_pyfreenect2.so: undefined symbol: _ZN12libfreenect29Freenect2D1Ev

[m1lhaus]

Today I downloaded and built fresh libfreenect2 and this Python wrapper. I managed to compile and install libraries (libfreenect2 works). To install pyfreenect I had to modify setup.py like this:

libfreenect2_module = Extension("_pyfreenect2",
    libraries=["/home/milan/Programy/libfreenect2/install/lib/libfreenect2.so"],
    sources=["pyfreenect2.cpp",
        "src/Frame.cpp",
        "src/FrameMap.cpp",
        "src/Freenect2.cpp",
        "src/Freenect2Device.cpp",
        "src/Registration.cpp",
        "src/SyncMultiFrameListener.cpp"],
        extra_compile_args = ["-fpermissive"],
    include_dirs=[numpy.get_include(), "/home/milan/Programy/libfreenect2/install/include"],
    define_macros=[("NPY_NO_DEPRECATED_API", "NPY_1_7_API_VERSION")])

But when I want run pyfreenect2, I am getting this error:

Traceback (most recent call last):
  File "test.py", line 6, in <module>
    import pyfreenect2
  File "/home/milan/Stažené/pyfreenect2-master/pyfreenect2.py", line 1, in <module>
    import _pyfreenect2

Any ideas? Thanks

Any results on this??? Have the same problem myself!

Where did the installer write your libfreenect2.so file to? Or does the installer instead only write out a libfreenect2-0.0.0-py2.7.linux-x86_64.egg file?

@m1lhaus ,I have the similar problem as you .Have you solved the issue?

@Myzhencai No, I ended up using C++ library. But from error name, I would recommend you check you _pyfreenect2.so library for getSPFrameMapFromFrameMap symbol name (just use whatever highperformace text editor you have - not gedit :D). Maybe method fingerprint changed or wrong binary version you are using.

@m1lhaus I will try it ,many thanks .Have a nice day
