\section{Building the library}

The library has been built and used successfully on several 
platform/architecture configurations and build systems.
Please see notes on specfic platforms to check if the target
architecture is currently supported.


\subsection{Requirements}

The following tools are supported directly to build the \product{dyncall} library.
However, as the number of source files to be compiled for a given
platform is small, it shouldn't be difficult to build it manually with
another toolchain.
\begin{itemize}
\item C compiler to build the \product{dyncall} library (GCC, Clang, SunPro or Microsoft C/C++ compiler)
\item C++ compiler to build the optional test cases (GCC, Clang, SunPro or Microsoft C/C++ compiler)
\item BSD make, GNU make, Microsoft nmake or mk (on Plan9) as automated build tools
\item Python (optional - for generation of some test cases)
\item Lua (optional - for generation of some test cases)
\item CMake (optional support)
\end{itemize}


\subsection{Supported/tested platforms and build systems}

Building \product{dyncall} is a straightforward two-step process, first configure, then make. The
library should be able to be built with the default operating systems' build tools, so BSD make on
BSD and derived systems, GNU make on GNU and compatible, mk on Plan9, nmake on Windows, etc..
This is a detailed overview of platforms and their build tools that are known to build
\product{dyncall}:\\

\end{lstlisting}% @@@ check Plan9, should work already
\end{enumerate}

\subsection{Build-tool specific notes}

Some platforms require some manual tweaks:

Problem: Build fails because CC and/or related are not set, or different compiler,
linker, etc. should be used.

Solution: Set the 'CC' and other environment variables explicitly to the desired
tools. E.g.:

\begin{lstlisting}
CC=gcc make
\end{lstlisting}


Problem: On windows using mingw and msys/unixutils 'Make', the make uses
'cc' for C compilation, which does not exist in mingw.

Solution: Set the 'CC' environment variable explicitly to 'gcc' (as in
the example above).

\subsection{Build with CMake}

\begin{lstlisting}
cmake -DCMAKE_INSTALL_PREFIX=<location>
make
\end{lstlisting}
