【Openwrt】开发环境搭建编译openwrt源码 - 谷动谷力

This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (casesensitive filesystem required). Cygwin is unsupported because of the lackof a case sensitive file system.
You need gcc, binutils, bzip2, flex, python3.5+, perl, make, find, grep, diff,unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
1. Run "./scripts/feeds update -a" to obtain all the latest package definitionsdefined in feeds.conf / feeds.conf.default
2. Run "./scripts/feeds install -a" to install symlinks for all obtainedpackages into package/feeds/
3. Run "make menuconfig" to select your preferred configuration for thetoolchain, target system & firmware packages.
4. Run "make" to build your firmware. This will download all sources, buildthe cross-compile toolchain and then cross-compile the Linux kernel & allchosen applications for your target system.

Openwrt开发环境搭建

阅读README内容，openwrt开发环境安装依赖工具链以及库：gcc, binutils, bzip2, flex, python3.5+, perl, make, find, grep, diff,unzip, gawk, getopt, subversion, libz-dev 和 libc

安装库以及工具链（依我的经验多加了一些）
sudo apt-get update
sudo apt-get install git g++ make libncurses5-dev subversion libssl-dev gawk libxml-parser-perl unzip wget python xz-utils vim zlibc zlib1g zlib1g-dev build-essential ccache gettext xsltproc flex patch asciidoc binutils bzip2 bison autoconf sharutils ncurses-term
如果是 64 位操作系统，需要多操作如下步骤：（注意libc6:i386 libncurses5:i386 libstdc++6:i386 中间要加冒号）
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386

编译openwrt源码

阅读README，有步骤1.2.3.4.共四步。这四步就是openwrt源码的编译步骤。

如下

1、更新源码包

$ ./scripts/feeds update -a

3、编译配置

$ make menuconfig

可能会出错

Build dependency: Please install the GNU C++ Compiler (g++). //安装 gcc g++ 如果要编译ARM平台需要arm-linux-gcc

Build dependency: Please install ncurses. (Missing libncurses.so or ncurses.h) //安装ncurese

Build dependency: Please install zlib. (Missing libz.so or zlib.h) //安装zlib

Build dependency: Please install GNU awk. www.2cto.com //sudo apt-get install gawk 注意名称

Build dependency: Please install flex. //安装flex

Build dependency: Please install patch. //安装pathc

Build dependency: Please install git (git-core). //安装git

Build dependency: Please install the subversion client. //安装subversion client

环境检测通过的话，运行到这步的时候会出现openwrt的配置界面

各种参数即可通过这里设置。

将Target Profile 设置为可支持硬件板子

  1. Multiple devices (TARGET_MULTI_PROFILE) //多种硬件
2. Broadcom SoC, BCM43xx WiFi (b43, brcmfmac, default) (TARGET_bcm53xx_generic_Generic) //博通的Soc

市场上路由基本上用OpenWrt做的。

我的开发板是MT7628的选择
MediaTek Ralink MIPS(MTK MIPS)

Subtarget(MT76x8 base boards)

选择Package the OpenWrt-base Toolchain是为了有搭建交叉编译环境方便，不是必选的。
Target System (MediaTek Ralink MIPS) --->
      Subtarget (MT76x8 based boards) --->
            Target Profile (Jotale JS76x8 16M)
LuCI  --->
      1. Collections  --->
            <*> luci................... LuCI interface with Uhttpd as Webserver (default)

此外，勾选LuCI(网页形式的控制台)还是非常必要的。要勾选(前面出现*号)：

最后Save，退出。

以上是基本的固件编译，如果需要其他功能，要再勾选或添加。

4、最后 make 编译

$ make -j10

编码出错了，

package/utils/busybox/Makefile' has a dependency on 'libpam', which does not exist
不写了，解决问题后，下回写吧

(编译出错是正常的，后面会相关总结，每次编译出错，我都会记录下来）
