Subject: OS X Mouse inversion problem fix (again)
Here's yet another patch for the OS X mouse inversion
problem. This should fix the problem once and for all.
I know I've said this before, but *This time for
sure!* :)
If you recall, my last patch broke the non-OpenGL
windowed code and caused the inversion to occur there
instead. Max submitted a patch that partially reverted
the changes back which included the os version hack
which is currently the most recent CVS.
Aaron Sullivan identified and reported to the mailing
list the other day, that the last partial regression
of the code broke OS X 10.2. Looking over the results,
I'm thinking that I was slightly more successful than
I thought at unifying the code. I think I was trying
to unify the code base for OpenGL and non-OpenGL
windowed modes for all versions of the OS. It looks
like I failed at at unifying the OpenGL and non-OpenGL
code, but I did succeed at unifying the OS versions.
Thus, we no longer need the hack for the OS version
checks. The partial regression still included an OS
check which is what broke things for < 10.3.
Attached is the patch for SDL_QuartzWM.m. It basically
is a half-line change that removes one of the two
checks that decides if the mouse coordinates need to
be inverted, i.e:
if (system_version >= 0x1030 &&
(SDL_VideoSurface->flags & SDL_OPENGL) )
becomes this:
if(SDL_VideoSurface->flags & SDL_OPENGL)
With Aaron's outstanding help, we have collectively
tested:
windowed OpenGL
windowed non-OpenGL
fullscreen OpenGL
fullscreen non-OpenGL
under OS X 10.2 (Jaguar), 10.3 (Panther), and 10.4
(Tiger).
We don't have access to 10.0 or 10.1, but since the
original problem didn't materialize until 10.3, I'm
hopeful that testing 10.2 is sufficient. And now that
the code is uniform, I'm also hoping we'll be safe
moving forward to deal with future revisions of the OS
with this issue.

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>
