Re: Heads up: Runtime selection flag in clang

[Ivan Vučica]

Awesome! I suppose this means we could now more easily target this iOS5 binary compatibility layer?

I presume one "just" needs to compile the fork of Apple's libobjc as provided by Magenta project, in something like Scratchbox targeting ARMEL, and then try getting gnustep-make to use that runtime?

Hi Everyone,

Clang now has an option for explicitly specifying the Objective-C runtime to use: -fobjc-runtime=.  This currently supports:

macosx (The 'modern' OS X runtime with the non-fragile ABI)
macosx-fragile (The 'legacy' OS X runtime with the fragile ABI)
ios (The iOS runtime, which is more or less the same as the OS X one)
gnustep (libobjc2 from GNUstep svn)
gcc (The runtime shipped with GCC)

These largely supersede the old combination of runtime target flags (-fobjc-nonfragile-abi, -fno-objc-legacy-dispatch and so on).  These are still supported, but they are mapped to the new runtimes now.

Please test this!
