OpenCV3 Linux support: Error compiling OpenCvSharpExtern #377

Closed zandam-xrn closed 4 years ago

zandam-xrn commented 7 years ago

Summary of your issue

I've tried to compile OpenCvSharpExtern on Linux where I've already installed OpenCv3 with Cuda acceleration. I need to maintain OpenCv3 alignment between developement workstation (Windows Visual Studio OpenCv3) with the deployment machine (Linux OpenCv3).

Environment

Linux keypc01 4.9.36-aufs #2 SMP Fri Aug 11 18:11:18 UTC 2017 x86_64 Intel(R) Core(TM) i5-7600K CPU @ 3.80GHz GenuineIntel GNU/Linux.

OpenCv 3.2.0 System GCC 6.4.0 Cuda GCC 5.4.0 Mono 4.8.0.524

What did you do when you faced the problem?

Compiling OpenCvSharpExtern (make).

Output:

                 from /opencvsharp/src/OpenCvSharpExtern/aruco.cpp:1:

I moved forward trying to fix this error. The main issue was that the opencv files in my system had a different path, so I edited this file: /Data/Dev01/opencvsharp/opencvsharp/src/OpenCvSharpExtern/include_opencv.h with the right opencv2 files location and this error: /Data/Dev01/opencvsharp/opencvsharp/src/OpenCvSharpExtern/include_opencv.h:28:45: fatal error: /usr/include/opencv2/tracking.hpp: No such file or directory looks like solved.

But then I encountered this error message: 

In file included from /opencvsharp/src/OpenCvSharpExtern/aruco.h:4:0,
                 from /opencvsharp/src/OpenCvSharpExtern/aruco.cpp:1:

 #include </usr/include/opencv2/xfeatures2d.hpp>
                                                ^
compilation terminated.
make[2]: *** [OpenCvSharpExtern/CMakeFiles/OpenCvSharpExtern.dir/build.make:63: OpenCvSharpExtern/CMakeFiles/OpenCvSharpExtern.dir/aruco.cpp.o] Error 1
make[1]: *** [CMakeFiles/Makefile2:86: OpenCvSharpExtern/CMakeFiles/OpenCvSharpExtern.dir/all] Error 2
make: *** [Makefile:130: all] Error 2

So apparently the previous error on the tracking.hpp file has been solved and the make instruction failed few lines later. Since the opencv2/xfeatures2d.hpp file does not exist in my system I tried to comment out that failing line from the include_opencv.h file and I tried to compile the code again. This time the process reached 76% and then failed with this error:

I was able to get the extern library to build by building openCV and openCV contrib. In ./src/CMakeLists.txt I had to add two lines for opencvsharp. include_directories("/usr/local/include/") set (CMAKE_CXX_STANDARD 11)

johncharris commented 7 years ago

I haven't tested this since I cleaned it up, but I just installed this on a docker image with dotnetcore 2.0 and these are the steps I went through.

Right at the very end it will say that several of the target didn't build. That's fine since it builds both the dotnetcore1.0 assembly and the netstandard 1.4 assembly.

To use this outside of Docker, sudo will be needed in a few places.

Thanks for the reply. I'll try your suggestion asap and I'll post the results here.

johncharris commented 7 years ago

I updated the script in my previous comment.

DaEkstrim commented 7 years ago

@johncharris Can your script be used for ARM architecture? I'm asking because I tried your above script and I ran into some error during make namely:

/home/master/src/opencvsharp/src/OpenCvSharpExtern/my_types.h:310:8: error: ‘struct cv::aruco::DetectorParameters’ has no member named ‘doCornerRefinement’; did you mean ‘cornerRefinementMethod’?
     pp.doCornerRefinement = p.doCornerRefinement != 0;
        ^~~~~~~~~~~~~~~~~~
DaEkstrim commented 7 years ago

I believe I know what I did... I installed opencv3.3 and opencvsharp targets 3.2. Correct me if I'm wrong.

Edit: It worked on RPI Raspbian Stretch. Thank you @johncharris
Edit: For future readers, I wrote my notes in this issue: https://github.com/shimat/opencvsharp/issues/388#issuecomment-337953321
