# Tonlib C++ basic usage examples Tonlib should be prebuilt and installed to local subdirectory `tonlib/`: ``` cd mkdir build cd build cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX:PATH=../example/cpp/tonlib .. cmake --build . --target install ``` Then you can build the examples: ``` cd /example/cpp mkdir build cd build cmake -DCMAKE_BUILD_TYPE=Release -DTonlib_DIR=/example/cpp/tonlib/lib/cmake/Tonlib .. cmake --build . ``` To run `tonjson_example` you may need to manually copy a `tonlibjson` shared library from `tonlib/bin` to a directory containing built binaries.
