lwip sockets

Development Boards MicroMod

I’m using the AT91SAM7xek evaluation kit.

I’m using Eclipse, and FreeRTOS as operating system.

The lwip demo version with webserver is now running on my

microcontroller.

Now I like to configure a TCP socket connection.

Therefore I add the follwing in my makefile:

LWIP_THUMB_SRC= \

…(more and more)

lwip-1.1.0/src/api/sockets.c \

…(more and more)

When compiling → 152 warnings occur:

errno.h warning: this is the location of the previous definition (70 warnings like this)

warning: “EADDRINUSE” redefined (in arch.h) (about 30 warnings like this)

What’s going wrong? How can I solve this?

Is there a source code available for setting up and handling a TCP socket connection?

Thanks

if you use the webserver application from freertos, you laready have all the source file you need in your makefile. since webserver is tcp oriented, i don’t know why you need to put something else in your makefile.
