OpenCV example Visual Studio 2017 #483

Closed akeilox closed 7 years ago

akeilox commented 7 years ago

I am trying to compile the OpenCV example on Visual Studio 2017 with c++ dev installed.

During build it complains cant locate the opencv_core300d,lib which I presume needs to be compiled from ms opencv fork at https://github.com/Microsoft/opencv

but I cant get that fork to compile under Visual Studio 2017 either, enquired the same under https://github.com/Microsoft/opencv/issues/78

Is there any fellow VS 2017 user who manage to get the OpenCV to compile/work on the windows IOT?

following up on the post above, i might have a hacky progress but still falls short;

after installing c++ dev tools for vs 2015, the project openCV still did not compile. So I have tried renaming all the references from 140 to 141 in the .vcxproj files

After which I have changed the SDK version of the openCV fork to 10.0.15 (latest)

then i have compiled both debug and release versions for ARM and x86, to get the libs (w/o ..d) build.

After all of the above 'hacks' i was able to compile the openCV for arm and x86 within VS 2017.

Finally I have build the OpenCV iot example, built went fine with no errors, but noticed it complains about App being started but activation request failed - when i try to release/debug it to Raspberry Pi 3 running latest IOT - assuming there is a trick here im missing? Hopefully someone can clarify.

Exact error when debugging on remote machine, after transferring the app;

Unable to activate Windows Store app '4277356b..........' The OpenCVExample.exe process started but the activation request failed with error 'The app didnt start' under output log: OpenCVExample.exe' has exited with code -1073741515 (0xc0000135) 'A dependent dll was not found'. with no mention of which dll its about.

Would appreciate if someone can shed light on this.

Hi @akeilox , Please research this with the repository owners at https://github.com/Microsoft/opencv/issues Sincerely, IoTGirl

@IoTGirl We need to have opencv_core300d.lib and opencv_core300,lib available through Nuget. So others do not have to repeat the the process of how to get it works
