Fixed bug #943
Ozkan Sezer 2010-02-06 12:31:06 PST
Hi:
Here are some small fixes for compiling SDL against mingw-w64.
(see http://mingw-w64.sourceforge.net/ . Despite the name, it
supports both win32 and win64.)
src/audio/windx5/directx.h and src/video/windx5/directx.h (both
SDL-1.2 and SDL-1.3.) I get compilation errors about some union
not having a member named u1 and alike, because of other system
headers being included before this one and them already defining
DUMMYUNIONNAME and stuff. This header probably assumes that those
stuff are defined in windef.h, but mingw-w64 headers define them
in _mingw.h. Easily fixed by moving NONAMELESSUNION definition to
the top of the file.
src/thread/win32/SDL_systhread.c (both SDL-1.2 and SDL-1.3.) :
The __GNUC__ case for pfnSDL_CurrentBeginThread is 32-bit centric
because _beginthreadex returns uintptr_t, not unsigned long which
is 32 bits in win64. Changing the return type to uintptr_t fixes
it.
video/SDL_blit.h (and configure.in) (SDL-1.3-only) : MinGW-w64
uses msvcrt version of _aligned_malloc and _aligned_free and
they are defined in intrin.h (similar to VC). Adding proper
ifdefs fixes it. (Notes about macros to check: __MINGW32__ is
defined for both mingw.org and for mingw-w64 for both win32 and
win64, __MINGW64__ is only defined for _WIN64, so __MINGW64__
can't be used to detect mingw-w64: including _mingw.h and then
checking for __MINGW64_VERSION_MAJOR does the trick.)
SDL_win32video.h (SDL-1.3-only) : Tweaked the VINWER definition
and location in order to avoid multiple redefinition warnings.
Hope these are useful. Thanks.

Do not unzip it into any other directory because the makefiles ( *.mak ) and project files ( *.bpr ) use relative paths to refer to the SDL sources. This should create a directory named "Borland" inside of the top level SDL source directory. </p> <h3> <b><a name="bcbwin"></a> Using Borland C++ Builder 5, 6 for Windows </b> </h3> <p> Inside of the "Borland" directory there is a "bcb6" directory that contains a number of Builder project files. Double-click on the "libSDL.bpg" file icon. Once Builder has started click on the "<u>P</u>rojects" menu on the menu-bar and go down to "B<u>u</u>ild All Projects" option. <br> This will proceed to build SDL ( with Borland's calling convention ), SDLmain, and all the <a href="#tests">test programs</a>. Currently, all the <a href="#tests">test programs</a> are dynamically linked to Sam Lantinga's SDL.dll.</p> <p><b>NOTE :</b> Borland's "lib" format and Microsoft's "lib" format are incompatible. <br> If you wish to dynamically link to the SDL library supplied by Sam Lantinga in each release, I have created the correct *.libs for SDL 1.2.4 and they exist in the "/lib" directory.<br> If you would like to create the *.lib files yourself, you will need to make use of Borland's "implib.exe" utility.<br> </p> <p><tt>IMPLIB</tt> works like this: </p> <pre> IMPLIB (destination lib name) (source dll)<br></pre> <p> For example,</p> <pre> IMPLIB SDL.lib SDL.dll<br></pre> <p>This assumes that SDL.dll was compiled with Visual C++ or similar.<br> </p> <p>To learn more about the difference between Borland's and Microsoft's *.lib format please read the article <a href="http://www.bcbdev.com/articles/vcdll.htm">here</a>.<br> </p> <p> <b><br> NOTE :</b> The C++ Builder for Windows project format, is not compatible with the Kylix 3 project format, hence the reason why they are in separate directories.</p> <h3> <b><a name="bccc"></a> Using the free Borland C++ command-line compiler </b> </h3> <p> The free Borland compiler can be downloaded at no charge from <a href="http://www.borland.com/bcppbuilder/freecompiler/"> the Borland website </a>. Make sure that it is installed and properly configured. </p> <p> Open an MS-DOS Prompt. Change to the "Borland\freebcc" directory under the SDL source directory. Type "make -f SDL.mak" to build SDL and "make -f SDLmain.mak". There are also makefiles for all of the <a href="#tests">test programs</a>, if you wish to build them. All .exes and DLLs are created in the "test" SDL directory. Ify ou would like to create the DLL and all the test applications, I have thrown together a basic batchfile called "makeall.bat" which should create everything in the right order. </p> <h3> <b> Output files </b> </h3> No matter which compiler you used, three important files should have been produced: <ul> <li> SDL.dll ( Borland format ) </li> <li> SDL.lib ( Borland format ) </li> <li> SDLmain.lib ( Borland format ) </li> </ul> Both of the *.lib files will need to be added to all the projects that use SDL and SDL.dll must be placed some where the Windows dynamic linker can find it (either in your project directory or on the system path, C:\WINDOWS\SYSTEM). <h3> <b><a name="k3"></a> Using Borland C++ Builder for Linux ( AKA Kylix 3 ) </b> </h3> <p> Inside of the "Borland" directory there is a "k3" directory that contains a number of Builder project files. Double-click on the "libSDL.bpg" file icon. Once Builder has started click on the "<u>P</u>rojects" menu on the menu-bar and go down to "B<u>u</u>ild All Projects" option. This will proceed to build all the <a href="#tests">test programs</a>. <br> Linux users do not need *.lib files as the Shared Object is linked right into the project ( very neat actually, Windows should do this sort of thing as it is a lot easier for the developer ). <br> <b>NOTE :</b> The C++ Builder for Windows project format, is not compatible with the Kylix 3 project format, hence the reason why they are in separate directories.</p> <p> On Mandrake 8.1 the shared objects for SDL are located in the /usr/lib directory as libSDL_*.so and the Mesa OpenGL shared objects are located in /usr/X11R6/lib as libGL*.so<br> <br> So if your setup is different you may need to change the project file so that they re-link to the ones on your system.<br> <br> On Mandrake 8.1 the headers files are located at /usr/include/SDL/. So if you you have not installed the development RPMs ( usually named libSDL-devel* ) for SDL ( not included ) you may have to change the include directory within some of the projects.<br> </p> <h3> Known Problems</h3> The only known problem is that I ( Dominique Louis ), was unable to create the projects that rebuilt the SDL shared objects under Linux, due to time constraints and my lack of intimate knowledge of Linux. <h3><a name="tests"><b> Test programs </b> </a></h3> Some of the test programs require included media files ( *.wav; *.bmp etc ). All the test programs are now created in the "test" directory, where the media files are ( usually ) so they should be ready to go. <br> <br> <br> <br> </body> </html>
