Error while loading the library event after export LD_LIBRARY_PATH [closed]

When i execute one necessary step in my project:

ubuntu@cscsh:~$ soss dds_to_ros2.yaml \Error while loading the library ["/home/dbt/rosis_workspace/soss/install/soss-dds/lib/soss/dds/../../libsoss-dds.so"]: /home/dbt/rosis_workspace/soss/install/soss-dds/lib/soss/dds/../../libsoss-dds.so: undefined symbol: _ZTVN8eprosima8fastrtps28DisablePositiveACKsQosPolicyECould not find system handle for middleware of type [dds]Failed to load middlewares!

So i do this:

ubuntu@cscsh:~/rosis_workspace/soss/install/soss-dds/lib$ ldd libsoss-dds.so     linux-vdso.so.1 (0x00007fff5ef61000)    libfastrtps.so.1 => /home/dbt/ros2_ws/src/eProsima/install/fastrtps/lib/libfastrtps.so.1 (0x00007f8ae4179000)    libsoss-core.so => /home/dbt/rosis_workspace/soss/install/soss-core/lib/libsoss-core.so (0x00007f8ae3de1000)    libyaml-cpp.so.0.5 => /usr/lib/x86_64-linux-gnu/libyaml-cpp.so.0.5 (0x00007f8ae3b67000)    libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f8ae3948000)    libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f8ae35bf000)    libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f8ae33a7000)    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f8ae2fb6000)    libfastcdr.so.1 => /home/dbt/ros2_ws/src/eProsima/install/fastcdr/lib/libfastcdr.so.1 (0x00007f8ae2da3000)    libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f8ae2b9f000)    libtinyxml2.so.6 => /usr/lib/x86_64-linux-gnu/libtinyxml2.so.6 (0x00007f8ae298b000)    /lib64/ld-linux-x86-64.so.2 (0x00007f8ae4aae000)    libboost_program_options.so.1.65.1 => /usr/lib/x86_64-linux-gnu/libboost_program_options.so.1.65.1 (0x00007f8ae270a000)    libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f8ae236c000)

then execute command

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/dbt/ros2_ws/src/eProsima/install/fastrtps/libubuntu@cscsh:~/ros2_ws/src/eProsima$ echo $LD_LIBRARY_PATH/home/dbt/rosis_workspace/soss/install/soss-ros2-test/lib:/home/dbt/rosis_workspace/soss/install/soss-ros2/lib:/home/dbt/rosis_workspace/soss/install/soss-mock/lib:/home/dbt/rosis_workspace/soss/install/soss-json/lib:/home/dbt/rosis_workspace/soss/install/soss-dds/lib:/home/dbt/rosis_workspace/soss/install/soss-core/lib:/home/dbt/ros2_ws/src/eProsima/install/fastcdr/lib:/home/dbt/ros2_ws/src/eProsima/install/fastrtps/lib

But when i execute: soss dds_to_ros2.yaml.The same error message still exists.Does anyone know what is wrong with this?
