Hi

 

>1. Is it possible to use lwip libraries for this?

Yes

>2. Where should i look for target dependencies in lwip libraries? Any documentation on this?

There is no real hardware dependencies, it seems that lot of different targets use it

3. Any standard procedure to be followed to build lwIP libraries? i couldn't see any standard makefiles or configure scripts.

>It's true. Except for linux or MSVC, there is no build tools. For you case (I will suppose you don't use sequential apis, like netconn or socket), files you need to put in your makefile should be:

4. Is it possible to build lwIP libraries for UDP support alone?

Yes. You have to create a lwipopts.h file which contains options to enable/disable (see opt.h to know existing options).

 

You can file some informations on :

Objet : [lwip-users] Building lwIP libraries - general info

Hi all,

I am a newbie to lwip. I have an embedded target board running which does not have any OS support.
I need to implement UDP stack on this board.

1. Is it possible to use lwip libraries for this?
2. Where should i look for target dependencies in lwip libraries? Any documentation on this?
3. Any standard procedure to be followed to build lwIP libraries? i couldn't see any standard makefiles or configure scripts.
4. Is it possible to build lwIP libraries for UDP support alone?

Any help will be very much useful.

Regards,
Rohit
