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
