OpenWrt SDK to build your own IPK installation package using the SDK

The Openwrt SDK is a relocatable, pre-compiled Openwrt toolchain for cross-compiling individual user-space packages for a specific platform without having to compile the entire system from scratch. Reasons for using the SDK: to compile the updated version of the specified package file for a specific release version of the custom software to ensure binary and feature compatibility

Use a custom patch or different features to recompile a package that already exists

#-----Official documents are as followsThis is the OpenWrt SDK. It contains a stripped-down version of the BuildRoot. You can use it to test/develop packages without have to compile your own toolchain or any of the libraries included with OpenWrt. To use it, just put your buildroot-compatible package directory of the SubDir ' package/' and run ' make ' from this director Y.

Here's how:

Use the SDK to build your own IPK installation package,  
Download   http://pan.baidu.com/share/link?shareid=123840&uk=1577556057

1. Unzip the
Tar jxvf openwrt-sdk-ar71xx-for-linux-i486-gcc-4.6-linaro_uclibc-0.9.33.2.tar.bz2

2. Go to Directory
CD openwrt-sdk-ar71xx-for-linux-i486-gcc-4.6-linaro_uclibc-0.9.33.2

3. Copy your code directory to the package directory in this directory
    Note Makefile must comply with OPENWRT rules, refer to
   http://blog.chinaunix.net/uid-27194309-id-3432651.html

4. Compile, after successful in the Bin/ar71xx/packages directory can see the relevant IPK file, the use of WINSCP copy out
#编译所有组件
make v=99  

# Compile a component separately
make Package/hid/compile

5. Install to the router experiment, this you all know.

#注: Do not change the directory of the SDK, otherwise the following error will appear
