Thanks Jerry,

I was building with vs2008.

Downloaded the source built with no errors but warnings. 

This is good to see after all the challenges of the past couple of weeks trying 
to get the cairo build of webkit to work correctly.

Noticed that the projects are still set to use the MANIFEST option. Will play 
tomorrow and see how I get on.

Might try moving everything to vs2010 and see where that gets me. A small task I 
am sure :-)

It I succeed I will make doing the build for everything in one place much easier 
and I should not get the issues I have been experiencing with the side by side 


As for the vs2008 projects, I have a copy of the webkit pool that builds (with 
help of Chris Waldron) and I am reluctant to do an svn update as it might break 
may build. I setup a vm and installed that with vs2008/cygwin and the latest svn 
pool. Had some minor issues with the environment but still got problems building 
using vs2008. 

I have got my "working" build out side of the cygwin directory by using the 
environment variables:


This made life much easier and less reliance on the cygwin structure

Looking at the waterfall status, it says the Windows Release build is green for 
good build. I dont believe this! I copied my "working build" pool to the vm and 
this did a successful build where the one from the trunk did not. 

This is a very frustrating working on this. Our end goal is to get webkit 
embedded into our app. thus removing the reliance on the installed version of IE 
and to have a good html 5 rendering platform to do some good html5 stuff with. 
After reading how good webkit and how popular it is for embedded projects, 
thought it was worth the effect. I am beginning to wonder!!

This does sounds like I am knocking all the work and effect that has gone into 
the cairo webkit build, I am not and it most be an up hill struggle to keep this 
 stuff in check and building on multple platforms. My whinge is about the 
complexity of a Windows build using bits of linux environment (cygwin), getting 
the build environment set up in the first place.

Something that says a good build (the waterfall status) and it does not. I will 
admit that they is no easy or quick solution to solve some of this issues, but 
this does not help me or other people who are trying to build a version of 
webkit for windows.


Thanks for all the hard work you and brent put into this project.
