I got this problem when trying to compile opencv using Cmake and mingw.

for Cmake: sourcecode is located in "C:\CPP Libraries\OpenCV-2.4.13\opencv\sources" where the binaries are goint to be build is in: "C:/CPP Libraries/OpenCV-2.4.13/opencv/build/x64/mingw"

I've already used Cmake to generate the makefile.

when i run the makefile:

C:\CPP Libraries\OpenCV-2.4.13\opencv\build\x64\mingw>mingw32-make

this is the output that I get after 31%

[ 31%] Building CXX object modules/highgui/CMakeFiles/opencv_highgui.dir/src/window_w32.cpp.obj

Does anyone knows a solution, because i have no clue about this one.

it looks, like you're trying with an outdated mingw32 version.

rather get mingw64, and try again.

At 31% the build process is building the core module... the highgui module comes around 40%. Is this a successive build or did you remove some (relevant) modules ? Did you have any warning while configure/generate ?

Sincerely mingw32-make.exe is the make of mingw64. I can build OCV 2.4.13 with TDM-GCC-64 like a charm.

BTW, the BTNS_AUTOSIZE symbol is defined in <MINGW_ROOT>/x86_64-w64-mingw32/include/commctrl.h which is common include file for TDM-GCC-64.

window_w32.cpp:50 includes commctrl.h which is supposed to exist because your error is later. (or your builds doesn't have defined WIN32 || _WIN32)

Maybe your issue is from mingw / windows_32 libs... check if the file commctrl.h exists in your mingw installation and if it contains the symbols BTNS_AUTOSIZE.

You can also test it with a simple program like this:

#include <iostream>
#include <windows.h>
#include <commctrl.h>
using namespace std;

int main()
    int test = BTNS_AUTOSIZE;
    cout << "Test should be 16: " << test << endl;
    return 0;

at the end... check/update your mingw end ensure you have the windows_32 lib.

I also faced the same problem. I found the solution.

in the modules/highgui/src/window_w32.cpp

please add this lines between the #endif and the #include <commctrl.h> lines like this

#  pragma GCC diagnostic ignored "-Wmissing-declarations"

/*start new code lines*/
#if (_WIN32_IE < 0x0500)
#pragma message("WARNING: Win32 UI needs to be compiled with _WIN32_IE >= 0x0500 (_WIN32_IE_IE50)")
#define _WIN32_IE 0x0500
/*end new code lines*/   

#include <commctrl.h>
#include <stdlib.h>
#include <string.h>

Here is the original link I found here
