Hi Sorry I should have mentioned that after applying the patch, I compiled fennec for x86 and am testing on a sandybridge i5 PC, running android-x86 (built from src from <a href="http://android-x86.org">android-x86.org</a>). Thanks, Maks. <div class="gmail_quote">On 7 Oct 2013 16:07, "xunxun" <<a href="mailto:xunxun1982@gmail.com">xunxun1982@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> 于 2013/10/7 星期一 13:00, Maksim Lin 写道: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Thanks xunxun! that was very helpful and let me get Siarhei's patch to compile with a recent snapshot of the code from mozilla-central repo.

I posted my code to the bug report if case some one would have any ideas on where I could have gone wrong. thanks, Maks.
