Hello,
I am trying to configure opencv 'opencv-3.4.1-vc14_vc15.exe' on my CodeBlocks 17.12 through this tutorial: https://zahidhasan.github.io/2017-03-25-How-to-install-OpenCV-3.2-in-windows-10-using-MinGW-(64)-and-Codeblocks/
When I open CMake and make all required setups, I tried configure CodeBlocks - MinGW MakeFiles. After a few seconds I got this error:
CMake Error at C:/CMake/share/cmake-3.11/Modules/CMakeMinGWFindMake.cmake:12 (message): sh.exe was found in your PATH, here:
C:/Users/Mikael/Anaconda3/Library/usr/bin/sh.exe
For MinGW make to work correctly sh.exe must NOT be in your path.
Run cmake from a shell that does not have sh.exe in your PATH.
If you want to use a UNIX shell, then use MSYS Makefiles.
Call Stack (most recent call first): CMakeLists.txt:127 (project)
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage Configuring incomplete, errors occurred!
Of course, I can try delete sh.exe from my path. I am worried about my Python/Anaconda and unexpected consequences as well. Is any possibility to get working both in the same time ? Currently I am coding the most time in python. But I'm forced to consider using c / c ++ for better performance.
I have tried ignoring this problem and just try generate again.

After all, i tried build it from codeblocks and got this: build log: C:\opencv\sources\3rdparty\protobuf\src\google\protobuf\stubs\io_win32.cc:94:3: warning: identifier 'nullptr' is a keyword in C++11 [-Wc++0x-compat] return s == nullptr || s == 0; ^ C:\opencv\sources\3rdparty\protobuf\src\google\protobuf\stubs\io_win32.cc: In function 'bool google::protobuf::internal::win32::{anonymous}::null_or_empty(const char_type)': C:\opencv\sources\3rdparty\protobuf\src\google\protobuf\stubs\io_win32.cc:94:15: error: 'nullptr' was not declared in this scope return s == nullptr || s == 0; ^ mingw32-make.exe[2]: [3rdparty/protobuf/CMakeFiles/libprotobuf.dir/src/google/protobuf/stubs/io_win32.cc.obj] Error 1 mingw32-make.exe[1]: [3rdparty/protobuf/CMakeFiles/libprotobuf.dir/all] Error 2 mingw32-make.exe: ** [all] Error 2 3rdparty\protobuf\CMakeFiles\libprotobuf.dir\build.make:258: recipe for target '3rdparty/protobuf/CMakeFiles/libprotobuf.dir/src/google/protobuf/stubs/io_win32.cc.obj' failed mingw32-make.exe[2]: Leaving directory 'C:/opencv/build' CMakeFiles\Makefile2:710: recipe for target '3rdparty/protobuf/CMakeFiles/libprotobuf.dir/all' failed mingw32-make.exe[1]: Leaving directory 'C:/opencv/build' C:/opencv/build/Makefile:161: recipe for target 'all' failed Process terminated with status 2 (4 minute(s), 24 second(s)) 4 error(s), 4 warning(s) (4 minute(s), 24 second(s))
Can you somebody help me please ?
