准备工作
1. 安装依赖软件
这是提供的依赖列表
yum install subversion binutils bzip2 gcc gcc-c++ gawk gettext flex ncurses-devel zlib-devel zlib-static make patch unzip perl-ExtUtils-MakeMaker glibc glibc-devel glibc-static quilt ncurses-libs sed sdcc intltool sharutils bison wget git-core openssl-devel xz
除此以外, 建议加上 glib2-devel
2. 编译升级gcc
Centos6自带的gcc版本只到4.4.7, 不支持c++11, 必须升级. 参考 升级到gcc 6.4.0
3. 导出最新源码
例如在home下的用户目录下, 新建一个lede目录, 然后在此目录下执行, 然后将source目录更名为 source_master
git clone https://git.lede-project.org/source.git
注意: 编译将在此目录下执行, 根据官方文档的要求, 路径中要避免出现空格等特殊字符, 以免编译失败
Update 2018-08-12 LEDE与原OpenWRT合并后, 代码主干URL变成了
git clone https://git.openwrt.org/openwrt/openwrt.git/
切换到tag:
$ git tag$ git checkout -b v18.06.1 v18.06.1
配置工作
1. 当git代码库有更新时, 更新源码
git pull
2. 更新组件源
# 更新组件源./scripts/feeds update -a# 安装所有组件, 安装后, 在make menuconfig中才可以选择./scripts/feeds install -a# 安装指定组件./scripts/feeds install
Update 2018-08-12: 在编译 v18.06.0 时, 出现了 time checking failed的错误
...Checking 'wget'... ok.Checking 'time'... failed.Checking 'perl'... ok....Build dependency: Please install GNU 'time' or BusyBox 'time' that supports -f
经检查, 检查语句是
$ grep -rnw './' -e 'that supports -f'./include/prereq-build.mk:141:$(eval $(call SetupHostCommand,time,Please install GNU 'time' or BusyBox 'time' that supports -f, \$ more include/prereq-build.mk $(eval $(call SetupHostCommand,time,Please install GNU 'time' or BusyBox 'time' that supports -f, \ gtime --version 2>&1 | grep GNU, \ time --version 2>&1 | grep GNU, \ busybox time 2>&1 | grep -- '-f FMT'))
而 time 命令是bash shell内建的, 无法更改, 故下载了最新版的gnu time编译安装并ln -s为 gtime 命令, 这样检查就通过了
$ wget https://ftp.gnu.org/gnu/time/time-1.9.tar.gz$ tar zxvf time-1.9.tar.gz$ ./configure$ make$ sudo make install $ ln -s /usr/local/bin/time /usr/bin/gtime
3. 设置编译目标设备以及包含的组件, 主要是两个命令
# 重置默认的设备和组件make defconfig# 进入配置界面make menuconfig
使用make menuconfig时, 需要注意的
- 常用的mt7620/7621芯片所属的target位于 Target System -> MediaTek Ralink MIPS
- 设置之后, 除了save到.config_[device name]以外, 还需要设置到.config, 否则编译时因为.config没变, 你的设置不会生效
Update 2018-11-23:
在make menuconfig之后在开始编译之前, 现在增加了一个步骤, 在编译前进行下载
# download all dependency source files before final make, enables multi-core compilation);make download
开始编译
1. 执行编译命令行
make -j2 V=s TARGET_DEVICES=hc5761# -j2 表示用2核, 根据当前机器配置而定# V=s 表示显示详细输出
2. 如果需要后台进行, 使用
nohup make -j2 V=s TARGET_DEVICES=hc5761 > ~/lede/logs/20171011.log 2>&1 &
Updated 2018-08-12: 编译v18.06.0, 会出现"b2a_base64() argument 1 must be string or read-only buffer, not bytearray" 错误, 经google查询发现这是python2.6的一个bug, 在python2.7以后已经修复, 但是在Centos6.8下, 多次尝试包括编译安装python2.7并alias python到python2.7依然无法将默认的python环境改为2.7, 最后放弃Centos6, 重建Centos7虚机进行编译
遇到的问题
1. 编译时因网络问题下载失败
自行下载文件后放到dl目录下
2. 编译transmission时出现 config.status: error: cannot find input file: `po/Makefile.in.in' 错误
这是因为没安装glib2-devel
设备测试
1. 极路由二 HC5761
使用 r5040-f98f83e版本代码编译, 工作正常 问题: 除了5GHz的wlan. 在目前的kernel 4.9.x 上尚未找到解决办法.2. 小米路由MINI
使用 r5040-f98f83e版本代码编译, 工作正常3. NeWiFi D1
使用 r5040-f98f83e版本代码编译, 工作正常 问题: 不能软重启(即在Luci界面或命令行通过reboot重启), 经查是因为32M flash带来的问题, 可以通过补丁修复, 不过无所谓了...
Update 2018-08-02:
NeWiFi D1不能reboot的原因是其闪存MX25L25635F被系统当成了MX25L25635E来处理, MX25L25635F是支持无状态4字节读写的, 但是MX25L25635E不支持. 因为这两个型号使用的是同样的硬件ID, 所以系统无法区分.
: "The Newifi D1 has most likely a MX25L25635**F**. But the MX25L25635E and MX25L25635F share the same "hardware id" 0xc22019, therefore can't be distinguished and are handled as MX25L25635E by the kernel. The MX25L25635F supports stateless 4-byte read and write (you can use SPI_NOR_4B_OPCODES). Where the MX25L25635E does **not** support any stateless 4-byte command."
对应的补丁在 . 补丁修改的是 drivers/mtd/spi-nor/spi-nor.c 文件.

把make menuconfig里面勾选的自定义项都记录一下
