Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().

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.

Building SDL
</H3>
<P>
Go into the VisualC directory and double-click on the Visual Studio solution for your version of Visual Studio, e.g. <CODE>SDL_VS2008.sln</CODE> This should open up the IDE.
</P>
<P>
There are different solution files for the various

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>
You may get a few warnings, but you should not get any errors. You do have to
have at least the DirectX 9 SDK installed, however. The latest
version of DirectX can be downloaded 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> SDL2.dll</li>
<li> SDL2.lib</li>
<li> SDL2main.lib</li>
</ul>
<P>
Search for these using the Windows Find (Windows-F) utility inside the VisualC directory.

Creating a Project with SDL

<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>
.

<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 (e.g. If you installed to
c:\SDL\ add c:\SDL\include).&nbsp;Proceed to&nbsp;change the
dropbox selection to "Library Files" and add [SDLROOT]\lib.</FONT></STRONG>

<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).

Now we're going to use the files that we had created earlier in the Build SDL
step.

Copy the following files into your Project directory:

<ul>
<li> SDL2.dll</li>

Add the following files to your project (It is not necessary to copy them to
your project directory):

<P>
Now create the basic body of your project. The body of your program should take
the following form:
<PRE><CODE>
#include "SDL.h"
int main( int argc, char* argv[] )
{
// Body of the program goes here.
return 0;
}
</CODE></PRE>

That's it!

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.
