Set LD_LIBRARY_PATH correctly

I am using Docker with image of Ubuntu 16.04. I am using this docker to run: - Import C++ classes in python with the help of boost.python - Import matlab's python package in python with the help Matlab Runtime (MCR). Before I have installed MCR in the docker, I have installed boost using: $ sudo apt-get install -y libboost-all-dev and I was able to wrap C++ classes and call them in python. Then I have installed MCR and one of the requirement is to set LD_LIBRARY_PATH to Matlab's library. export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/MATLAB/MATLAB_Runtime/v94/runtime/glnxa64:/usr/local/MATLAB/MATLAB_Runtime/v94/bin/glnxa64:/usr/local/MATLAB/MATLAB_Runtime/v94/sys/os/glnxa64:/usr/local/MATLAB/MATLAB_Runtime/v94/extern/bin/glnxa64 It worked, I was able to run matlab's python package in python but testing the C++ classes wrappers failed due to change of LD_LIBRARY_PATH. For example, I get the following error when I try to import C++ class in python: /usr/lib/x86_64-linux-gnu/libpython3.4m.so.1.0: undefined symbol: XML_SetHashSalt If I unset LD_LIBRARY_PATH C++ import works but MCR fails. So the question what LD_LIBRARY_PATH should be in order to run both C++ classes and Matlab's python package successfully? I have tried to add path to boost libraries to LD_LIBRARY_PATH but didn't work, so the env value would be: /usr/lib/x86_64-linux-gnu:/usr/local/MATLAB/MATLAB_Runtime/v94/runtime/glnxa64:/usr/local/MATLAB/MATLAB_Runtime/v94/bin/glnxa64:/usr/local/MATLAB/MATLAB_Runtime/v94/sys/os/glnxa64:/usr/local/MATLAB/MATLAB_Runtime/v94/extern/bin/glnxa64 **EDIT** the dependencies of C++ library file before setting the LD_LIBRARY_PATH: linux-vdso.so.1 (0x00007ffcee0dc000) libpython3.4m.so.1.0 => /usr/lib/x86_64-linux-gnu/libpython3.4m.so.1.0 (0x00007f9d69e59000) libboost_python-py34.so.1.55.0 => /usr/lib/x86_64-linux-gnu/libboost_python-py34.so.1.55.0 (0x00007f9d69c09000) libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f9d698fe000) libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f9d695fd000) libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f9d693e7000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f9d6903c000) librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007f9d68e34000) libexpat.so.1 => /lib/x86_64-linux-gnu/libexpat.so.1 (0x00007f9d68c0b000) libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007f9d689f0000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f9d687d3000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f9d685cf000) libutil.so.1 => /lib/x86_64-linux-gnu/libutil.so.1 (0x00007f9d683cc000) /lib64/ld-linux-x86-64.so.2 (0x00007f9d6a6c3000) After setting the LD_LIBRARY_PATH: linux-vdso.so.1 (0x00007ffc42e9b000) libpython3.4m.so.1.0 => /usr/lib/x86_64-linux-gnu/libpython3.4m.so.1.0 (0x00007fad9635b000) libboost_python-py34.so.1.55.0 => /usr/lib/x86_64-linux-gnu/libboost_python-py34.so.1.55.0 (0x00007fad9610b000) libstdc++.so.6 => /usr/local/MATLAB/MATLAB_Runtime/v94/sys/os/glnxa64/libstdc++.so.6 (0x00007fad95d8a000) libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fad95a89000) libgcc_s.so.1 => /usr/local/MATLAB/MATLAB_Runtime/v94/sys/os/glnxa64/libgcc_s.so.1 (0x00007fad95873000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fad954c8000) librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007fad952c0000) libexpat.so.1 => /usr/local/MATLAB/MATLAB_Runtime/v94/bin/glnxa64/libexpat.so.1 (0x00007fad95095000) libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007fad94e7a000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fad94c5d000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007fad94a59000) libutil.so.1 => /lib/x86_64-linux-gnu/libutil.so.1 (0x00007fad94856000) /lib64/ld-linux-x86-64.so.2 (0x00007fad96bc5000)
