  13                 <p>
  14                         You can either use the precompiled libraries from <A HREF="http://www.libsdl.org/download.php">
  15                                 the SDL Download web site </A>, or you can build SDL yourself.
  16                 </p>

  18                         Building SDL
  19                 </H3>
  20                 <P>
  21                         Unzip the <CODE>VisualC.zip</CODE> file into the directory that contains this
  22                         file (<CODE>VisualC.html</CODE>).
  23                 </P>
  24                 <P>
  25                         Be certain that you unzip the zip file for your compiler into <strong>this</strong>
  26                         directory and not any other directory. If you are using WinZip, be careful to
  27                         make sure that it extracts to <strong>this</strong> folder, because it's
  28                         convenient feature of unzipping to a folder with the name of the file currently
  29                         being unzipped will get you in trouble if you use it right now. And that's all
  30                         I have to say about that.
  31                 </P>
  32                 <P>
  33                         Now that it's unzipped, go into the VisualC
  34                         directory that is created, and double-click on the VC++ file "<CODE>SDL.dsw</CODE>"<STRONG><FONT color="#009900">
  35                                         ("<CODE>SDL.sln</CODE>").</FONT></STRONG> This should open up the IDE.
  36                 </P>
  37                 <P>
  38                         You may be prompted at this point to upgrade the workspace, should you be using
  39                         a more recent version of Visual C++. If so, allow the workspace to be upgraded.
  40                 </P>
  41                 <P>
  42                         Build the <CODE>.dll</CODE> and <CODE>.lib</CODE> files.
  43                 </P>
  44                 <P>
  45                         This is done by right clicking on each project in turn (Projects are listed in
  46                         the Workspace panel in the FileView tab), and selecting "Build".
  47                 </P>
  48                 <P>
  49                         If you get an error about SDL_config.h being missing, you should
  50                         copy include/SDL_config.h.default to include/SDL_config.h and try again.
  51                 </P>
  52                 <P>
  53                         You may get a few warnings, but you should not get any errors. You do have to
  54                         have at least the DirectX 5 SDK installed, however. The latest
  55                         version of DirectX can be downloaded or purchased on a cheap CD (my
  56                         recommendation) from <A HREF="http://www.microsoft.com">Microsoft </A>.

  58                 <P>
  59                         Later, we will refer to the following .lib and .dll files that have just been
  60                         generated:

  67                 <P>
  68                         Search for these using the Windows Find (Windows-F) utility, if you don't
  69                         already know where they should be. For those of you with a clue, look inside
  70                         the Debug or Release directories of the subdirectories of the Project folder.
  71                         (It might be easier to just use Windows Find if this sounds confusing. And
  72                         don't worry about needing a clue; we all need visits from the clue fairy
  73                         frequently.)
