System information (version)

• OpenCV => 4.4.0
• Operating System / Platform => Windows 64 Bit
• Compiler => mingw32

Detailed description

The symbol "scr1" is already defined in the mingw-w64 runtime package in "mingw-w64\x86_64-8.1.0-posix-seh-rt_v6-rev0\mingw64\x86_64-w64-mingw32\include\dlgs.h" (included through "windows.h" for example).

Steps to reproduce

The compilation fails.

Several ways to solve this issue

1. The ugliest one would be to add at the beginning of this file:

#if defined scr1
#  undef scr1
#endif  // scr1

2. A better one should be to avoid including the "windows.h" file before "color_yuv.simd.hpp"

3. An alternative could be the renaming of variables.
