Hi I am installing in Ubuntu Linux 16.04. and I get errors as shown below
zayyon@zayyon-MS-7693:~/zayyon/HandTracker-master$ ./runme.shMBV_LIBS Environment variable should point to the MBV libraries folder.
MBV_LIBS /home/zayyon/zayyon/MBV_PythonAPI_Linux_1.1/
Setting LD_LIBRARY_PATH and PYTHONPATH
Running the Single Hand Tracker script...
Traceback (most recent call last):
File "src/SingleHandTracking.py", line 8, in

ImportError: /home/zayyon/zayyon/MBV_PythonAPI_Linux_1.1//libs/libCore.so: undefined symbol: _ZN2cv9ExceptionC1EiRKSsS2_S2_i
We have not tested with Ubuntu 16.04 yet. It should work if you have the correct versions of the required libs.
From the error it looks like a version problem with opencv (cv::Exception).
The packaged mbv libs (including libCore.so) are compiled with opencv 2.4.8.
Do I need to install opencv 2.4.8 ?
OpenCV 2.4.8 is the version packaged with ubuntu 14.04.
I believe any 2.4.x version should work.
My opencv version is 2.4.9.1
Strange, since cv::Exception should be the same in all 2.4.x version. I any case, you could try using 2.4.8 or test on ubuntu 14.04.
I was having the same issue on ubuntu 15.10, I think it might be the same issue reported here #2, I gave up and went for an earlier Ubuntu version, as I was not able to get OpenCV with Python to compile with an older gcc version as suggested there.
I have the similar problem too with 2.4.8 on Ubuntu 16.04. Could you tell with what libraries version you complied project?
