Hello. I am encountering some problems while trying to use cmake to compile the source code taken from github. ([GitHub - opencv/opencv: Open Source Computer Vision Library](https://github.com/opencv/opencv)) After I configure and generate in cmake, when I use the mingw32-make command in the build folder, it fails at 11%: `[11%] Building RC object modules/core/CMakeFiles/opencv_core.dir/vs_version.rc.obj gcc: error: \(1\)\opencv-master\modules\core\include: No such file or directory gcc: error: \(1\)\opencv-master\3rdparty\zlib: No such file or directory gcc: error: \(1\)\opencv-master\3rdparty\include\opencl\1.2: No such file or directory D:\mingw64\mingw64\bin\windres.exe: preprocessing failed. mingw32-make[2]: ***[modules\core\CMakeFiles\opencv_core.dir\build.make:1661: modules/core/CMakeFiles/opencv_core.dir/vs_version.rc.obj] Error 1 mingw32-make[1]:*** [CMakeFiles\Makefile2:1776: modules/core/CMakeFiles/opencv_core.dir/all] Error 2 mingw32-make: *** [Makefile:165: all] Error 2` I use cmake 3.20.0. How can I remediate this? Thanks! ---

opencv version ? mingw version ? so, this happens, while building the libs ? can you show a bit more output around the error(s), please ? ---

mingw64 6.0; opencv the one in the github repo, to be honest I do not know what version it is. That’s all the output in the error, I’ll try and build again and show upper output in a bit, but its only “Building…” This happens, after I press configure, generate in cmake, and then I go in cmd into the folder that I generated it into, and do the command mingw32-make ---

can you try a more recent mingw ? (it all works fine for me, using opencv master and mingw 8.1.0) > [@brev404](#): > > This happens, after I press configure, generate in cmake, and then I go in cmd into the folder that I generated it into, and do the command mingw32-make yea, that’s how we do it. nothing wrong ---

Sure, i’ll update my complier and try again ---
