SDL + MacOS Version

SDL Development
21

As the migration to OS X will begin shortly, I think its a good idea to get
started on these problems now. What do you think?

I think a good place to start is to get all the functions fixed. Then we can
worry about directly accessing data structures and de-referencing handles.

FYI, here are all the functions in SDL we will have to find a workaround for
(to obtain Carbon compliance).

These are the link errors using CarbonLib 1.1d11:

This isn’t #defined in the Universal Headers, so you can’t just check
with #ifndef.

Is there any way to write the code so it will work on older and newer
versions of MacOS?

I don’t think the LM calls work under Carbon…Do they? :o)

No, but the whole Device Manager isn’t available under Carbon anyway, so
there isn’t any reason to access the Unit Table. :wink:

Hmm, so how do you control the CD-ROM? :slight_smile:

/dev/cdrom? :slight_smile:

BTW, I actually have SDL 1.1.3 working on OS X DP4 (sans audio and
mouse warping and joystick), used it to demo SDL Doom on OS X at
MacHack. The patches aren’t too large, but I did some heinous
things in the final hours of MacHack (as is traditional :slight_smile: ) and
am still working on conditionalizing the changes properly for both
X and 9, so that they go in smoothly.

I suppose the answer is QuickTime, which they are blam^H^H^H^H suggesting for
everything, but I don’t know if it supports red book audio – or even what the
real future is. For now, you’ll have to conditionalize it out for Carbon (or
OSX at least).

/dev/cdrom?

Very possibly, but that won’t work from a CFM Carbon app without lots of glue
(since the BSD calls all use a different format shared library). Since this is
all in flux, so I basically suggest “don’t worry about it yet”.

THanks!

Not Carbon compliant, maybe?

BTW, by my recollection there are about 15 carbon link errors in SDL at
the moment (with the latest CarbonLib).

I have carbon projects for SDL, if anyone is interested.
