[RUNTIME ERROR OPENVINO] error while loading shared libraries: libinference_engine_transformations.s

[alexandrepires5]

Hello to everyone, 

I have the following problem regarding 2020.3 version of openvino. I am trying to include openvino in a custom project and it is occurring the following runtime error: 

main: error while loading shared libraries: libinference_engine_transformations.so: cannot open shared object file: No such file or directory

I am building the detector as a library. The cmakelist is the following:

project(detector)
find_package(InferenceEngine REQUIRED)
find_package(OpenCV REQUIRED)
include_directories(${InferenceEngine_INCLUDE_DIRS})
add_library(${PROJECT_NAME} STATIC Detector.cpp ../../include/Detector/Detector.h)
add_library(lib::detector ALIAS ${PROJECT_NAME})

target_link_libraries(${PROJECT_NAME} PUBLIC
        ${InferenceEngine_LIBRARIES}
        ${OpenCV_LIBS})

I have already sourced the environment and its pointing to the lib location of all .so files(where libinference_engine_transformations.so is located). I can build the project no problem. The samples work without any issues. I am currently using UBUNTU 18.04 VM with an core i7.

Am I missing a step somewhere? I am building using CLion and the terminal(both gave the same error.)

UPDATE: Doing an ldd on the runtime app, shows this:

I solved my own problem over this... Just need to add the lib path to /etc/ld.so.conf file:

include /etc/ld.so.conf.d/*.conf
/opt/intel/openvino_2020.3.194/deployment_tools/ngraph/lib/
/opt/intel/openvino_2020.3.194/deployment_tools/inference_engine/lib/intel64/

and update it with:

sudo ldconfig

Me funcionó perfecto, gracias por compartirlo!

En mi caso estoy corriendo desde un Raspberrypi 3 B+, entonces estos fueron los comandos que utilicé:

sudo nano /etc/ld.so.conf

include /etc/ld.so.conf.d/*.conf
/opt/intel/openvino/deployment_tools/ngraph/lib/
/opt/intel/openvino/deployment_tools/inference_engine/lib/armv7l

Y luego actualizar con:

sudo ldconfig
