I strongly recommend you to submit your GNUstep packages to their (Ubuntu's)
main repository - the packages there are way too old to use.
And my distro is actually aimed as a non-OS X environment that can compile
Objective-C just as easy as OS X. Take the following code as an example:
#import <Foundation/Foundation.h>
int main(void)
{
@autoreleasepool
{
NSLog("%@", @[@"foo", @"bar", @"bat", @"qux", @1, @2, @3, @4]);
}
}
The @autoreleasepool think will not compile with either GCC (even GCC 4.7) or
link properly clang with GCC runtime or the old GNUstep runtime came with
Ubuntu package (it works using Apple's clang under OS X). The @[...] array
works under Apple clang, but neither Ubuntu GCC nor stock Ubuntu clang will
compile it. The @1 NSNumber literals won't even compile with Apple compiler as
of now but a new svn build of clang will work.
And now about building. A simple "clang foo.m -o foo" will compile this thing
on OS X but on Ubuntu (I still use 32-bit) I need to do "clang foo.m -o foo
`gnustep-config --objc-flags` `gnustep-config --base-libs` -fobjc-abi-version=3
-fobjc-arc" (so complicated to the extent that a makefile would preferred in
case of any typing errors, and oh yes I defaults to ARC)
My distro is to simplify this entire procedure to the extent that I can build
ObjC apps written using Xcode on OS X can build in the OS X fashion. And I will
call it myLinux and a variant called myLinux-llvm which is compiled entirely
(including the kernel) using clang is planned.
Oh and just FYI, this first myLinux is called myLinux 10.8.2 Melodie Luna -
taking its version number from the most recent OS X version.
