I am new to lwip and have many
questions. I have read most of the documentation, but the puzzle is still a
bit unclear.
For starters, after downloading
the distribution from Savanna, what other files are
necessary?
I found a port of lwip for UCOS-II
which I currently have running well on a Motorola hcs12
microcontroller.
The port contained lib.c,
sys_arch.c cc.h, perf.h and sys_arch.h.
I found cpu.h, debug.h, and
lwipopts.h by searching the web (after getting compiler errors that they were
missing)
I am unsure what lwip files I need
to actually include into my project. Do I just use the files in the API
directory? I read the docs and noticed a description of how to send and
receive using different api’s, but some of these functions are in tcp.c – do
make calls to the functions in this file?
Its quite unclear at this
point.
Additionally, when I try to
compile sockets.c, I get all kinds of errors like ; missing and typdef name
expected, type specifier mismatch, missing ) etc.. in ip_addr.h in this
area…
PACK_STRUCT_BEGIN
struct ip_addr
{
PACK_STRUCT_FIELD(u32_t
addr);
}
PACK_STRUCT_STRUCT;
PACK_STRUCT_END
#ifdef
PACK_STRUCT_USE_INCLUDES
# include
"arch/epstruct.h"
#endif
/* For compatibility with BSD code
*/
struct in_addr
{
u32_t
s_addr;
};
I don’t see anything obviously
wrong, but I am new to this and don’t really understand the pieces
fully.
Thanks for the
help,
