Greetings Chuckists -- This looks like a lot of fun, but I have one axe to grind. I see that the question of 64-bit chuck came up on the mailing list 2 years ago and after reviewing the code I can see why nothing has happened since. It's a little unfriendly to be so coy about this. You're very careful to discourage Mac and Windows users from attempting to recompile from sources. But someone who's trying to compile on a 64-bit operating system gets no warnings, no cautions, no under construction signs, nothing from the download and build web pages to indicate any problems at all. If you look through the information files of the downloaded sources for indications of 64-bit problems, you find: VERSIONS: - corrected more issues on some 64-bit systems VERSIONS: - corrected issues on some 64-bit systems Until you get around to fixing it, could you at least mention somewhere on the web pages or in the information files that your code truncates 64 bit pointers to 32 bits before dereferencing them so we can stop figuring it out the hard way? Please? Thanks, -- rec --
