CMake generated WindowsStore 8.0 ARM core module missing ole32.lib

[stammen]

How to reproduce:

setup_winrt.bat ws 8.0 arm build OpenCV.sln in bin/WS/8.0/ARM

core module generates the following error because linker input is missing ole32.lib.

1>------ Build started: Project: opencv_core, Configuration: Debug ARM ------ 1>LINK : warning LNK4075: ignoring '/INCREMENTAL' due to '/OPT:ICF' specification 1> Creating library D:/GitHub/opencv/bin/WS/8.0/arm/lib/Debug/opencv_core300d.lib and object D:/GitHub/opencv/bin/WS/8.0/arm/lib/Debug/opencv_core300d.exp 1>system.obj : error LNK2019: unresolved external symbol __imp_CoCreateGuid referenced in function __unwind$4 1>D:\GitHub\opencv\bin\WS\8.0\arm\bin\Debug\opencv_core300d.dll : fatal error LNK1120: 1 unresolved externals ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

On it. Preliminary investigation indicates that this might be a cmake platfrom configuration issue (lines 171,172):

 165 elseif(WINDOWS_PHONE OR WINDOWS_STORE)
 166   set(_PLATFORM_DEFINES "/DWIN32")
 167   set(_FLAGS_C " /DUNICODE /D_UNICODE")
 168   set(_FLAGS_CXX " /DUNICODE /D_UNICODE /GR /EHsc")
 169   if(WINDOWS_PHONE)
 170     set(CMAKE_C_STANDARD_LIBRARIES_INIT "WindowsPhoneCore.lib RuntimeObject.lib PhoneAppModelHost.lib")
 171   elseif(MSVC_C_ARCHITECTURE_ID STREQUAL ARM OR MSVC_CXX_ARCHITECTURE_ID STREQUAL ARM)
 172     set(CMAKE_C_STANDARD_LIBRARIES_INIT "kernel32.lib user32.lib")
 173   else()
 174     set(CMAKE_C_STANDARD_LIBRARIES_INIT "kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib")
 175   endif()
 176 else()

Configuration can be found locally at <cmake-installation-dir>\share\cmake-3.1\Modules\Platform\Windows-MSVC.cmake

You should probably check with Gilles.

Thanks,

Adding ole32.lib (line 172) in the Windows-MSVC.cmake configuration file shipped with cmake installations fixes the issue.

<path-to-cmake-installation-dir>\share\cmake-3.1\Modules\Platform\Windows-MSVC.cmake

- set(CMAKE_C_STANDARD_LIBRARIES_INIT "kernel32.lib user32.lib")
+ set(CMAKE_C_STANDARD_LIBRARIES_INIT "kernel32.lib user32.lib ole32.lib")

Regenerating OCV projects with

cmake 
  -G Visual Studio 12 2013 ARM 
  -DCMAKE_SYSTEM_NAME:String=WindowsStore 
  -DCMAKE_SYSTEM_VERSION:String=8.0 
  <path-to-cmake-src> 

or alternatively using wrapper script (ends up with the same command)

<path-to-cmake-src>/platfroms/winrt/setup_winrt.bat WS 8.0 ARM

makes it build successfully.

I added the missing ole32.lib for WindowsStore 8.0 in modules/core/CMakeLists.txt.

[khouzam]

Thanks. I'll see to get it add to CMake
