Can't compile

[diogocaribe]

I tried to compile gdal-segment, but one error raise every time. So, I couldn't acheive

Follows the code that I used and the error.

What I did that cause this problem? What can I to fix it?

• Also for

Could NOT find OpenCV (missing: hdf) (found version "3.3.1")

You need opencv-contrib (opencv's extra package). The rest of openmp related messages are waveable.

[diogocaribe]

But why? I compiled it when I put this "cmake CMAKE_VERBOSE=1 -DOPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules"

Or not?

[cbalint13]

• Then it sounds like opencv_contrib misses hdf module. Please recompile opencv+opencv_contrib with hdf5. Make sure you have hdf installed and opencv accepts it during cmake.

[diogocaribe]

Do sudo apt-get install hdf5-tools is enough?

[cbalint13]

I believe you need apt-get install hdf5-dev (the development package). Not familiar with .deb (debian, ubuntu) systems.

Thank you. When I solve the problem I will write it here.
