OpenCV development team is working on port for Windows RT. Here is current development branch for WinRT. You can build it for ARM using Visual Studio Express for Windows 8 and Platform SDK (ARM versions of run time libraries are needed).

  1. Open Visual Studio development console.
  2. Setup environment for cross compilation by command "C:\Program Files\Microsoft Visual Studio 11.0\VC\bin\x86_arm\vcvarsx86_arm.bat"
  3. cd <opencv_source_dir>/platforms/winrt/
  4. run scripts/cmake_winrt.cmd
  5. run ninja

Alternatively you can use nmake instead ninja. You need to edit cmake_winrt.cmd and change project generator fro -GNinja to -G "NMake Makefiles". Only algorithmic part of the library is supported now, no tbb, no UI, no video IO.

Hi, I'm new to building stuff from source, I'm getting error while linking it. the link contains the error details..
Actually I did this using "vcvars32.bat", but when I did it using "vcvarsx86_arm.bat" it gave me

It would be really nice if you can help through this.

It look like arm versions of run time libraries are missing on your computer. You need to install the latest platforf SDK.

I have the latest platform SDK v8.0a installed.

What branch do you try to build? The right one is winrt.

after build, do we have to install it or something ? because the include folder doesn't contains the header files.

It is development branch. It is experimental and some features may not work. Installation can work incorrectly, I try to fix this issue in day or two. You need to do it manually.

Hi! Sorry for the trivial question but I'm having real problem with the build. Where should I run the scripts (scripts/cmake_winrt.cmd)? From <opencv_source_dir>/platforms/winrt/ (so >..\scripts/cmake_winrt.cmd) or in a new console?

In the first case I have to edit cmake_winrt.cmd changing the last line from cmake.exe ... -DCMAKE_TOOLCHAIN_FILE=..\winrt\arm.winrt.toolchain.cmake ..\ ..


cmake.exe ... -DCMAKE_TOOLCHAIN_FILE=..\winrt\arm.winrt.toolchain.cmake ..\ ..\ ..

otherway it can't find CMakeLists.txt But after I have maked this I got a lot of "Missing variable" from CMake
