Description Marcin Juszkiewicz 2016-02-23 12:54:48 UTC
Description of problem:

qt5-qtwebengine is using libvpx as build dependency. But on AArch64 build fails due to lack of vpx_codec_enc_init_multi_ver() in ;(

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. do build of qt5-qtwebengine (arm-koji is enough for scratch builds)

Actual results:

/builddir/build/BUILD/qtwebengine-opensource-src-5.6.0-beta/aarch64-redhat-linux-gnu/src/core/Release/obj/src/3rdparty/chromium/third_party/webrtc/modules/video_coding/codecs/vp8/libwebrtc_vp8.a(/builddir/build/BUILD/qtwebengine-opensource-src-5.6.0-beta/aarch64-redhat-linux-gnu/src/core/Release/obj/src/3rdparty/chromium/third_party/webrtc/modules/video_coding/codecs/vp8/webrtc_vp8.vp8_impl.o) webrtc::VP8EncoderImpl::InitAndSetControlSettings(): error: undefined reference to 'vpx_codec_enc_init_multi_ver'

Expected results:

qt5-qtwebengine package builds

Comment 1 Tom "spot" Callaway 2016-02-23 20:49:18 UTC
I don't have aarch64 hardware, and I can't even download the libvpx build you're referencing:

Best guess is that because aarch64 isn't natively supported, the generic-gnu target that it is using is not fully featured enough.

If you can give me shell access to an aarch64 system (preferably with sudo so I can install BuildRequires), I might be able to fix this.

Comment 2 Marcin Juszkiewicz 2016-02-24 06:14:24 UTC
Tom: Beaker has some aarch64 machines available.

Comment 3 Marcin Juszkiewicz 2016-03-08 13:34:58 UTC
If I unset generic_target for 'generic-gnu' builds then vpx_codec_enc_init_multi_ver() is available on aarch64/ppc64 (not checked s390).

And then:

Comment 4 Tom "spot" Callaway 2016-03-09 01:47:08 UTC
Can you give me the full build logs from the aarch64 build with generic-gnu unset. I'm not sure that libvpx knows how to build for aarch64, but if qt5-qtwebengine linked against it... i'm wondering if it detected as armv7 and just worked with the %{optflags}. Just need to know how to conditionalize it in the spec.

Created attachment 1134395 [details]
results of libvpx build (logs, rpms, srpm)

This is whole results directory including build logs, resulting rpms and source rpm used.

Aha, okay, I see what is going on now. I'll get that fixed in a moment.
