I want start playing with the OpenCV library, but I have a problem during the build process. I am on Windows 10 with the Mingw compiler. When I launch the command mingw32-make after a while, I get the following errors:
C:\Github\opencv\modules\videoio\src\cap_dshow.cpp:337:21: fatal error: strsafe.h: No such file or directory
#include <strsafe.h>
^
compilation terminated.
modules\videoio\CMakeFiles\opencv_videoio.dir\build.make:187: recipe for target 'modules/videoio/CMakeFiles/opencv_videoio.dir/src/cap_dshow.cpp.obj' failed
mingw32-make[2]: *** [modules/videoio/CMakeFiles/opencv_videoio.dir/src/cap_dshow.cpp.obj] Error 1
CMakeFiles\Makefile2:4340: recipe for target 'modules/videoio/CMakeFiles/opencv_videoio.dir/all' failed
mingw32-make[1]: *** [modules/videoio/CMakeFiles/opencv_videoio.dir/all] Error 2
Makefile:159: recipe for target 'all' failed
mingw32-make: *** [all] Error 2
The incriminated file is cap_dshow.cpp, and the compiler says that is missing the header file strsafe.h. Inside the folder C:\MinGW\include this file is not present and I don't know where to find this.
I've installed MinGW compiler (and other things) with a tool called "MinGW Installation Manager". With this tool I can install also other libraries, but I don't know if one of these contains the file strsafe.h.
My question is likely a duplicate of this, but the accepted answer has a broken link.
I have Microsoft SDK installed and found the strsafe.h file in "C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin".
Adding "C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin" to the Path system environment variable worked.
