Build the C++ package

The C++ package has the same prerequisites as the MXNet library.

To enable C++ package, just add USE_CPP_PACKAGE=1 in the build from source options when building the MXNet shared library.

For example to build MXNet with GPU support and the C++ package, OpenCV, and OpenBLAS, from the project root you would run:

make -j USE_CPP_PACKAGE=1 USE_OPENCV=1 USE_BLAS=openblas USE_CUDA=1

You may also want to add the MXNet shared library to your LD_LIBRARY_PATH:

export LD_LIBRARY_PATH=~/incubator-mxnet/lib

Setting the LD_LIBRARY_PATH is required to run the examples mentioned in the following section.

C++ Example Code

You can find C++ code examples in the cpp-package/example folder of the MXNet project. Refer to the cpp-package's README for instructions on building the examples.
