Minimal perfect hash function

I have many integers in range [0; 2^63-1]. There is only 10^8 integers, however. There is no duplicates. Full list is known at compile-time but it is just unique random numbers. These numbers never changes.
To store one integer explicitly, 8 bytes required, and there is associated 1-byte values, so explicit storing requires about 860 MB.
So I want to find minimal perfect hash function to map each of 10^8 integers from [0;2^63-1] to [0;10^8-1]. I should find this function only once, data never changes, and function can be complicated. But it should be minimal, perfect, and calculating should be fast. How I can do this better? Maybe it is possible to find and use some subsequences if they happens?
Thanks.
