Hi,

I'm trying to build lwip with the "traditional" BSD style socket interface.
I suspect that I have neglected to set something, the question is what ?

I have set the following in lwipopts.h
#define LWIP_NETCONN 1
#define LWIP_SOCKET 1
#define LWIP_COMPAT_SOCKETS 1
#define LWIP_POSIX_SOCKETS_IO_NAMES 1

When I do the build I get the following errors:

In file included from ../../../include/lwip/memp.h:45:0,
from ../../../include/lwip/stats.h:38,
from ip_frag.c:47:
../../../include/lwip/memp_std.h:55:95: error: macro "LWIP_MEMPOOL" requires 5 arguments, but only 4 given
LWIP_MEMPOOL(NETBUF, MEMP_NUM_NETBUF, sizeof(struct netbuf), "NETBUF")

and

In file included from ../../../include/lwip/stats.h:38:0,
from ip_frag.c:47:
../../../include/lwip/memp.h:79:31: error: 'MEMP_MAX' undeclared here (not in a function)
extern const u32_t memp_sizes[MEMP_MAX];

Thanks in advance.

regards,
Andrew

Hi, I Confirm this when you set LWIP_SOCKETS = 1 !!!

Any solution for this So far?

The lib has not been tested with the socket interface. Always used it with esp_conn.

Perhaps you might want to use this one: https://github.com/d-a-v/esp82xx-nonos-linklayer

Contains the NAPT and is included in esp8266-Arduino.

I try to compile with different options in lwipopts.h (to investigate UDP broadcast issues of repeater) , which crashes too:
eg. NO_SYS=0
LWIP_NETIF_API=1
