I'm using ESP8266_NONOS_SDK_V1.5.2_16_01_29 downloaded from viewtopic.php?f=46&t=850.
During compilation I'm getting this error :

I don't know whether its proper fix or not but I fixed it by replacing 'lib/libwap.a' and 'lib/libwpa2.a' with 'lib/libwpa.a' of SDK v1.4.0.
Is it a proper fix ?
Thanks & regards,
