Steps for Building OpenCV Static Libraries in Win7

Versions:

• OpenCV 3.1.0-dev
• CMake 3.7.0-rc2-win32-x86
• TDC-GCC 5.1.0-tdm-1
• Python 2.7

First, in CMake...

　Step 01: Uncheck 'BUILD_SHARED_LIBS' 

　Step 02: Uncheck 'BUILD_opencv_python2' 

　Step 03: Set the value of 'CMAKE_EXE_LINKER_FLAGS' to '-static'.

　then, do 'Configure' several times until all red background disappeared.

　and then, 'Generate' the make file for compiler.

Second, in command shell (Microsoft Powershell could be better)...
　Step 01: change your working directory to 'C:\OpenCV\build\'

　Step 02: run 'mingw32-make'

　Step 03: run 'mingw32-make install'

Third, in Code Blocks...

　Step 01: add all *.a file in folder 'C:\OpenCV\build\install\x86\mingw\staticlib' into 'Link Libraries:'.

　Step 02: add next 5 lines into 'Other Linker options:'.

　　　　　　-static
　　　　　　-static-libgcc
　　　　　　-static-libstdc++
　　　　　　-Wl,--start-group
　　　　　　-mwindows'

　Step 03: set 'Search directories of Compiler' to 'C:\OpenCV\build\install\include'.

　Step 04: set 'Search directories of Linker' to 'C:\OpenCV\build\install\x86\mingw\staticlib'.

　then, build and run your code.
