# Getting Started

The TXT 4.0 includes everything needed for programming with C/C++. It comes
with *gcc* (version 8.2.0) as the compiler. The C and C++ headers are found
under */usr/include/ft*.

The entire [C API](c_interface.md) is included by

```C
#include <ft/ft.h>
```

and the [C++ API](cpp_classes.md) is included by

```Cpp
#include <ft/ft.hpp>
```



When compiling, one has to link the TXTControlLib.

```
gcc test.c -o test -lTxtControlLib
```

In order to be able to start the C/C++ programs from the GUI, the object file
has to be located in the */opt/ft/workspaces* directory (or in its
subdirectories). In the same folder, there must be a file with the same name
plus the ending *.c* or *.cpp*. This can be the actual source code or the file
can be completely empty.
