I wrote a module based on LUCI and now I am finding a way to compile these files into binary.
As found on COMPEX's access points, their modified LUCI files are all binary files. So this is quite good for hiding some important modules, how can I do that? Any help will be appreciated and thanks

No, I don't think the module files are compiled into binary. I wrote some applications, but the process is much similar. You put your files in the directory maybe "modules", and make some modification in makefile, perhaps some more changes some where else. After all the work, the files will be copied to different directories when you compile the files. But they are just your original files. These files and directories will composed of the file structure of AP. There are some binary file.
Well, the ap system will compile the .lua file under the controller into binary and store them in a file named luci-indexcache and luci-modulecache for modules I tell from the directory name. The binary files is for efficiency. They are compiled in run time. So This is what I know about it. I hope it can help. If something wrong, please let me know, discussion is always appreciated.

Thanks Wandy. As I found on my COMPEX's box, all of LUCI controller and CBI model files are in binary format (still come with extension of *.lua), and I cannot read the content as text file as usual.
As in http://lua-users.org/wiki/LuaTools , I can found a lot of tools for compile LUA file such as LUADEC51, but do not know how to use them in OpenWrt. I tried to decompile some files I took from my box but failed.
This is content from controller file named system.lua:

Fire up "make menuconfig" and have a look at "LuCI ---> Libraries ---> Build Target". In there, you can select that everything will be precompiled.
The discussion might have continued from here.
