Support / Migrate to Vuforia 5 (error: undefined reference)
« on: March 31, 2016, 12:03:35 pm »
Hi all, I'm using https://github.com/sidneibjunior/vuforia-jpct as my base, and have successfully migrated to Vuforia 3.0.9 without major problem.
Now I'm trying to migrate to Vuforia 5.0.5, but I got this error while building my codes:

[armeabi-v7a] Compile++ arm  : ImageTargetsNative <= ImageTargets.cpp
[armeabi-v7a] SharedLibrary  : libImageTargetsNative.so
jni/ImageTargets.cpp:92: error: undefined reference to 'QCAR::ObjectTracker::getClassType()'
jni/ImageTargets.cpp:159: error: undefined reference to 'QCAR::ObjectTracker::getClassType()'
jni/ImageTargets.cpp:178: error: undefined reference to 'QCAR::ObjectTracker::getClassType()'
jni/ImageTargets.cpp:190: error: undefined reference to 'QCAR::ObjectTracker::getClassType()'
collect2: error: ld returned 1 exit status
make: *** [obj/local/armeabi-v7a/libImageTargetsNative.so] Error 1

---

Has anyone ever face the same problem? Or have successfully migrate to Vuforia 5? Please help... I really need to migrate.
I have tried to follow this instruction: https://developer.vuforia.com/library/articles/Solution/How-to-Migrate-an-Android-Project
But somehow still end up in "undefined reference" error... I don't know much about C++, but I need to use the native code for my project.

Thanks in advance.
