Compile error with ESP8266 SDK in KAA 0.10.0
<p>I have built the ESP8266 SDK according to <a href="https://kaaproject.github.io/kaa/docs/v0.10.0/Programming-guide/Using-Kaa-endpoint-SDKs/C/SDK-ESP8266/" rel="nofollow noreferrer">this document</a>.</p>

<p>But the compile report shows the error below. Attachemnt is the ld file. Would you please help me to resolve it? Thanks a lot!</p>
