[lwip-users] Building lwip and ip.h et al not being found

[Chris Frost]

I was quite excited to see the existance of lwip a few weeks back, and
am beginning to port it to a small os now. In building lwip in
the enviroment, I see that lwip/api.h includes "lwip/ip.h". But, this file does
not exist. Specically, the compiler error:

i386-jos-elf-gcc -pipe -nostdinc    -fno-builtin -I. -MD -Wall -Wno-format 
-ggdb -DJOS_USER -I./inc/net/ -I./inc/ -c -o obj/user/net/api/api_lib.o 
lib/net/api/api_lib.c
In file included from lib/net/api/api_lib.c:37:
./inc/net/lwip/api.h:39:21: lwip/ip.h: No such file or directory
In file included from ./inc/net/lwip/api.h:41,
                 from lib/net/api/api_lib.c:37:

In file included from ./inc/net/lwip/api.h:41,
                 from lib/net/api/api_lib.c:37:


At first I thought that perhaps I needed to link either the ipv4 or the
ipv6 files to lwip/, but this breaks the build later on with redeclarations
for ipv6 .c files. (I'd be fine with having just ipv4, if this matters?)

Could anyone help me clarify what I seem to be missing here?
thanks!
