libvpx-1.0.0 breaks firefox and thunderbird

jagdpanther · Post by **jagdpanther** » Wed Feb 29, 2012 4:04 pm

I just emerged libvpx-1.0.0 and firef0x-10.0.1 and thunderbird-10.0.1 wouldn't start. revdep-rebuild showed firefox and thunderbird needed to be re-emerged. Emerging firefox and thunderbird both faild near the start of the compile. The error stated that libvpx >= 0.9.7-r1 was needed. Well I had 1.0.0 installed. I suspect an issue in an ebuild file. The quick fix: emerge --oneshot =media-libs/libvpx-0.9.7-r1. Then the 'old' firefox and thunderbird worked again.

Same problem here. I solved it for the moment by disabling the USE-Flag webm.

I'm seeing it too. I just put

Code: Select all

=media-libs/libvpx-1.0.0

into my package.mask for the time being.

Did you file a bug?

Happened here too.
Jagdpanther's solution worked for me.

alright, just to make sure I understand this. each time I emerged firefox and thunderbird (cause I wanted to do a world update) I had this message. Now reading (damn those ABC books when I was little payed off) the error message in the read * area told me the libvpx wasn't installed. The odd thing is I emerged libvpx and it was version 1.0

I did the world update again and got the same problem. After that, I began to explore this forum (once again

) and found this thread. I followed what jagdpanther and it worked. My firefox (version 9 wtf ?

works).

sooo..

1. So this oneshot option in others words doesnt add libvpx0.97 in the world file. This means that later if I want to update firefox when it should work ?

2. what is that webm USE flag ? Just to be sure does it mean that if I disable that flag, I wont be able to view html5 video ?

The error message printed in the failure case is misleading. As noted in the bug report, the configure script uses a strange and wrong way of testing for the library. It then reports that the library is missing if the test fails. Due to legitimate changes in libvpx-1.0, the test fails when it should succeed.

bigbangnet: yes. According to equery use firefox, USE=webm appears to be necessary for HTML5 WebM video. If Firefox supports other video formats, those are likely not affected.

same here.

Which fix is better the mask or the use flag?

Just for the record, my firefox, thunderbird and seamonkey failed without the webm USE flag enabled, but
masking =media-libs/libvpx-1.0.0 worked for me.

Thanks for the helpful solution.

If you have firefox 10.0.1 refer to this [bug=401985]bug[/bug], save the patch entitled "Patch to require (correctly) libpvx-1.0.0 during the Firefox 10.0 build process" to /etc/portage/patches/www-client/firefox you will then be able to (re)build firefox
