[Debian-med-packaging] Bug#788209: underlinked: undefined symbol cvCalcOpticalFlowHS

[IOhannes m zmoelnig]

Package: sitplus
Version: 1.0.3-4.1
Severity: important

Dear Maintainer,

sitplus (or rather it's "vision" module) has unresolved symbols.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

after a fresh install, i do:
- $ sitplus
- Menu: Activity->Start...
- use default values (camera tracker enabled), and click on
  "OK"
- in the activity manager click on "Play"

   * What was the outcome of this action?

sitplus closes; on the stderr i get:
> sitplus: symbol lookup error: /usr/lib/sitplus/libspmod_vision.so: undefined symbol: cvCalcOpticalFlowHS

   * What outcome did you expect instead?

no crash.

a quick grep revealed that the cvCalcOpticalFlowHS is exported in
libopencv_legacy.so

and indeed the following works (afaict):

    LD_PRELOAD=libopencv_legacy.so sitplus

please link the relevant binaries against libopencv_legacy.so
