How to compile a C++ application that depends on OpenCV

[BrayanAlfaro]

Hi,

I want to compile a C++ application that requires OpenCV. Is OpenCV available on DevCloud? What should be the include path to compile with g++? And how do I link the executable to the OpenCV libraries?

Thanks

Hi,

Thank you for posting in Intel Communities. Could you please let us know which DevCloud you're using? Is it DevCloud for oneAPI or DevCloud for Edge or DevCloud for FPGA?

Hi,

It's DevCloud for oneAPI. So far, the only solution I've found is building OpenCV locally. Is there another way to use OpenCV in DevCloud for oneAPI?

Thanks,

Brayan

Hi,

OpenCV does not fall under the scope of oneAPI DevCloud. As such we will not install it.

oneAPI DevCloud users have the opportunity to build it from source.

Here's a general idea of the steps you can take in order to build it from source:

git clone https://github.com/opencv/opencv.git

cd opencv

mkdir build

cd build

cmake -D INSTALL_PYTHON_EXAMPLES=ON -D INSTALL_C_EXAMPLES=ON ..

make -j$(nproc)

More info on the OpenCV official pages: https://docs.opencv.org/4.x/d7/d9f/tutorial_linux_install.html

If this resolves your issue, make sure to accept this as a solution. This helps others with similar issue.
