Perhaps try the following:<br>-Ensure if lv2core folder contains lv2.h:  ls /usr/include/lv2/<a href="http://lv2plug.in/ns/lv2core/">lv2plug.in/ns/lv2core/</a><br>-run ./waf build, and post the error message here, it will probably say [2/9] blah blah file stuff.<br>
-Open that file that its complaining about, and check to see what #include stuff its doing regarding lv2.<br><br>With some more info on what file its failing on I can check what&#39;s going wrong on my machine here.<br>Cheers, -Harry<br>
