Note: This video is old; some things have changed since it was made:

• In Visual Studio 2008 Express (and up), if you're using FLTK 1.1.10 or older, before starting the build, change the following option:
  Tools->Options->Projects and Solutions->General->Build And Run->Max parallel builds: 1

  Set that field to '1', to prevent parallel builds.

  The reason for this: FLTK 1.1.10 (and older) project files do not support the new parallel build features in VS 2008 Express and up. Only the newer version, fltk 1.3.x and up, supports parallel builds.

• The fltk.org website changed; To download the fltk source code, you now have to go to the FLTK LIBRARY | DOWNLOAD section of the fltk.org website.
• In version fltk 1.3.x, the "fltk.dsw" was moved to "ide/VisualC6/fltk.dsw".
  In older releases (fltk 1.1.10 and back), it was in "visualc/fltk.dsw".
• When setting up your own app, there are likely different windows libraries that need to be included under the Linker > Command Line > Additional options since this video was made. Try building one of the FLTK test programs most like your app (eg. the "hello" example), and look at the build log to see what libs it uses to build, then update your linker accordingly. Or, look at the linker settings for the test program, and set your app up similarly.
