GNUstep should work as good with gcc as it does with clang.
Hi Fred,
Just to clarify, does GCC now support features like ARC, blocks and
grand central dispatch?
Thank you,
Patryk
ARC and Blocks: no
GCD is just an API, so as long as you don't use functions accepting
blocks, you should be fine.
Yes and no. There is a kernel GCD and there is a Foundation GCD, and
kernel GCD is not necessarily stable when used with Foundation, at
least on Apple.
I should rephase that. On Apple, Foundation is not necessarily stable
when used with kernel GCD. If you are using Foundation at all, then if
you wish to use GCD, you must use the Foundation GCD mechanisms
(NSOperation, NSOperationQueue, etc.), rather than the kernel GCD
mechanisms (dispatch_get_main_queue, etc.). Naturally, this has no
direct bearing on whether the code will work on GNUStep, but there is a
portability danger, and the problem involves race conditions, so it may
work for months and then suddenly start to fail.
