First, during configure, this appears<br><br>configure: WARNING: libc.h: present but cannot be compiled<br>configure: WARNING: libc.h:&nbsp;&nbsp;&nbsp;&nbsp; check for missing prerequisite headers?<br>configure: WARNING: libc.h: see the Autoconf documentation
<br>configure: WARNING: libc.h:&nbsp;&nbsp;&nbsp;&nbsp; section &quot;Present But Cannot Be Compiled&quot;<br>configure: WARNING: libc.h: proceeding with the preprocessor's result<br>configure: WARNING: libc.h: in the future, the compiler will take precedence

config.h to remove <br><br>#define socklen_t int<br><br>because configure wrongly concludes it is absent from the system headers.&nbsp; It is also the cause of the warning during configure.<br><br>Then, the build ends during the link step with
