edit

System information (version)

• OpenCV => 3.4
• Operating System / Platform => Windows 10 64 Bit
• Compiler => GCC/G++ 4.9.3 (MinGW 64)

Detailed description

I receive the following linking error when trying to compile OpenCV 3.4 on Windows 10 with MinGW 64.

[ 41%] Linking CXX shared library ../../bin/libopencv_core340.dll
C:/Rtools/mingw_64/bin/../lib/gcc/x86_64-w64-mingw32/4.9.3/../../../../x86_64-w64-mingw32/bin/ld.exe: i386 architecture of input file `CMakeFiles/opencv_core.dir/objects.a(vs_version.rc.obj)' is incompatible with i386:x86-64 output 
collect2.exe: error: ld returned 1 exit status 
make[2]: *** [bin/libopencv_core340.dll] Error 1
make[1]: *** [modules/core/CMakeFiles/opencv_core.dir/all] Error 2 
make: *** [all] Error 2

Steps to reproduce

Cmake command:

cmake -G "Unix Makefiles" -DCMAKE_C_COMPILER=C:/Rtools/mingw_64/bin/gcc.exe -DCMAKE_CXX_COMPILER=C:/Rtools/mingw_64/bin/g++.exe -DENABLE_PRECOMPILED_HEADERS=OFF -DBUILD_opencv_world=OFF -DBUILD_opencv_contrib_world=OFF -DBUILD_matlab=OFF -DPYTHON_EXECUTABLE=OFF -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=../../../opencv/ ../

Cmake output:
