l_openvino_toolkit_p_2020.1.023 CMake Error

[Kaliyappan__Malathi]

Hi,

I am working on pedestrian_tracker_demo in OpenVINO (l_openvino_toolkit_p_2020.1.023). I had already worked in pedestrian tracker in 2019 R1 version. Since I faced memory leak issue I started working with 2020.1 version.

I was using libcurl in 2019 R1 version to alert me when ever I see a pedestrian, Please find the CMake file ( CMakeLists.txt ) attached below (The libcurl is statically linked)

Here I also attached the CMake file for 2020.1 version(Please check CMakeLists_2020.txt with libCurl statically linked, but did not work)

I tried to use the old CMake file(2019 R1) in 2020.1 vesion , The reason to use is statically link the libcurl(as I did not know, how to link in the 2020.1 CMAKE ).

Can you please advise me how to link the libCurl to the CMAKE file.

Please find the Error Message,

Hi Malathi,

You can add the below commands in <path_to_openvino>/deployment_tools/open_model_zoo/demos/CMakeLists.txt to link curl package

[Ln 157]:

FIND_PACKAGE(CURL REQUIRED)

Modify [Ln 185]:

target_link_libraries(${IE_SAMPLE_NAME} PRIVATE ${OpenCV_LIBRARIES} {InferenceEngine_LIBRARIES} ${IE_SAMPLE_DEPENDENCIES} gflags -lcurl)

I have successfully built pedestrian_tracker_demo with libcurl by adding the mentioned commands.

Please give a try and let me know if it works.

Regards,
