Unable to start eCAL-Player or eCAL-Record missing shared libraries: libhdf5.so.103 about ecal HOT 7 CLOSED

Please remove your build folder completely and then rebuild eCAL.
Please also pass -DHDF5_ROOT=/usr when calling cmake, thus calling

cmake .. -DCMAKE_BUILD_TYPE=Release -DECAL_THIRDPARTY_BUILD_PROTOBUF=OFF -DHDF5_ROOT=/usr

I would assume that it will then find the HDF5 version installed in your system (or at least I'd hope so).

Alternatively, you could add home/serov/anaconda3/lib to your LD_LIBRARY_PATH and use the anaconda hdf5 library at runtime.

I did the same on a "naked" Ubuntu 18.04 and ecaL_play is working well. I made a 'ldd' and the output is

Indeed I don't have a link to libhdf5.so.103

This is the tab completion listing for libhdf5_

Could you tell me how to correctly link the right library? I noticed that my installation tries to link libhdf5.so.103 whereas Yours libhdf5_serial.so.100. I am not sure about the exact impact of the different library names and numbers. Moreover I do not have the exact libhdf5.so.103 listed under /usr/lib/x86_64-linux-gnu/

Do you have libhdf5.so.103 somehwere else in your system (but not in the LD_LIBRARY_PATH)?
It would be interesting to see.
Also you can open the CMakeCache.txt file from your build directory and search for HDF5 in this file. It should tell you where CMake found the library.

Indeed I could find libhdf5.so.103 on my system. It is part of the anaconda python installation:

This might be a bit overkill, but here are the lines containingHDF5 in the CMakeCache.txt

What would be the best approach to tackela this problem? Manually link the library? Rebuild eCAL in a different way?

This helped me remove the wrong linkage of libhdf5.so.103 from the anaconda environment however cmake tried to link other libraries to the anaconda path.

I resolved the wrong linkage of libraries by temorarily removing all unwanted folders from PATH before configuring eCAL with cmake .. -DCMAKE_BUILD_TYPE=Release -DECAL_THIRDPARTY_BUILD_PROTOBUF=OFF -DHDF5_ROOT=/usr (described here https://gitlab.com/morpheus.lab/morpheus/issues/3):
echo $PATH
/opt/ros/melodic/bin:/home/serov/anaconda3/bin:/home/serov/anaconda3/condabin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

and then exporting PATH without any unwanted folders, in my case /home/serov/anaconda3/bin and /home/serov/anaconda3/condabin:
export PATH="/opt/ros/melodic/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin"

After that I was able to succesfully configure and build eCAL and run ecal_play or ecal_rec.

Ok, good to hear that it is working for you now 😄
