Hello,
I maintain a cross-platform project that uses SDL.
One of the users who runs OSX has told me that he has problems with linking to
SDL due to missing -framework option.
I think that the problem is because of this:
'sdl-config --libs' outputs '-L/opt/local/lib -lSDLmain -lSDL
-Wl,-framework,Cocoa'
All the options are passed to the linker except the last one. I think that the
good output should be just:
'-L/opt/local/lib -lSDLmain -lSDL -framework Cocoa'
since those options (--libs) are passed to the linker, so the '-Wl' option is
redundant and possibly harmful in this very case
I use autotools with libtool to do the build...
Regards,
Matej

SDL_VIDEO_DRIVER_X11 is not defined in SDL_config_macosx.h
There's a number of SDL_VIDEO_DRIVER_xxx defined in SDL_config_macosx.h, but
not that one, even though it is actually present.

configure.in will enable dynamic loading by default for modules, but some of
the checks only check /lib, /usr/lib, /usr/local/lib, etc...
It needs to also account for systems using /lib64, /usr/lib64, and
/usr/local/lib64.
For example, openSUSE x86_64 distro uses these style paths. Otherwise, i586
gets dynamically loaded, but x86_64 doesn't.
SDL_SemWaitTimeout in src/thread/generic/SDL_syssem.c line 179 (SVN trunk):
--sem->count;
should be
if (retval == 0) {
--sem->count;
}
Without this, sem->count will underflow on timeout effectively breaking the
semaphore. It appears that the implementation has been wrong since the initial
revision.
Hi,
so here we go: GL_LINE_SMOOTH bad for business! ;)
I checked the code within SDL_renderer_gl.c / GL_CreateRenderer(..)
and have found the reason for blurred lines when using OpenGL.
I have attached 2 images here.
I don't know whether this has to be changed and I don't know if there
is an option to turn it off/on...just wanted to say that with GL_LINE_SMOOTH
enabled there is a difference when rendering with opengl compared to directx.
The linux code appears to be complete and *should* be the base of all Unix and GCC based versions. The macosx and win32 versions
are currently just copies of the dummy code. I will begin working on the windows version as soon as this check in is done. I
need someone to work on the Mac OS X version.
I'm afraid that this check in will break QNX (Sorry!)
I noticed in trunk/SDL/src/video/win32/SDL_win32events.c, in this code here...
... if the device handle isn't found in mice[], which it won't be if
the mouse was plugged in after SDL_Init, then you end up with an
uninitialized value in index, which is then passed to various
SDL_SendMouse* functions.
