On Openwrt Image BUILDER/SDK

Image Builder and SDK can be downloaded from the official web and compiled on their own (make Menuconfig).
Official online download is to help you compile a good, so you can save a lot of time to compile the source code to spend,
These two things are equivalent to semi-finished products, the last thing you want to build yourself.
The development process is as follows:

After the two items of Image Builder and SDK are checked at compile time, they can be compiled.
Of course, can also be downloaded from the official website, but the website compiled by the package only support X64

The bottom two are the Image Builder and SDK.

Then unzip them separately, the name is too long, change the short point:

Here the directory and OpenWrt source package is similar, but image Builder only packaging function, so
There is no need for toolchain, just some tools to package and pre-compiled binary files.

Here the Packages directory and OpenWrt source code is not the same, here is pre-compiled IPK,
The packages directory inside the openwrt is used to store some makefile and patches for the IPK package.

To start packing, first, use make info to view the currently existing profile, which is the predefined model information:

Make info > Info.txt

There are a lot of lines out here, and here are some of the lines you're interested in:

These lists should be extracted from the. Targetinfo below the root directory (the file Manager will hide it)

Where default packages is the IPK that will be compiled into the binaries. Then each of the following models corresponds to the
Packages is the package that I want to add

You can see that there are TLWR740, then start compiling:

Make image profile= "TLWR740"

You can see that a bin folder was generated.

Ready to start the brush machine, the system before the brush machine (Mercury mw150r):

After the brush machine:

The original is not installed Luci.
Telnet success, further explained that has been brushed, but the lack of Luci.

The Luci has been prepared for us here:

So compile these things in:

Make image profile="TLWR740" packages="luci-app-firewall luci-base Luci-lib-ip Luci-lib-nixio luci-mod-admin-full luci-proto-ppp luci-theme-bootstrap Luci"

Now the compiled bin has risen from 2.87MB to 3.3MB:

After brushing the Luci appeared:

Next, use the SDK to make a HelloWorld:

Reference: http://jphome.github.io/blog/2014/03/29/openwrt_sdk.html

After creating the appropriate files and directories, use make v=99 to generate:
Finally get a IPK file

To compile it in:

Make image profile="TLWR740" packages="luci-app-firewall luci-base Luci-lib-ip Luci-lib-nixio luci-mod-admin-full luci-proto-ppp luci-theme-bootstrap Luci HelloWorld"

After brushing the firmware, I found it was already inside.

Then execute the Helloword (there may be a problem with Telnet, H is not shown)
