OpenWrt下载编译以及在VMWare上运行

本文记录以下OpenWrt的入门知识，包括源码编译，make menuconfig配置，feeds包下载以及生成可以运行在VMWare上的镜像。

然后在VMWare上运行，并配置静态IP，然后可以使用SSH工具远程连接到OpenWrt系统中。

更新下载feeds

会将每个feed下载到feeds/<feed_name>目录下，同时创建相应的feeds/<feed_name>.tmp目录存放索引文件、下载路径（location）等

每个feed具有一个索引文件，索引文件中保存了feed下每个软件包的详细信息（软件包名、版本号、使用的Makefile、依赖关系等等），示例如下：

blduan@ubuntu24:~/projects/open_source/openwrt/feeds/packages.tmp$ more .packageinfo

Package: atop
Version: 2.11.0-r2

Description:   Atop is an ASCII full-screen performance monitor for
  Linux that is capable of reporting the activity of all
  processes (even if processes have finished during the
  interval), daily logging of system and process activity
  for long-term analysis, highlighting overloaded system
  resources by using colors, etcetera. At regular
  intervals, it shows system-level activity related to the
  CPU, memory, swap, disks (including LVM) and network
  layers, and for every process (and thread) it shows e.g.
  the CPU utilization, memory growth, disk utilization,
  priority, username, state, and exit code. In combination
  with the optional kernel module netatop, it even shows
  network activity per process/thread.

安装feeds

这些feed在安装前其软件包在OpenWrt构建时是不被包含在内的。

安装过程则是将这些软件包软链接到package目录下，之后则可以通过make package/feeds/<feed_name>/<package_name>/compile进行构建，同时也能够在make menuconfig中看到。

编译配置

配置Target X86：

配置Target Image（VMDK）：

配置Web UI：

配置完成之后会在代码根目录生成.config文件。

blduan@ubuntu24:~/projects/open_source/openwrt$ ls -l .config
-rw-rw-r-- 1 blduan blduan 261986 Nov 23 04:02 .config
blduan@ubuntu24:~/projects/open_source/openwrt$ cat .config | grep X86
CONFIG_FFMPEG_X86ASM=y
blduan@ubuntu24:~/projects/open_source/openwrt$ cat .config | grep VMDK
CONFIG_VMDK_IMAGES=y

下载开源组件

截至到这儿为止，所有的软件包的源码都还没有下载到本地，下载信息则保存在对应软件包的Makefile文件中。因此，接下来首先要将软件包的源码下载到本地。

至于具体要下载哪些软件包，则取决于是否在make menuconfig是否配置。

软件包的源码会下载到dl目录，同时会解压到build_dir/target*目录下

可以使用命令make download -j$(nproc) V=s进行下载。

开始编译

编译命令：make -j$(nproc) V=s

编译完成之后的目录结构：其中bin, build_dir, staging_dir, tmp是编译产生的，并且编译的镜像在bin目录下。
