&gt; I&#39;m new to yocto and bitbake and I&#39;m building a voip application for a<br>
&gt; custom imx6 board. I want to use  pjsip libraries to build my application, I<br>
&gt; have compiled pjsip in my yocto build and generated pjsip libraries ( all<br>
&gt; pjsip libraries r static). I&#39;m having issues building a recipe for my<br>
&gt; application that calls the pjsip functions. Below is how my recipe looks<br>

<br>
Try splitting this into two commands. First compile rttapp.c to<br>
rttapp.o and then link the final application as a second step. When<br>
linking the application, ensure that rttapp.o is listed on the command<br>
line before the libraries which provide the symbols it requires.<br>
<br>
&gt; }<br>
&gt;<br>
&gt;<br>
&gt; When i do bitbake rttapp, the error i see is as below<br>
&gt;<br>
&gt;<br>
&gt; Log data follows:<br>
