I installed opencv 4.1.0 using the following modified installer it worked perfect (you only need to increase memory swap - I increased it to 8GB).
install_opencv4.1.0_Nano.sh (here is the following code for your use by the end of this post - without swap modification).
I made some modification in the original file, one of them is that i skipped installing python 2 binding if someone need it change the flag -D BUILD_opencv_python2=OFF to ON).
After installation, when running opencv c++ code using cmake and CMakeLists.txt (as recommended by opencv) everything works perfectly (i tested opencv version and get 4.1.0), I’ve tested cuda acceleration with opencv and it works, perfectly. i tested python 3 as well and everything works good.
I downloaded and install latest code::blocks IDE, and tested the hello world with native GCC compiler (default).
when trying to link opencv and use this IDE nothing works, no auto-complete, build errors etc.
i set the following:
- compiler search directories: /usr/local/include/opencv4/
- linker tab - usr/local/bin/
- tried list of libs.
I’ll appreciate if someone will try the installer below, and provide instructions (for dummies), how to link latest code:blocks IDE with this opencv installation that can be build and run\debug using it, with autocomplete.
