Hi Chuck,

I've only recently started using LV2, and decided to document exactly what I done to get it all running.
Here's the link to the whole article: http://harryhaaren.blogspot.com/2011/05/lv2-new-host-lib-lilv-newbies-guid-to.html

Here's the except you want:

If you get the following errors:
Checking for header lv2/lv2plug.in/ns/lv2core/lv2.h : no
Checking for header lv2/lv2plug.in/ns/ext/event/event.h : no
Checking for header lv2/lv2plug.in/ns/ext/event/event-helpers.h : no
Checking for header lv2/lv2plug.in/ns/ext/uri-map/uri-map.h : no

Then this is what you do:
1. Direct your browser to http://lv2plug.in/spec/
2. Grab lv2core,lv2-event, and lv2-uri-map.
3. Untar lv2core, ./waf configure, ./waf, ./waf install it (the first one should be fixed now)
4. Bop open a terminal, cd /usr/include/lv2/lv2plug.in/ns/
5. sudo mkdir ext
6. Copy the event folder into ext, and copy the uri-map folder in too.
7. *CHECK THE DIRECTORY STRUCTURE!!!* the output of ./waf configure tells you *exactly* where its looking for the files, *PUT THEM THERE*. Can't stress this enough. Use your brain & figure out what's not where its meant to be

./waf configure should print out yes yes yes yes yes yes to all dependencies now, so
./waf build,

HTH! -Harry
