Using SDL with Microsoft Visual C++ 5,6&nbsp;and 7

<p>
You can either use the precompiled libraries from <A HREF="http://www.libsdl.org/download.php">
the SDL Download web site </A>, or you can build SDL yourself.
</p>
<H3>
Building SDL
</H3>
<P>
Unzip the <CODE>VisualC.zip</CODE> file into the directory that contains this
file (<CODE>VisualC.html</CODE>).
</P>
<P>
Be certain that you unzip the zip file for your compiler into <strong>this</strong>
directory and not any other directory. If you are using WinZip, be careful to
make sure that it extracts to <strong>this</strong> folder, because it's
convenient feature of unzipping to a folder with the name of the file currently
being unzipped will get you in trouble if you use it right now. And that's all
I have to say about that.
</P>
<P>
Now that it's unzipped, go into the VisualC
directory that is created, and double-click on the VC++ file "<CODE>SDL.dsw</CODE>"<STRONG><FONT color="#009900">
("<CODE>SDL.sln</CODE>").</FONT></STRONG> This should open up the IDE.
</P>
<P>
You may be prompted at this point to upgrade the workspace, should you be using
a more recent version of Visual C++. If so, allow the workspace to be upgraded.
</P>
<P>
Build the <CODE>.dll</CODE> and <CODE>.lib</CODE> files.
</P>
<P>
This is done by right clicking on each project in turn (Projects are listed in
the Workspace panel in the FileView tab), and selecting "Build".
</P>
<P>
If you get an error about SDL_config.h being missing, you should
copy include/SDL_config.h.default to include/SDL_config.h and try again.
</P>
<P>
You may get a few warnings, but you should not get any errors. You do have to
have at least the DirectX 5 SDK installed, however. The latest
version of DirectX can be downloaded or purchased on a cheap CD (my
recommendation) from <A HREF="http://www.microsoft.com">Microsoft </A>.
</P>
<P>
Later, we will refer to the following .lib and .dll files that have just been
generated:
</P>
<ul>
<li> SDL.dll</li>
<li> SDL.lib</li>
<li> SDLmain.lib</li>
</ul>
<P>
Search for these using the Windows Find (Windows-F) utility, if you don't
already know where they should be. For those of you with a clue, look inside
the Debug or Release directories of the subdirectories of the Project folder.
(It might be easier to just use Windows Find if this sounds confusing. And
don't worry about needing a clue; we all need visits from the clue fairy
frequently.)
</P>
<H3>
Creating a Project with SDL
</H3>
<P>
Create a project as a Win32 Application.
</P>
<P>
Create a C++ file for your project.
</P>
<P>
Set the C runtime to "Multi-threaded DLL" in the menu: <CODE>Project|Settings|C/C++
tab|Code Generation|Runtime Library </CODE>.
</P>
<P>
Add the SDL <CODE>include</CODE> directory to your list of includes in the
menu: <CODE>Project|Settings|C/C++ tab|Preprocessor|Additional include directories </CODE>
.
<br>
<STRONG><FONT color="#009900">VC7 Specific: Instead of doing this I find it easier to
add the include and library directories to the list that VC7 keeps. Do this by
selecting Tools|Options|Projects|VC++ Directories and under the "Show
Directories For:" dropbox select "Include Files", and click the "New Directory
Icon" and add the [SDLROOT]\include directory (ex. If you installed to
c:\SDL-1.2.5\ add c:\SDL-1.2.5\include).&nbsp;Proceed to&nbsp;change the
dropbox selection to "Library Files" and add [SDLROOT]\lib.</FONT></STRONG>
</P>
<P>
The "include directory" I am referring to is the <CODE>include</CODE> folder
within the main SDL directory (the one that this HTML file located within).
</P>
<P>
Now we're going to use the files that we had created earlier in the Build SDL
step.
</P>
<P>
Copy the following files into your Project directory:
</P>
<ul>
<li> SDL.dll</li>
</ul>
<P>
Add the following files to your project (It is not necessary to copy them to
your project directory):
</P>
<ul>
<li> SDL.lib </li>
<li> SDLmain.lib</li>
</ul>
<P>
(To add them to your project, right click on your project, and select "Add
files to project")
</P>
<P><STRONG><FONT color="#009900">Instead of adding the files to your project it is more
desireable to add them to the linker options: Project|Properties|Linker|Command
Line and type the names of the libraries to link with in the "Additional
Options:" box.&nbsp; Note: This must be done&nbsp;for&nbsp;each&nbsp;build
configuration (eg. Release,Debug).</FONT></STRONG></P>
<H3>
SDL 101, First Day of Class
</H3>
<P>
Now create the basic body of your project. The body of your program should take
the following form: <CODE>
<PRE>
#include "SDL.h"
int main( int argc, char* argv[] )
{
// Body of the program goes here.
return 0;
}
</PRE>
</CODE>
<P></P>
<H3>
That's it!
</H3>
<P>
I hope that this document has helped you get through the most difficult part of
using the SDL: installing it. Suggestions for improvements to this document
should be sent to the writers of this document.
