I use OpenCV3-beta in Eclipse under Win8.1 and have to build source from git since there are no minGW libs available for download. It was ok before, but today(just now) I updated all sources and now mingw32-make suddenly fails:
\git\opencv\modules\highgui\src\window_w32.cpp:2011:9: error: 'TBBUTTONINFO' was not declared in this scope
It is not the only error, there are some another errors which is similar to mentioned above:
\git\opencv\modules\highgui\src\window_w32.cpp:2023:81: error: 'BTNS_AUTOSIZE' was not declared in this scope
\git\opencv\modules\highgui\src\window_w32.cpp:2023:97: error: 'BTNS_BUTTON' was not declared in this scope
