Hello

 

I think you're mixing lwIP 0.7.1 and lwIP 1.2.0 files -which is a very bad idea since the lwIP architecture changed a lot between those two releases.

 

Please make sure you use either lwIP 0.7.1 or lwIP 1.2.0.

 

Have a nice day

Subject: [lwip-users] LWIP problem

Hi


I tried to use lwip in my project.I am using lwip version 0.7.1.
I have now liblwip.so file in lwip-0.7.1/ports/unix/proj/lib/ folder.
Lot of warnings but it did it. But the problem is that if i link
liblwip.so file and the includes in my project and i try to compile my project it says lot of warning in lwip :(
I've checked from nabble.com that if i do this it should work:

Add $(LWIPDIR)/core/raw.c to COREFILES
Add $(LWIPDIR)/core/ipv4/ip_frag.c to CORE4FILES
Add $(LWIPARCH)/*.c and $(LWIPARCH)/netif/*.c to ARCHFILES
Add the macros for enabling/disabling debugging per module to lwipopts.h

But it doesn't work :(

I did those and i added defines in lwipopts.h file:

#define DELIF_DEBUG 0
#define SIO_FIFO_DEBUG 0
#define TAPIF_DEBUG 0
#define TCPDUMP_DEBUG 0
#define TUNIF_DEBUG 0
#define UNIXIF_DEBUG 0

if i try to compile lwip 0.7.1 it create this liblwip.so file but if i try to link it in my project it says:

../linux_lwip_1.2.0/ports/unix/proj/lib/liblwip.so: undefined reference to `sys_arch_sem_wait'
../linux_lwip_1.2.0/ports/unix/proj/lib/liblwip.so: undefined reference to `sys_sem_new'

../linux_lwip_1.2.0/ports/unix/proj/lib/liblwip.so: undefined reference to `sys_sem_free'
../linux_lwip_1.2.0/ports/unix/proj/lib/liblwip.so: undefined reference to `tapif_init'
../linux_lwip_1.2.0/ports/unix/proj/lib/liblwip.so: undefined reference to `sys_mbox_new'
../linux_lwip_1.2.0/ports/unix/proj/lib/liblwip.so: undefined reference to `sys_sem_signal'

Anyone have idea what i should do to get this lwip to work ??
I don't think that there's something wrong in my project or that makefile..
I think there's something wrong in lwip or lwip's makefile etc.. :)

Jukka
