6 \chapter{Invoking the \faust compiler}
7 The \faust compiler is invoked using the \texttt{faust} command. It translate \faust programs into C++ code.
8 The generated code can be wrapped into an optional \emph{architecture file} allowing to directly produce a fully operational program.
9
10 \begin{rail}
11 compiler : "faust" (options) (file +);
12 \end{rail}
13
14 For example \lstinline'faust noise.dsp' will compile \lstinline'noise.dsp' and output the corresponding C++ code on the standard output. The option \lstinline'-o' allows to choose the output file : \lstinline'faust noise.dsp -o noise.cpp'. The option \lstinline'-a' allows to choose the architecture file : \lstinline'faust -a alsa-gtk.cpp noise.dsp'.
15
16 To compile a \faust program into an ALSA application on Linux you can use the following commands:
17 \begin{lstlisting}
18 faust -a alsa-gtk.cpp noise.dsp -o noise.cpp
19 g++ -lpthread -lasound
20 `pkg-config --cflags --libs gtk+-2.0`
21 noise.cpp -o noise
22 \end{lstlisting}
