# TDLib C++ basic usage examples
|
||||
|
||||
TDLib should be prebuilt and installed to local subdirectory `td/`:
|
||||
```
|
||||
cd <path to TDLib sources>
|
||||
mkdir build
|
||||
cd build
|
||||
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX:PATH=../example/cpp/td ..
|
||||
cmake --build . --target install
|
||||
```
|
||||
Also, see [building](https://github.com/tdlib/td#building) for additional details on TDLib building.
|
||||
|
||||
After this you can build the examples:
|
||||
```
|
||||
cd <path to TDLib sources>/example/cpp
|
||||
mkdir build
|
||||
cd build
|
||||
cmake -DCMAKE_BUILD_TYPE=Release -DTd_DIR=<full path to TDLib sources>/example/cpp/td/lib/cmake/Td ..
|
||||
cmake --build .
|
||||
```
|
||||
|
||||
Documentation for all available classes and methods can be found at https://core.telegram.org/tdlib/docs.
|
||||
|
||||
To run the examples you may need to manually copy needed shared libraries from `td/bin` to a directory containing built binaries.
