Re: [Chromium-users] compiling zpix spu under windows

[Mike H. <mho...@gr...>]

An easy fix for the ulong error is to change them to "unsigned long".

However, we've never tracked down how to properly get zlib working with 
the Visual Studio compiler.  However, if you are so inclined, and are 
willing to submit patches, that would be great.

It's maybe a better idea to only use zlib under *nix and only support 
RLE/PLE compression under Windows.  This should just require ifdef's 
through the code and maybe some code shuffling to make things a little 
cleaner.  In general, I find RLE/PLE does a pretty good job without the 
CPU load of zlib.  It's been good enough to do remote rendering to my 
laptop over 802.11 at reasonable speeds.

And, Brian is correct that the code isn't as clean as it should be. 
Another Stanford researcher worked on the original code, and as usual, 
we got swamped before we could get a clean, multi-platform version of 
the code.  John Gerth (ge...@gr...) did the original 
coding, so he might be your best bet at getting help to get this working 
under Windows.  He has also done some work at speeding up the PLE path 
by removing one of the copies.

I'll be out of town for the next week, but I can try to help out a 
little when I get back.  However, I should mention that I'm at ATI this 
summer, so Chromium work from me is being done in my limited free time.
