Building the C++ library
The C++ library can be compiled with cmake.
The examples/samples/sample.cpp contains a minimal example that showcases the use of the parser.
Example of build commands under Linux:
$ cd nnef/cpp
$ mkdir build && cd build
$ cmake ..
$ make
Using the C++ library
Using the C++ parser is as simple as follows:
#include "nnef.h"
nnef::Graph graph;
std::string error;
bool success = nnef::load_graph("path/to/NNEF/folder", graph, error);
Upon succeess, the graph structure is filled, while in case of an error, the error string is filled. The fields inside the graph structure, and further parameters to the load_graph function are documented in nnef.h. After the graph is successfully loaded, shape inference can be performed in a subsequent call if required:
success = nnef::infer_shapes(graph, error);
Upon success, the shape fields of tensors are filled in.
