I am currently installing OpenCV3.4.4 in ordre to use it with Code::Blocks. I used CMake GUI to Configure and Generates the binaries.
But when I'm using 'mingw32-make' to finish the installation, an error occurs about strnlen which apparently is not define. I have the following message :
" C:\opencv\sources\modules\core\src\persistence.cpp: In function 'char* icvGets(CvFileStorage*, char*, int)': C:\opencv\sources\modules\core\src\persistence.cpp:71:46: error: 'strnlen' was not declared in this scope size_t sz = strnlen(ptr, maxCount); ^ C:\opencv\sources\modules\core\src\persistence.cpp:82:46: error: 'strnlen' was not declared in this scope size_t sz = strnlen(ptr, maxCount); ^ modules\core\CMakeFiles\opencv_core.dir\build.make:901: recipe for target 'modules/core/CMakeFiles/opencv_core.dir/src/persistence.cpp.obj' failed mingw32-make[2]: * [modules/core/CMakeFiles/opencv_core.dir/src/persistence.cpp.obj] Error 1 CMakeFiles\Makefile2:1671: recipe for target 'modules/core/CMakeFiles/opencv_core.dir/all' failed mingw32-make[1]: * [modules/core/CMakeFiles/opencv_core.dir/all] Error 2 Makefile:161: recipe for target 'all' failed mingw32-make: *** [all] Error 2"

I've read some other forum asking to change some variables in CMake GUI but for other issues and I did not succeed to find the same as me. I hope that someone could help me. thank you
