[lwip-users] problems compiling lwIP

[franz keuner]

Hi,
thanks for your help. Now I`m using the lwIP version 1.0.0 as a base and the
only file I had to add was the ip.h file (head version - because of the bug
in the Tasking EDE).
With this minor modification my project can be compiled.

But I`m still having the problem that the linking process isn`t executed.

The message generated by the Tasking EDE is still:
total errors: 0, warnings: 2
Linking and locating to project.out
E 243: module inet.obj (INET_C): symbol '_htons': multiply defined
E 243: module inet.obj (INET_C): symbol '_ntohs': multiply defined
E 243: module inet.obj (INET_C): symbol '_htonl': multiply defined
E 243: module inet.obj (INET_C): symbol '_ntohl': multiply defined
total errors: 4, warnings: 0
wmk: *** action exited with value 1.

The only place in the entire source code of the project where these
definitions are made is in the inet.h file (listing
below,lwip\src\include\ipv4\lwip\inet.h)

I tried a few things by editing this file and the definitions but none of
them met with success.

Best regards,
Franz
