opencv installation failed

[jimmy-adams]

Dear all,

I want to use the vitis vision library with Vitis 2022.2. But when i installed and compiled the needed opencv library in ubuntu 18.04, the cmake generates errors listing like below: opencv/opencv/build$ sudo cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/media/x2-b7010/data02/opencv/opencv/install -D CMAKE_CXX_COMPILER=/media/x2-b7010/data02/xilinx/Vitis_HLS/2022.2/tps/lnx64/gcc-6.2.0/bin/g++ -D OPENCV_EXTRA_MODULES_PATH=/media/x2-b7010/data02/opencv/opencv_contrib/modules/ -D WITH_V4L=ON -D BUILD_TESTS=OFF -D BUILD_ZLIB=ON -D BUILD_JPEG=ON -D WITH_JPEG=ON -D WITH_PNG=ON -D BUILD_EXAMPLES=OFF -D INSTALL_C_EXAMPLES=OFF -D INSTALL_PYTHON_EXAMPLES=OFF -D WITH_OPENEXR=OFF -D BUILD_OPENEXR=OFF . -- The CXX compiler identification is GNU 6.2.0 -- The C compiler identification is GNU 6.2.0 -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - failed -- Check for working CXX compiler: /media/x2-b7010/data02/xilinx/Vitis_HLS/2022.2/tps/lnx64/gcc-6.2.0/bin/g++ -- Check for working CXX compiler: /media/x2-b7010/data02/xilinx/Vitis_HLS/2022.2/tps/lnx64/gcc-6.2.0/bin/g++ - broken CMake Error at /usr/local/share/cmake-3.22/Modules/CMakeTestCXXCompiler.cmake:62 (message): The C++ compiler

is not able to compile a simple test program.

It fails with the following output:

There is a case i need to mention. I have multiple vitis and vivado suite in my host machine: Vivado 2018(/usr/local/Xilinx/Vitis/2019.2/) Vitis 2019(/media/x2-b7010/data02/xilinx_2018/SDK/2018.3/) Vitis 2022(/media/x2-b7010/data02/xilinx/Vitis/2022.2/)

I am not sure if this case leads to my failed compiling.

Hello @jimmy-adams ,

Please make sure you ran step 5 of opencv-installation guidance

If yes, and still you face errors, try updating the same for LD_LIBRARY_PATH too
