Bug 694960 – dev-qt/qtwebengine-5.12.5 fails to build with new media-sound/pulseaudio-13.0 : conflicting declaration of C function ‘pa_context_state_t pa_context_get_state(pa_context*)’

except from failed qt-webengine build log

After masking media-sound/pulseaudio-13.0 and reverting to media-sound/pulseaudio-12.2-r2, dev-qt/qtwebengine-5.12.5 builds as expected.

I was clued into this possibility through both the error messages reported in the build log and also bug #694896 www-client/chromium-77.0.3865.75 fails to build with new media-sound/pulseaudio-13.0

Because I successfully built qt-webengine after reversion to pulseaudio-12.2-r2, I do not have the relevant failed build log available. I therefore attached as text the except from the terminal window I originally ran the emerge @world process in. As I read the failure messages, there is an interaction with chromium involved here.

[Comment 1 Guy 2019-09-19 12:29:11 UTC]

As additional info, inspection of the original "emerge --pretend @world output" shows the following order for package processing

[ebuild     U  ] media-sound/pulseaudio-13.0
[ebuild     U  ] www-client/google-chrome-77.0.3865.75
[ebuild     U  ] dev-qt/qtwebengine-5.12.5

i.e. pulseaudio and google-chrome completed before qtwebengine failed.

Of note: I only reverted pulseaudio in order to successfully complete qtwebengine. Of course, I could _only_ revert pulseaudio as emaint removed the prior versions of google-chrome.

[Comment 2 wolfwood 2019-09-19 14:17:03 UTC]

I'm seeing this failure as well

Patch that fixes the issue

I have encountered the same problem. It seems that newer pulseaudio headers add const to some pointer parameters making them incompatible with the autogenerated stubs present in qtwebengine (chromium).

As I have no idea how to regenerate the stub file, I have prepared a patch that fixes it instead.

pulseaudio_13.patch

This patch works for me.
Taken from bug #694896

[Comment 7 atosser 2019-09-24 18:01:03 UTC]

Upstream has fixed this issue:

https://codereview.qt-project.org/c/qt/qtwebengine-chromium/+/274842
https://codereview.qt-project.org/c/qt/qtwebengine-chromium/+/274847
https://codereview.qt-project.org/c/qt/qtwebengine-chromium/+/274848

We have to wait for the next release unless a band-aid patch is desired in the tree for the current versions..

Thanks Jan B for the patch can confirm it works.
