> The reason you see all that other noise about not finding other libs
is because once the scoperunner runs into an issue with one lib
(libschnasni.username_schnasni.so in this case), it then attempts to
find alternatives that it may have more luck with.

I did this after Michal applied a lot of pressure to allow short names
for scope libraries. Originally, you had to use the full-qualified scope
ID with a .so suffix. In effect, this has created aliasing for the
possible .so names, meaning that the scope loader has to look for a
whole bunch of possible names.

Next time, I'll be resisting that kind of suggestion a lot more. In the
long run, I think it creates more trouble than it's worth.

Title:
  Undefined symbol when running scope in emulator

Status in Client Developer Experience:
  New
Status in unity-scopes-api package in Ubuntu:

Bug description:
  I'm trying to run the template scope in the emulator of the Ubuntu SDK
  in 15.04. The scope builds just fine, but when I try to run it in the
  emulator, it gives me the following error:

  scoperunner: unity::ResourceException: Cannot load scope schnasni.username_schnasni; tried in the following locations:
  /opt/click.ubuntu.com/schnasni.username/0.1/schnasni/i386-linux-gnu/libschnasni.username_schnasni.so

  It searches for the file in 6 directories, and does not find it in 5
  of these, which is expected I think. But what does

  undefined symbol:
  _ZN5unity6scopes9ScopeBase22activate_result_actionERKNS0_6ResultERKNS0_14ActionMetadataERKS

  mean and how can I resolve it?
