I'm told that yasm now fully supports SAFESEH on Win32, so we should, in theory, be able to build libvpx on Win32 using the newest version of yasm.
Created attachment 462263 [details] [diff] [review] Use yasm to assemble libvpx on win32 I tested this with yasm r2348  on Windows 7. The yasm devs indicated to me that they'd be willing to spin a 1.0.2 release sometime soon, although personally I'm fine including their trunk build in Mozilla Build.  http://www.tortall.net/projects/yasm/snapshots/r2348/yasm-r2348.exe
This patch should probably check the yasm version to make sure it's 1.1.0 or greater. (v1.1.0 is the final name of the 1.0.2 release mentioned above.) My configure-fu is not so great, however.
Generally you'd just run yasm --version and use sed to capture the version number, then do some awful shell logic to test that the version is what you want.
All right; canceling this review until I add in the yasm version check.
Created attachment 465731 [details] [diff] [review] Patch v2 Now with a yasm version check. Of course, we can't check this in at least until yasm 1.1 is on the Windows build machines and is included in some version of mozilla-build.
The documentation at https://developer.mozilla.org/en/YASM will need to be updated. Just noting that here so that it's not forgotten.
Per comment 6.
Comment on attachment 465731 [details] [diff] [review] Patch v2 Nice.
Comment on attachment 465731 [details] [diff] [review] Patch v2 Requesting approval 2.0. Thanks for the review!
We can't land this without bug 583924 being fixed anyway, right?
Make sure that when you rebase this on tip that you don't regress bug 587363.
(In reply to comment #10) > We can't land this without bug 583924 being fixed anyway, right? Yes. Do you think I should wait to request approval until that one gets fixed?
(In reply to comment #11) > Make sure that when you rebase this on tip that you don't regress bug 587363. Nice catch. Thanks.
Ted, I'm not too familiar with how we handle updates which will break people if they're using the old MozillaBuild. Can we check this in (pending approval) now that the win32 build machines have the new yasm, or do we need to somehow notify Windows users that the need to update their build system?
If it won't break the build machines you can land it. If you're going to require everyone to update to MozillaBuild 1.5.1, please post to dev.planning and blog about it before landing, so most people know. Also, make the error message on Windows very explicit about updating to MozillaBuild 1.5.1.
Actually, this blocks bug 593753 which blocks bug 584253 which blocks release, so I don't need approval for this patch. I posted to dev.planning and will post to my blog (and syndicate to pmo) tomorrow.
I don't believe blocking works transitively.
(In reply to comment #17) > I don't believe blocking works transitively. Apparently not. I'll request approval again.
Alternately, you could request blocking since this blocks a blocker of a blocker. :)
Pushed to try: Try push: http://hg.mozilla.org/try/rev/ffdf2f66d8b8 If all goes well, I'll land tomorrow morning.
cpearce actually pushed this patch to try yesterday, and it looked good. I'll land soon! http://hg.mozilla.org/try/rev/1178065b0dbb
http://hg.mozilla.org/mozilla-central/rev/3056a0e0d970 broke comm-central Windows!
(In reply to comment #23) > http://hg.mozilla.org/mozilla-central/rev/3056a0e0d970 > broke comm-central Windows! You probably need to install YASM 1.1 (or the new MozillaBuild 1.5.1?) on the c-c build machines?

(In reply to comment #26) > Bug 594468. > I just wished this bug had waited for the updates to be done :-/ I'm sorry. I tried to make sure we'd been loud enough about this change, but I clearly didn't do a good enough job.
Would someone like to update these pages to mention that YASM is required, and details about how to get and install it? Should be pretty trivial, but would be best coming from someone that's done it: https://developer.mozilla.org/En/Developer_Guide/Build_Instructions/Windows_Prerequisites#Software_Requirements https://developer.mozilla.org/en/YASM https://developer.mozilla.org/En/Simple_Firefox_build
It comes with MozillaBuild 1.5.1, so updating the docs should be easy.
Someone (Ted, I presume) updated the main YASM page. I took care of the other two.
that means that is libjpeg turbo coming ?
