Bug 706376 – dev-util/electron-2.0.17-r2 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*)’

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Matthew "Archer" Vaughn 2020-01-25 23:56:28 UTC]

Electron bundles its own sources for chromium, and these sources contain a dependency on functions exported from pulseaudio. Since stabilization of pulseaudio-13 and removal of pulseaudio-12, electron cannot build because the exported function signatures have changed.

This failure is identical to those previously documented and resolved in bugs #694896 and #694960. The patches provided in those bugs, however, do not successfully apply in the electron ebuild due to the bundled version of chromium (61) differing from the target version of those patches (77).

A Gentoo forums user described and resolved this problem, at the URL in the header of this bug report, in a manner similar to those of the other referenced bugs.

To be attached: failing build log, resolving patch, and resolving ebuild.

Reproducible: Always

Steps to Reproduce:
1. emerge '=media-sound/pulseaudio-13.0'
2. emerge '=dev-util/electron-2.0.17-r2'
Actual Results:  
Build fails with a misleading call stack implicating eninja. Actual failure is contained in the build log, when compiling object pulse_stubs.o --

FAILED: obj/media/audio/audio/pulse_stubs.o
...
gen/media/audio/pulse/pulse_stubs.cc:148:27: error: conflicting declaration of C function ‘pa_context_state_t pa_context_get_state(pa_context*)’

Expected Results:  
Previously discovered instances of the same build-breaking behavior traceable to PA13 in chromium and qtwebengine should already have been applied to this package because it is known to bundle chromium sources and depend on pulseaudio, thereby preventing the issue.

proposed patch (secondary)

Astonishingly, the original bug for which this report was opened conceals a second trivial error in one of the DOM files at chromium/third_party/WebKit/Source/core/dom/Document.cpp.

A semicolon is missing. That is all.

Since you can't actually validate that the original bug is resolved without completing a successful build, and since this secondary issue is so trivial, I am including the proposed patch for that as well.

If this package had a maintainer and we were able to use a supported release (upstream is at 7.1.10, now) instead of one that is shipping obviously broken source dependencies, maybe we wouldn't have this problem. Shall I volunteer if no one else is willing? If that is not an acceptable option, what are the necessary qualifications and what is the reason no one has risen to meet them?

[Comment 6 Jonas Stein 2020-01-26 11:37:46 UTC]

You can build and test on your machine and simply prepare a pull request on github. Bots will make additional tests.
If you want to be the responsible person permanently, you can choose to become a proxied maintainer. But you can also just do a single pull request.

[Comment 7 Jonas Stein 2020-01-26 18:26:04 UTC]

Thank you for your contribution. I had a short look on the ebuild. 
Here a few ideas:

* Please test the ebuild with repoman full -d -x https://wiki.gentoo.org/wiki/Repoman
* We always try to use the latest EAPI, please bump to EAPI=7
* please fix the header. (see /usr/portage/skel.ebuild and https://devmanual.gentoo.org/ebuild-writing/eapi/)
* A bot can look for additional mistakes, if you upload a PR via github

* we are in progress to remove python 2
PYTHON_COMPAT=( python2_7 )
Can you make the package to run on python 3?
