previous definition of `PanelConnector' was here (building 0.6 bzr)

[Graham Rogers]

I am attempting to build awn from the 0.6 branch and came upon this error:

awn-panel-connector.vapi:6.2-6.46: error: `Awn' already contains a definition for `PanelConnector'
 public interface PanelConnector : GLib.Object {
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
awn-panel-connector.vala:23.3-23.41: note: previous definition of `PanelConnector' was here
  public interface PanelConnector: Object
  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Compilation failed: 1 error(s), 0 warning(s)
make[2]: *** [awn-panel-connector.c] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

Looking in the two files, it seems there is a mismatch in the definition of the interace 'PanelConnector'. In awn-panel-connector.vapi it is "public interface PanelConnector : GLib.Object", however in awn-panel-connector.vala it is "public interface PanelConnector : Object"

Changing the second definition to use GLib.Object allowed me to finish the build.

0.6 branch doesn't like parallel build, I think that's the issue you're actually seeing... Still what vala version are you using?

[Graham Rogers (grogers3-14)]

It seems to be fixed now. Maybe in a recent revision, I'm not sure. My vala version is 0.8.1, though it is probably not required now.

[Michal Hruby (mhr3)]

It's not fixed, as I said it's a problem in the build system, sometimes it'll work, other times not, we need to fix it.

[Graham Rogers (grogers3-14)]

Your right see http://aur.archlinux.org/packages.php?ID=12294 - sometimes it works, sometimes it doesn't.

I have just looked in the branch and it does seem that the difference is there i.e. GLib.Object in the .vapi and Object in the .vala. Are they meant to be different, or does one of them need to be changed?

[Michal Hruby (mhr3)]

The vala code is fine, build system is screwed...

Still, 0.6 branch is highly experimental, (mostly) stable development is still going on in 0.4/trunk branch. Making 0.6 packages/aur is not a good idea at this point.
