As a follow up of previous post, the issue is confirmed to be located at the prebuilt phase of libsofia_sip_ua_static lib<br>ie at<br><br><i>if not exist &quot;$(ProjectDir)..\..\sofia-sip\win32\gawk.exe&quot; cscript /nologo &quot;$(ProjectDir)..\util.vbs&quot; Get <a href="http://files.freeswitch.org/downloads/win32/gawk.exe" target="_blank">http://files.freeswitch.org/downloads/win32/gawk.exe</a> &quot;$(ProjectDir)..\..\sofia-sip\win32\&quot;<br>

cd /D &quot;$(ProjectDir)..\..\sofia-sip\win32\&quot;<br>set AWK=&quot;$(ProjectDir)..\..\sofia-sip\win32\gawk.exe&quot;<br>&quot;autogen.cmd&quot;</i><br><br>What seems to happen is that after gawk.exe is loaded, the prebuilt is trying to go on while concurrently the anti-virus/protection is checking<br>

the gawk.exe -&gt; this creates a mess and concludes with a failure and then missing headers and so on.<br><br><b>What I&#39;ve done is simply to preload gawk.exe in the target directory, declared it as safe to the AV/Firewall and only then launch the VS built.</b><br>
<br>So as a suggestion, loading gawk ahead (ie at thbeginning of the build) could be a way<br>
<br>btw. The previous discussed recommendations (changes) related to SDK 7.1 are valid <br>
