I'm trying to make a dll with some stored values, looking to store
several million doubles in a static array like this:

double delta[x_size][y_size][z_size];
void delta_init() {
delta[0][0][0] = 8.65;
delta[0][0][1] = 1.35;
delta[0][0][2] = 2.11;
delta[0][0][3] = 3.29;
delta[0][0][4] = 5.147;

etc ...

I broke up the arrays into several header files. I'm trying to compile
the code under Visual C++ Pro 2005, and the code just does not compile
- it runs over 10 hours and just hands there. I was able to compile
smaller arrays though.

How can I make the code compile? What is a better way to do this?

Personally, I'd dump the data into a binary file and bind this file as a
resource to my app. At run-time, retrieve the data with FindResource /
LoadResource / LockResource.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
