I have been away from this code for too long...:)
When compiling memp.c with the NO_SYS set to 1
memp.c fails to compile due to tcpip.h not providing the definition of
struxt tcpip_msg.
Adding lines to condition the use of the struct lets the compile proceed,
but I am not sure if this is the right fix. See below the two code
snippets. the #if !NO_SYS and the corresponding #endif are the added
lines.
static const u16_t memp_sizes[MEMP_MAX] = {
sizeof(struct pbuf),
sizeof(struct raw_pcb),
sizeof(struct udp_pcb),
sizeof(struct tcp_pcb),
sizeof(struct tcp_pcb_listen),
sizeof(struct tcp_seg),
sizeof(struct netbuf),
sizeof(struct netconn),
sizeof(struct api_msg),
#if !NO_SYS /* don't build if not configured for use in lwipopts.h */
sizeof(struct tcpip_msg),
#endif
sizeof(struct sys_timeout)
};
static u8_t memp_memory[(MEMP_NUM_PBUF *
MEM_ALIGN_SIZE(sizeof(struct pbuf) +
sizeof(struct memp)) +
MEMP_NUM_RAW_PCB *
