Bug Description

unity-system-compositor can't build against Mir 0.6/0.7: undefined reference to `...@MIR_CLIENT_8'

I've tried with both the usc trunk and devel-next branches. Neither is buildable any more...

Fixed (in USC at least) by adding "Requires.private: mirclient" in src/server/mirserver.pc.in

How is it that this built in the silo successfully? (and I was on the lookout for it due to the newly-introduced platform versioning).

Not really fixed still :(

But I found the cause. A second fix is coming for USC --> bug 1355609

Daniel, how do you repro this exactly?
Next time, can you please add your commit for a fix found during a release to the MP (devel-mir-next --> trunk) that's (likely) already up and being reviewed?

Sorry for the confusion. Most of the 0.7.0 series got merged into 0.6.0 at a late stage. I've verified everything in 0.6.0 is also fixed in 0.7.0. So although the branched fixes in 0.7.0 have not been "released" yet, the equivalent fixes in 0.6.0 have. No need to mention them in 0.7 any more.

Changed in mir:
milestone:	0.7.0 → none
status:	Fix Committed → Fix Released
