，第一次编译，建议先不用该参数，单核编译，出错率会少一些
    • V=sc表示输出更多的报错日志，方便debug，例如是否是download某些源文件失败等，如果是download失败，可能是国内网络环境受限，可通过报错日志中的URL等信息，手动下载对应的压缩包文件，放在dl目录下，然哦胡重新编译即可

  7. 附完整编译日志，笔者这里是编译时不带V=sc参数，芯片方案为高通的ipq40xx：

 make[2] json_overview_image_info
 make[2] checksum

    后续这些便是可选的编译目标，例如需要单独编译procd，则：

    make package/system/procd compile

  8. 编译后的镜像文件在bin目录下，如笔者的为：

    bin/targets/ipq40xx/generic/

  9. 说明下几个镜像：

    镜像 说明 备注
    initramfs-recovery.itb itb固件，并且带initramfs，即可以进入uboot，直接通过加载该镜像启动，如：bootm xxx.initramfs-recovery.itb 通常可用于测试固件是否正常，此时uboot启动，并不会破坏原有的FW分区等数据
    squashfs-factory.ubi 带factory字样，一般会覆盖旧有的配置，如第一次刷机
    squashfs-sysupgrade.bin 即经过刷机后的可通过openwrt页面直接升级的FW 在刷机稳定后，通过此固件升级；如果已经是openwrt固件，即可直接通过web升级该固件
