无法在 qt creator 上链接 c++ 上的 realsense 库

Question

I am trying basic C++ programs with Intel Realsense sdk2 with librealsense library on Qt Creator. My .pro file looks like the following

INCLUDEPATH += /home/magbot/opencv-3.4.8/build/include
LIBS += -L/home/magbot/opencv-3.4.8/build/lib \
-lopencv_core \
-lopencv_highgui \
-lopencv_imgcodecs \

LIBS += -L/usr/lib/x86_64-linux-gnu -lrealsense2 \

SOURCES += \
    main.cpp

OpenCV libraries compile fine but the realsense library does not link. I get this error error: cannot find -lrealsense2 . The folder /usr/lib/x86.... contains the file librealsense2.so but its in red. Please help...where am I doing it wrong

Answer 1

It seems that there is some error with your installation. I checked with Ubuntu 16.04 and 18.04. Both installation looks fine installed via package manager.

You should try reinstalling it. If you want to install it with package manager(apt-get) follow this

If you are installing from source code that follow this

As mention in comment by KamilCuk , you can also try to remove dead symbolic link and then create new one.

rm /usr/lib/x86.../librealsense2.so
ln -s /usr/lib/x86.../librealsense2.so.2.30 /usr/lib/x86.../librealsense2.so
