compilation error for server example #2

I opened the AsyncUDPServer example....didn't change anything....tried to compile:

In file included from C:\Users\java_\Documents\Arduino\libraries\ESPAsyncUDP-master\examples\AsyncUDPServer\AsyncUDPServer.ino:2:0:

C:\Users\java_\Documents\Arduino\libraries\ESPAsyncUDP-master\src/ESPAsyncUDP.h:81:58: error: 'u16_t' has not been declared

 void _recv(udp_pcb *upcb, pbuf *pb, ip_addr_t *addr, u16_t port);

I'm guessing that u16_t should have been uint16_t I changed ESPAsyncUDP.h line 81 and AsyncUDP.cpp line 171 from u16_t to uint16_t

recompiled and got the following errors: In file included from C:\Users\java_\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\2.1.0\libraries\ESP8266WiFi\src/lwip/inet.h:37:0,

I was looking for an async udp library (to fetch time from a ntp server), and BAM! you added one a day ago. (I'm hoping it works as well as your ESPAsyncTCP library which is brilliant)

Which Arduino Core are you on? I'm on todays git version and everything compiles with no error...

cdadgar commented 8 years ago

I'm on 1.6.8
l'll try 1.6.9 and if that doesn't work, get latest git. Thanks for the reply.

esp8266 arduino 2.3.0 (stable from 6/23/16) works better but still has 2 compilation issues. me-no-dev modified UdpContext.h 5 days ago which fixes the problem. So, with esp8266 arduino latest fro github, it complies cleanly.

bleeding edge...truly.
