I am trying to use lwip on ARM cortex M4. My development software is Atollic Truestudio on Win10. So far I have gotten lwip 1.4.1 to work using raw api and a simple multitasking OS.Now I am trying to change over to lwip 2.0.3, and am having trouble with initialization. My initialization code is as follows: #include "lwipopts.h" #include "lwip/tcpip.h" #include "lwip/tcp.h" struct netif wiznetif; // network interface struct for wiznet ... static void initialize_lwip(void) { struct ip_addr ipaddr, netmask, gateway;
Since 1.4.0, "struct ip_addr" is an "internal" type, and applications should use "ip_addr_t", which is a typedef and keeps us more free to change the types. We do have struct ip_addr (Dirk suggested to add the appropriate include), but I just saw it's only defined for dual-stack mode.
You should instead convert your software from "legacy" (i.e. pre 1.4.0) coding style to just use ip_addr_t.
