Hi,

I'm currently trying to write a 'decoder' for HDCD. As usual for me, I've
been doing this first using the 'Norcroft'/Acorn 'C' compiler. The idea
being that once I'd got that running I'd do another version with gcc for
Linux. Normally, this works fine, but I've run into a snag...

Part of the bit-bashing requires some bit patterns to be compared against a
'window' that is 64 bits long and the results brought together. In the
example I've seen for MS this uses a uint64_t which I assume is an unsigned
int 64 bits long. The snag is that - so far as I know - the 'Acorn'
compiler doesn't include 64bit long ints. (Or am I wrong?)

Is there an easy fix for this?

if not I'll give up and switch to gcc for Linux, then maybe learn to use
gcc instead on RO for this project. But if possible I'd prefer a fix that
lets me define and use 64 bit unsigned ints with the 'Acorn' compiler.

I can give more details of the specific task if people wish.

Slainte,

Jim
