- ABI summary:
  . mirclient ABI unchanged at 9
  . mirserver ABI bumped to 41
  . mircommon ABI unchanged at 6
  . mirplatform ABI bumped to 12
  . mirprotobuf ABI unchanged at 3
  . mirplatformgraphics ABI bumped to 10
  . mirclientplatform ABI unchanged at 5

by default in favor of GLESv2).
  . Introduced new buffer semantics (NBS) and enabled it by default.
  . Avoided using libmirserver in mir_demo_standalone_render_overlays,
making bringup traces less cluttered.

Updated the bug description. Now I see mock_egl.cpp in there I suspect
this might be fixed by bug 1603303.

[Bug 1601810] Re: ftbfs in linking libmir-test-assist.a in xenial+overlay and yakkety+overlay

[Alan Griffiths]

That explanation sounds incomplete. libmirserver.so really shouldn't be
mentioning gmock templates.

And "target_link_libraries(mir_acceptance_tests" also mentions libmir-
test-assist.a before libmirserver.so.

But if the solution works...

[Bug 1601810] Re: ftbfs in linking libmir-test-assist.a in xenial+overlay and yakkety+overlay

[Kevin DuBois]

The problem would only occur when using dpkg-buildpackage. (slightly
different link order was generated).

The symbols that were missing were templates from gmock that were
generated and in the mock_egl.cpp.o file. Given the right link order
(namely, mirserver.so before libmir-test-assist.a), things would resolve
correctly. If mirserver.so came after libmir-test-assist.a, then the egl
functions would get resolved, but for whatever reason, the weak symbols
generated as part of the gmock stuff wouldn't get pulled in again before
getting to the end of the linkage list.

The proper solution seems to be to use -Wl,--whole-archive to make sure
that the symbols generated from the gmock templates are still available
despite linkage order

[Alan Griffiths]

As we want to test libmir-test-assist.a for downstream use linking to
the static library instead is not an acceptable solution.
