Hello,
a vm_alloc error is a C library error, something gcc
has no control over (it's Apple's C library). But I
think G5s top out at 8 gigabytes RAM or so, and the
amount you're asking to allocate is a lot more than
that!
Cheers,
Dara

It's worse than that; right now, an individual process is limited to 32
bit pointers, so it can only allocate 2 GB.

Really? I could have sworn I'd read something to the
contrary elsewhere. So -mpowerpc64 only affects long
long on g5, not void *, or anything else? Thanks,
Dara

Frankly, I don't know. But to me it seems you're trying to allocate an
array which needs 2 TB of memory. Do you really have that much memory?
In that case, these G5 boxes must be a lot better than I thought.

Hi,
I'm trying to use g++ in darwin os-x running on a g5 system with
a powerPC 970 chip.
I've written the following piece of code:
unsigned long long alloc = 1LL<<41;
ptr = new char[alloc];
I get a vm_alloc error.
Is the g++ limited to a 32-bit address space on darwin os-x on g5?
