[chromium-dev] Re: cygwin dependence missing?
Okay, I think I've figured this out and it's a relatively undocumented aspect of our win builds (from what I can tell). The third_party/cygwin install we have has a modified version of cygwin1.dll , which has been patched to tell cygwin the root is third_party/cygwin rather than /. In order for this to work correctly, you need to run third_party/cygwin/setup_mount.bat to stuff the right entries into the registry. We should probably change run_layout_tests to automatically run this script prior to running the regression (running it every time should be harmless). -- Dirk On Thu, Jul 2, 2009 at 7:27 PM, Dirk Prankedpra...@google.com wrote: Debugging this a bit more ... it seems to be some sort of XP vs. Vista thing.

There isn't a cygwin under depot_tools, unless you have something I don't. setup_mount.bat creates a bunch of registry entries that tells cygwin where to find the root of its source tree. Read the source for that file and the README.google in that directory; they're pretty clear about what's going on (enough so that me repeating it here wouldn't add anything). Unless you either had those files added at some point, or somehow managed to install cygwin into the same path, I'm not sure why it would be working for you on one machine and not the other. --~--~-~--~~~---~--~~ Chromium Developers mailing list: chromium-dev@googlegroups.com View archives, change email options, or unsubscribe: http://groups.google.com/group/chromium-dev -~--~~~~--~~--~--~---
[chromium-dev] Re: cygwin dependence missing?
That's really weird, as I posted, between the two same layout-tests, one succeeded on XP of my notebook, one failed on XP of my PC. I totally agree with you, I think that must be something wrong about ENVIROMENT, such as PATH. FYI: my PATH=D:\Program Files\Perl\bin;D:\Program Files\Perl\site\bin;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;D:\Program Files\Rational\common;D:\Program Files\Rational\ClearCase\bin;C:\Python24;C:\Python24\Scripts;D:\depot_tools; --~--~-~--~~~---~--~~ Chromium Developers mailing list: chromium-dev@googlegroups.com View archives, change email options, or unsubscribe: http://groups.google.com/group/chromium-dev -~--~~~~--~~--~--~---

Well,new headway is I found it's really a weird bug. I copies the same source from my pc to my notebook(both are Windows XP), and run layouttest. The one on pc is still with the cygwin errors I've posted, but the notebook's succeeded without any cygwin error.

Just guessing, access controls.
