Python error while compiling Firefox 32.0.3 under Slackware64 14.1

moisespedro · 09-27-2014, 04:04 PM

Hi, I am trying to upgrade Firefox using this instead of something simpler like ruario's SlackBuild because I want to try to see how it improves HTML5 support.

I am using all SlackBuilds unmodified from here and all of them went fine, except Firefox.

I've started it with:

Code:

LANG=C MOZLOCALIZE=pt-BR sh mozilla-firefox.SlackBuild 2>error.log

error.log:

Code:

chmod: cannot operate on dangling symlink './media/webrtc/trunk/webrtc/tools/e2e_quality/audio/perf'
client.mk:214: /tmp/mozilla-release/obj/.mozconfig.mk: No such file or directory

Perhaps you need python-virtualenv?

I don't have it installed and the build works fine.

These two errors don't cause any problems with the build:

Code:

chmod: cannot operate on dangling symlink './media/webrtc/trunk/webrtc/tools/e2e_quality/audio/perf'
client.mk:214: /tmp/mozilla-release/obj/.mozconfig.mk: No such file or directory

Can you upload the full log somewhere?

Your error seems to be OpenSSL-related:

https://trac.torproject.org/projects/tor/ticket/12462

moisespedro · 09-27-2014, 07:52 PM

I am using mancha's OpenSSL build. I will mark this as solved (I rather keep things the way they are now than build Firefox).

mancha · 09-27-2014, 08:08 PM

Hi moisespedro.

If that's the case then your OpenSSL doesn't have SSL 2.0 support. Please take a look at my SSL 2.0 thread and pay particular
attention to the caveat utilitor halfway down. Your issue might be that you didn't re-build Python and possibly M2Crypto.

Try again after re-building those two packages against your OpenSSL.

--mancha

I was aware of that thread, I just didn't take time to rebuild all it was posted there. I only rebuilt neon, so far. I thought python was going to be much harder because I've misread you at this: "If you want to use it with LibreSSL you'll have to patch Python so it doesn't use RAND_egd." I probably missed the "LibreSSL" part. I am going to rebuild them and see if everything works correctly now.

And before creating this thread I thought it could have been related to OpenSSL but I wasn't sure.

Anyways, thanks again.

moisespedro · 09-27-2014, 08:53 PM

Ok, I am confused now. I am still not sure if I got everything correclty: am I supposed to rebuilt Python and M2Crypto with unmodified SlackBuilds? Because I just tried that and I got the exact same error messages. The logs are equal.

What happens when you try the following:

Code:

$ python
Python 2.7.5
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import ssl

moisespedro · 09-27-2014, 09:00 PM

Code:

 pedro@slack [~] $ python

ImportError: No module named _ssl

That's the problem then. You're using my first OpenSSL slackbuild. Check the note at the end of this post.

Your slackbuild should be disabling SSL 2.0 with no-ssl2 and probably has -DOPENSSL_NO_SSL2.

I had downloaded your new version but I think I messed up something while extracting the files/moving the directories around.

Just for curiosity I've ran diff against both directories (the one in my SlackBuilds folder, which I used to compile OpenSSL and the openssl-20140916.tar.bz2 extracted folder under /home/pedro/Downloads)

I am recompiling it right now.

Well, the compilation went fine but nothing really change regarding HTML5 support.

html5test.org dropped from 475 to 471 points

youtube still doesn't have H264 support (everything else is marked as green).

That's because Firefox doesn't support MSE and H.264. MSE works with some other codecs with these settings in about:config:

Code:

media.mediasource.enabled
media.mediasource.ignore_codecs

Quote:

I get 477. But it doesn't really matter, because if the gstreamer base package is present on the system almost all tests regarding HTML5 video and audio automatically go green. Firefox can't distinguish which codecs are present and which are not. Unless you really want to play a file and it doesn't work.

There's another test here: http://www.quirksmode.org/html5/tests/video.html

With the pre-built version of Firefox, the H.264 video at the top doesn't run. With my packages, it does.
