[lwip-users] [lwip] Too large OBJ code size

[Imran Mansuri]

Hello to all of you

I have compiled & run the Lwip for Dos with packet
driver interface.
The probem is that i want to cross compile it for
8051.
And executable code size for the stack is 90 Kb (as i
have compiled it with Turbo C)

But 8051 permits 64 Kb code size. And i also have to
consider code space for application program.
So to port the stack I have to limit it to 30 to 50
Kb. Can any one suggest me how to proceed?
Which compiler for 8051 should I use? or I have to
think of some higher level microcontroller with more
memory.

Eventhough i removed UDP, STAT, DEBUG, TCPDUMP, PERF
modules the code size is still 88Kb.

Following is the size of various modules' OBJ code

TO Adam Dunkles

I read the LwIP documents where you showed object code
size for x86 is 22Kb but I am getting 90 KB which is
without any application protocol impl. Where is the
prob?

Awaiting for ur replies
Imran
