    1. 7.1. 作者的其它热门文章

本人是只菜鸟,没有接触过OpenWrt,只是平时都是在Linux下做开发。习惯了Linux的开发环境。

本人的操作系统是CentOS 6.4(好久都没有换过了)。本人按照网上牛人们的指点也开始下载编译OpenWRT。

如下为网上的资料:


sudo apt-get update (更新)
安装编译需要的组件:
sudo apt-get install gcc
sudo apt-get install g++
sudo apt-get install binutils
sudo apt-get install patch
sudo apt-get install bzip2
sudo apt-get install flex
sudo apt-get install bison
sudo apt-get install make
sudo apt-get install autoconf
sudo apt-get install gettext
sudo apt-get install texinfo
sudo apt-get install unzip
sudo apt-get install sharutils
sudo apt-get install subversion
sudo apt-get install libncurses5-dev
sudo apt-get install ncurses-term
sudo apt-get install zlib1g-dev
sudo apt-get install gawk
sudo apt-get install asciidoc
sudo apt-get install libz-dev

编译环境搭建完成
mkdir openwrt 创建一个openwrt文件夹
cd openwrt 进入openwrt文件夹
svn co svn://svn.openwrt.org/openwrt/branches/backfire 下载官网的源码
./scripts/feeds update -a 更新软件包
./scripts/feeds install -a 安装软件包
make menuconfig 进入定制界面(里面可以选择芯片的型号,集成的组件等等,根据实际情况选择)
defconfig
make V=99 (开始编译)
剩下的就是等待了,第一次编译需要的时间相对比较长,这个跟你的电脑配置和网速有关。


由于原作者是用的Ubuntu作为开发环境,所以在安装上面的那些依赖工具包时都是用 apt-get 来安排的,在CentOS里采用 yum。其实都一样,只要知道依赖哪些包就行了。

本人checkout 的OpenWRT源码库路径为 : svn://svn.openwrt.org/openwrt/trunk

其它的都按上面的步骤做。

如下是我遇到的几个问题:

./scripts/feeds update -a失败

报:

$ ./scripts/feeds update -a
Updating feed 'packages' from 'https://github.com/openwrt/packages.git' ...
Cloning into './feeds/packages'...
fatal: Unable to find remote helper for 'https'
failed.

可能是git仓库路径不对,将https替换成git就可以了。

用 grep 命令搜

1
2
$ grep 'https://github.com' feeds/* -R
feeds/packages.tmp/location:https://github.com/openwrt/packages.git

那就把这个地方改一下啰。

再试一下。结果还是老样子,我想了一下,这个 feeds/packages.tmp/location 很可能是临时文。改它不会有效果的。

好像 feeds.conf.default 文件里也找到了。

$ grep 'https://github.com' feeds.conf.default -R
src-git packages https://github.com/openwrt/packages.git
src-git luci https://github.com/openwrt/luci.git
src-git routing https://github.com/openwrt-routing/packages.git
src-git telephony https://github.com/openwrt/telephony.git
src-git management https://github.com/openwrt-management/packages.git
src-git targets https://github.com/openwrt/targets.git

将里面所有https替换成git。

再试一下,OK了。

后记:其实还有更根本的解决方法,详见后期的博文《git 错误:Unable to find remote helper for ‘https’

gconvert.c libiconv

我在第一次编译OpenWRT时,出现如下错误提示:

1
gconvert.c:66:2: error: #error GNU libiconv not in use but included iconv.h is from libiconv

我在网上找解决方案,结果一致地都是说,重新 ./configure 一下:

1
2
./configure --enable-iconv=no --with-libiconv=gnu
make

可问题的关键是:OpenWRT的trunk路径下没见有个 configure 呀!

后来,经过仔细推敲,发现是在编glib时没通过。

1
2
$ find -name "gconvert.c"
./build_dir/host/pkg-config-0.28/glib/glib/gconvert.c

那我就直接进到 ./build_dir/host/pkg-config-0.28/glib/ 路径下,发现该路径下有 configure 文件。

那我说直接在该路径下编译 glib

1
2
3
$ cd build_dir/host/pkg-config-0.28/glib/
./configure --enable-iconv=no --with-libiconv=gnu
make

这样,glib 就顺利通过了编译。

再回到 OpenWRT的trunk路径下,继续 make.

libubox安装错误

报错:

从第二行看出,是用git clone工程:

1
git clone http://git.openwrt.org/project/libubox.git

整个第三行是将clone下来的源码打包tar.gz包。

于是,我访问了一下:http://git.openwrt.org/project/libubox 果然出现 404页面。看来还真没有?

我再访问了一下:http://git.openwrt.org/ 结果,发现列表里有这个工程:

进入链接 project/libubox.git:

我自己亲自 git clone 一下。

$ cd dl
$ mkdir tmp
$ cd tmp
$ git clone http://git.openwrt.org/project/libubox.git libubox
Cloning into 'libubox'...
fatal: Unable to find remote helper for 'http'

我在网上找了“fatal: Unable to find remote helper for ‘http’”的解决方法。得知将 “http:” 换成 “git:” 即可。

于是,我再次 git clone

1
$ git clone git://git.openwrt.org/project/libubox.git

结果成功clone了。

然后,手动完成编译命令过程:

rm -rf libubox-2015-03-22;

然后,回到OpenWRT的trunk路径下继续 make.

&& rm -rf netifd-2015-03-31;

找到 package/network/config/netifd/Makefile,打开

将第8行的“http:”替换成”git:”,然后再回到OpenWRT目录再make.


注:后来我还会反复遇到这个问题。火了!一条命令全部换掉!

1
2
3
$ grep -E "http:.*\.git" `find -name Makefile | xargs` | \
awk -F: '!/.svn/{print $1}' | uniq | xargs \
sed -i 's/http\(:.*\.git\)/git\1/g'

在trunk目录下,找出Makefile中有”http:xxxxx.git”的文件,并将所有的”http:xxxxx.git”替换成”git:xxxxx.git”

1
2
3
$ grep -E "https:.*\.git" `find -name Makefile | xargs` | \
awk -F: '!/.svn/{print $1}' | uniq | xargs \
sed -i 's/https\(:.*\)\.git/git\1\.git/g'

把 https 也替换成 git

opkg下载失败

Checking out files from the git repository...
Cloning into 'opkg-9c97d5ecd795709c8584e972bfdf3aee3a5b846d'...
fatal: Could not read from remote repository.

这时往上看一下,看make到哪儿了

1
make[3]: Entering directory `/home/hevake_lcj/Workspace/OpenWRT/trunk/package/system/opkg'

原来是 opkg 在 git clone 时可能是路径的问题,失败了。

我尝试打开 opkg 路径下的 Makefile,将

1
PKG_SOURCE_URL:=http://git.yoctoproject.org/git/opkg

改成:

1
PKG_SOURCE_URL:=git://git.yoctoproject.org/git/opkg

结果还是没有生效。

我手动搜opkg,找到官网: http://git.yoctoproject.org/cgit/cgit.cgi/opkg/ 打开,看到网页最下面有:

img

于是,我改 trunk/package/system/opkg/Makefile 文件,把 PKG_SOURCE_URL改成:

1
PKG_SOURCE_URL:=git://git.yoctoproject.org/opkg

继续 make,通过了!

linux-firmware clone失败

1
fatal: Unable to look up git.kernel.org (port 9418) (Temporary failure in name resolution)

我到 git.kernel.org 网站找到了 linux-firmware 的仓库 https://git.kernel.org/cgit/linux/kernel/git/balbi/linux-firmware.git/

看到最下面的 git 路径说明:

img

这与 Makefile 里指定的不统一。于是将Makefile里的git路径改过来

img

再 make

我现在都总结出经验来了。

凡是git clone失败的,如果是http头的问题,将http替换成git再试。

如果还是不行,就要检查一下git的路径是不是对的。简单的方法就是到 git 路径的根节点上去找出源码仓库,并得到其真实有效的git路径。

并将Makefile中的改过来就OK了。

fatal: reference is not a tree: f404….22c,意思好像是说git工程里没有 f404…22c 这么版本。那么我得检查一下这个版本号对不对。
