Are you sure you make && make install the wayland library first, and then the demo? Also double check all environmental variables from the build tutorial. You may also add<div>PKG_CONFIG_ALLOW_SYSTEM_CFLAGS=1</div> <div>because on my system pkg-config just skipped some libraries.</div><div><br></div><div>Regards,</div><div>Iskren<br><br><div class="gmail_quote">On Sun, Mar 13, 2011 at 8:20 PM, Matt Hoosier <span dir="ltr"><<a href="mailto:matt.hoosier@gmail.com">matt.hoosier@gmail.com</a>></span> wrote:<br> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Verified on both counts.

In master of that repo, the struct is declared (but not defined). The 'terminal' branch does have its definition, but the 'terminal' branch looks out-of-date.
