openwrt patch

一：

这几天使用一款电信的4G网卡，发现了一些问题，所以决定打个pitch来解决问题，顺便把patch的生成与使用学习一下

二：安装patch的管理工具quilt

1. sudo apt-get install quilt

2.配置quilt

vim  ~/.quiltrc 创建配置文件

   1:  QUILT_DIFF_ARGS="--no-timestamps--no-index -pab --color=auto“

   2:  QUILT_REFRESH_ARGS="--no-timestamps--no-index -pab"

   3:  QUILT_PATCH_OPTS="--unified"

   4:  QUILT_DIFF_OPTS="-p"

   5:  EDITOR="vim"

三：package的patch方法

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

1.package的patch生成方法这里以usb-modeswitch-data组件为例

因此我们先进入到trunk/build_dir/target-mipsel_mips32_eglibc-2.19/usb-modeswitch-data-20120120$ 软件包目录

2.安装已有的patch（当然目前此软件包内无patch）

quilt push –a

3.创建新的patch

quilt new 001-modedata-05c6f000.path

注意：

patch文件以数字开头，-”后为patch的描述信息

patch开头的数字必须比已有patch的数字都大，使用命令quilt series查看已有patch的列表

4.修改源文件

quilt edit usb_modeswitch.d/05c6\:f000

5.查看修改内容 

quilt diff 

   1:  --- a/usb_modeswitch.d/05c6:f000

   2:  +++ b/usb_modeswitch.d/05c6:f000

   3:  @@ -1,6 +1,6 @@

.csharpcode, .csharpcode pre
{
font-size: small;

font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

6.更新修改到patch文件

quilt refresh

打印出Refreshed patch 001-modedata-05c6f000.path

并生成patches目录和文件ls patches/
001-modedata-05c6f000.path  series

7.保存patches目录以及文件到usb-modeswitch-data所在的feeds目录并重新编译软件包测试之
