Linking libnote_sound.a fails on OSX / ports

[Klaus Halfmann]

I try to update or compile bzr8309[trunk]

trunk klaus$ ./compile.sh

maybe I have to add some (new) library via the ports mechanism?

SirVer / Gun: what was the last Branch mereged here?
SirVer: can you confim?

Anyone else with OSX ports?

Offending commit:

http://bazaar.launchpad.net/~widelands-dev/widelands/trunk/revision/8312

I removed the dependencies from sound to logic and wui. I might have missed including/removing a header somewhere that Travis and AppVeyor had no problem with.

[Klaus Halfmann (klaus-halfmann)]

Maybe I must delte some CMake magic cache?

[GunChleoc (gunchleoc)]

You could try deleting the build directory, that will empty the cmake cache for your branch.

[Klaus Halfmann (klaus-halfmann)]

Now trying with a fresh copy (which will deltet the build directory as well)

bzr branch lp:widelands
cd widelands/
./compile.sh

[Klaus Halfmann (klaus-halfmann)]

Look like we need a dummy note_sound.cc as (my) CMake will get confused.
Branch is compiling ...

[GunChleoc (gunchleoc)]

Fixed in build20-rc1
