Hi John,<div><br></div><div>If you look in the CMakeCache.txt of your build tree there should be an entry FFMPEG_LIBRARIES. What does it contain?<br><br><div class="gmail_quote">On Wed, Aug 31, 2011 at 4:07 PM, John Haiducek <span dir="ltr"><<a href="mailto:jhaiduce@gmail.com">jhaiduce@gmail.com</a>></span> wrote:<br>

make[2]: *** [bin/QVTKCxxTests] Error 1<br>
make[1]: *** [GUISupport/Qt/Testing/Cxx/CMakeFiles/QVTKCxxTests.dir/all] Error 2<br>
make: *** [all] Error 2<br>
<br>
The error goes away when I add -lswscale to my CXXFLAGS, but surely<br>
there's a better way to fix it?<br>
