Subject: [SDL] Fix for opening documents on Mac OS X < 10.4
The current code in SDLMain.m that transforms documents opened from the
Finder into command-line arguments (introduced in revision 1.14,
2005-08-11) uses the methods -[NSString lengthOfBytesUsingEncoding:] and
-[NSString getCString:maxLength:encoding:], which are only available in
Mac OS X 10.4.
Compiling this code on 10.3 produces warnings, and running it (i.e.
starting an SDL application by opening a document) leads to weird
behavior which I didn't investigate in detail ("*** -[NSCFString
lengthOfBytesUsingEncoding:]: selector not recognized" is printed to the
console log, and the SDL window never opens).
The attached patch removes the offending calls and uses -[NSString
UTF8String] instead, which is available everywhere. Tested on 10.3.9,
and I see no reason why it shouldn't also work on 10.2 and 10.4.
Two further comments:
* The comment above the -[SDLMain application: openFile:] implementation
says "You need to have a CFBundleDocumentsType section in your
Info.plist to get this message, apparently." This is not the case in my
experience - it worked just fine with a hand-built bare-bones
application consisting only of Test.app/Contents/MacOS/test, without any
Info.plist (although you have to press the option and command keys for
such an application to accept a dragged file).
* I took the liberty of cleaning up another area of SDLMain.m: I changed
"CustomApplicationMain (argc, argv)" to "CustomApplicationMain (int
argc, char **argv)". This avoids the "type of `argv' defaults to `int'"
warnings, and I'm not sure if leaving out the types could cause problems
on platforms where an int and a char** aren't of the same size.
