I must be doing something wrong. I want to build and execute a 64 bit
C++ program on my iMac and it does not appear to be doing the right
thing.
I am using Xcode 3.1.2 on Mac OS X 10.5.7 on iMac with Intel Core 2
Duo processor. Based on what I know, I have a 64-bit enabled platform.
So, I go to the Xcode project build info page for my C++ project to
make sure the architectures designate 64 bit. I have one architecture
that mentions 64 bit which is called "32/64-bit Universal". I am
assuming from what I have read that this is supposed to give me LP64
architecture -- long is 64 bit, pointer is 64 bit. But, if I merely
print out the sizeof a pointer or long I get 4 bytes for each.
In the Architectures selection box there are no other options
available. Now, there is the ability to add others via the Others...
option but am I supposed to do this since there is nothing in any
documentation that I can find that suggests that this is needed.
So, what am I missing?
phil
