<div dir="ltr"> am building ffmpeg and stuck in an unusual spot. Inside libavutil we
 have float_dsp.h and float_dsp.c files. Inside these file there is a 
declaration of a methond which is:

<pre style class=""><code><span class="">void</span><span class=""> </span><span class="">(*</span><span class="">butterflies_float</span><span class="">)(</span><span class="">float</span><span class=""> </span><span class="">*</span><span class="">av_restrict v1</span><span class="">,</span><span class=""> </span><span class="">float</span><span class=""> </span><span class="">*</span><span class="">av_restrict v2</span><span class="">,</span><span class=""> </span><span class="">int</span><span class=""> len</span><span class="">);</span><span class="">

<p>when building and compiling this file i get this error and have no 
idea what to do. I think problem is somewhere else but again have no 
idea at all. Error is</p>
