Re: [webkit-dev] Building Chromium port of WebKit on Windows
OK, following setup instructions for the buildbot, I was able to compile the port under Windows. Thanks again, Dimirti!

[webkit-dev] Building Chromium port of WebKit on Windows
Hello Chromium port maintainers, In order to figure out why my patch was failing to compile on the Chromium WebKit bot, I went a long way of compiling the port on my machine. And it was a tough experience! As for the instructions on on how to do the build, I could only refer to this page: http://trac.webkit.org/wiki/Chromium and bot logs. And they were not enough for me, so I would like to ask you some questions, as that might be helpful for other people trying to build this port. - it looks like VS2008 is required to build the Chromium port (as for Chromium itself), while building plain WebKit requires VS2005 (according to http://www.webkit.org/building/tools.html). Does that mean it's impossible to use a single checkout of WebKit for building both? - from bot logs, it looks like 'update-webkit' and 'build-webkit' scripts are launched under Strawberry Perl, not from cygwin, as all paths are of MS-DOS style. I tried this way, and it didn't worked at all. E.g. for some reason it couldn't find Python, although I have it in path; - then I followed instructions from http://trac.webkit.org/wiki/Chromium and ran those scripts under cygwin. It almost worked, except for the issues below: - ffmpeg.rules, libjpeg.rules and webcore_bindings_sources.rules were expected to be found in project directories, while actually they were generated into Source\WebKit\chromium; - several Python scripts (from Source\WebCore\WebCore.gyp\scripts) were receiving MS-DOS paths for output, which were becoming incorrect after applying os.path.abspath to them (under cygwin, the function was just prefixing paths with '/cygdrive/c/...'); - also it looks like several output paths were of MS-DOS style, because I've found generated files under paths like 'C?/src/WebKit/...', and was needed to copy them to their designated locations; - and vice versa, in generated .rc files there were cygwin-style paths to resources, resulting in a failure for Visual Studio's resources compiler to find them; - and, as I was building the port with VS2005, I've encountered some compilation and linking problems mostly fixable by installing hotfixes. I have tried to do the build on two machines, so I hope this isn't a problem of a particular system configuration. But the bot works fine, and this makes me think that perhaps I was doing something wrong or missing some important steps. ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev

Re: [webkit-dev] Building Chromium port of WebKit on Windows
The way I make this work is to set up a full Chromium checkout with a trunk (rather than DEPS-controlled) WebKit checkout. (There are some instructions for this in the Chromium developer pages.) Then I can use VS2008 to build and test whatever I want. And I use Cygwin. I don't know much about trying to build the Chromium port with only a WebKit (not Chrome) checkout, especially under Cygwin. I don't know how many people try to make that work. PK ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev

Re: [webkit-dev] Building Chromium port of WebKit on Windows
I'm not sure we are on the same page. I'm talking about Chromium port of WebKit, where Chromium checkout is _inside_ WebKit's Source/WebKit/chromium, as opposed to when you have full WebKit checkout inside Chromium's third_party. Not sure the former configuration makes much sense for Chromium developers, but I suppose it is needed for Chromium port of WebKit to be recognized on par with other ports. I also usually have full checkout of WebKit in Chromium's third_party and it works fine for me.

Re: [webkit-dev] Building Chromium port of WebKit on Windows
To make things clear: my only intention for trying to build this port was due to my patch failed to compile in it. I'm not advocating towards using it for regular development. Perhaps, I would get the same compile issue when building Chromium on Windows, but, as I usually avoid using Windows, and haven't had a ready-to-use configuration at that moment, I decided to try to build the port, to make sure that this isn't a bot issue. Dimitri, I'm currently following building the port using your instructions for setting up a build bot, and it almost works, thank you very much! I'll update docs later, after I'll finish with it.
