windows: OpenCV 4.3.0 build failing on generating vs_version.rc using mingw-w64

[deadprogram]

System information (version)

• OpenCV => 4.3.0
• Operating System / Platform => Windows 64-bit
• Compiler => mingw-w64 v7.3.0

Detailed description

Our current build script fails on our Appveyor CI build when we update to OpenCV 4.3.0. Not sure about the origin of this issue. Thanks for any help.

Steps to reproduce

See https://ci.appveyor.com/project/deadprogram/gocv/builds/31965264#L1242

[dkurt]

Please add full log including cmake step.

[alalek]

Please dump compiler command line options: make VERBOSE=1

Allocator metrics storage type: 'long long'

Perhaps this one is related (see #16786). Try to pass:

cmake -DOPENCV_ALLOCATOR_STATS_COUNTER_TYPE=int64_t ...

[deadprogram]

@dkurt here is the CMake step: https://github.com/hybridgroup/gocv/blob/feature/opencv-4.3.0/appveyor_build_opencv.cmd#L15

[deadprogram]

Hi @alalek adding the -DOPENCV_ALLOCATOR_STATS_COUNTER_TYPE=int64_t option to CMAKE allows the build to complete.

If this is covered by #16786 then should I close this issue?

[alalek]

Feel free to propose patch with default value for mingw here (to 3.4 branch).

CMake generator: MinGW Makefiles

Also it might that this CMake generator doesn't handle spaces in definitions well (this generator is used rarely with CMake).
Consider using "ninja" if it is supported by AppVeyor environment.

[deadprogram]

OK, sounds good. I will look into if there is a coherent patch I could submit, or possibly switching to ninja.

Now closing this issue, thanks very much @alalek and @dkurt for quick response.

@alalek when in the cmake-gui , to add the entry, which type should i select (BOOL or STRING ). And should i check the value box. Thanks

Hi, @alalek , i used mingw32-make to build opencv3.4 and contrib and have an error like oben:gcc error: No such file or directory and then i have added OPENCV_ALLOCATOR_STATS_COUNTER_TYPE = int64_t in cmake:

and have another problem:
Could you tell me what happends hier and how to solve this problem? Thanks a lot.

Hi, @yiyayiyau i am getting the same errors. I could not find the solution. Can you share if you found the solution? Thanks a lot.
