[LMMS-devel] master does not build anymore on Ubuntu 14.04

Hi,

I cannot build lmms from master for 3 days now:

* Fresh git clone
* Build error:

Any hint, someone?

That would coincide with Zyn dependency cleanup as well as some GCC6
changes.

My instinct is the Zyn stuff may have caused this, which is surprising
since 12.04 isn't complaining...

Can you try to revert commits 60740fb, a06cb01?

If either fix it, please post in #2747 or #2749, respectively (or feel free
to open a bug report on it).

If neither fix it, take a look through the commit logs and see if there's
one that strikes a cord: https://github.com/LMMS/lmms/commits

Hi Tres,

Reverting the commit 60740fb makes the build succeed.
I will post in #2747 as you suggest.
Thanks a lot for your prompt answer.
Debugging on a non-functionnal build is very difficult, you know!;-)
