Hi Chris and Alex,

Many thanks for these replies.

Is there an alternative build method I could use in order to create the blocks runtime on Linux?  The docs seemed to recommend cmake ('cmake -G "Unix Makefiles" ../llvm'), but I'd be more than glad to try another way.  I think blocks are required for GNUstep, since it's an Objective-C runtime.

Thanks,

David
