this very simple code can not build with betterC

void test(byte[] x){
	
}

extern(C) int main(string[] args){
      byte[] data = [0, 1];
	test(data);
	return 0;
}

Well yes, dynamic arrays require the GC and hence TypeInfo. Slices don't, but that isn't a slice as it isn't from some random malloc'd memory.

this line:
>>> byte[] data = [0, 1];
is an dynamic array allocated with GC.
But if you declare as a static array like
>>>byte[2] data = [0, 1];
than its not GC allocated.

Or use C malloc.

We really should provide better tools to create arrays using C malloc (for those who want them). Like a betterC toolkit.

Indeed, i´m creating my own "toolkit" for betterC stuff like
alloc!Type(length); (much safer than malloc!) and other utilities :)

Need to declare main() like those C people do:

  extern (C) int main(int argc, char** argv){

Thanks for all you help, the betteC is really useful and handy.

I am try to made mobile app (right now IOS), seems Dan Olson 's great IOS work is stopped since 2 years ago.

Hope the D community get better and better with more betterC Cross platform support.

That's great to hear!
