To get COLLADA support, you will also need to install the \texttt{collada-dom} packages or build them from scratch. Here, we install the \code{x86\_64} binaries and development headers included with Mitsuba:
inside the Mitsuba directory. In the case that you have multiple processors, you might want to parallelize the build by appending \code{-j }\emph{core count} to the command.
If all goes well, SCons should finish successfully within a few minutes:
\begin{shell}
scons: $\texttt{done}$ building targets.
\end{shell}
To be able to run the renderer from the command line, you will also have to import it into your path:
\begin{shell}
$\text{\$}$ . setpath.sh
\end{shell}
(note the period at the beginning -- this assumes that you are using \code{bash}).
\subsection{Building on Windows}
This section assumes that Visual Studio 2008 is installed, but the instructions should work equally well with other versions.
On the Windows platform, Mitsuba already includes most of the dependencies in precompiled form.
You will still need to set up a few things though: first, you need to install Python
(\url{www.python.org}) and SCons (\url{http://www.scons.org}) and ensure that they are contained
in the \code{\%PATH\%} environment variable so that entering \code{scons} on the command prompt
(\code{cmd.exe}) launches the build system (it will complain about not finding a project file though).
\emph{Note: }On some setups, the SCons installer generates a warning about not finding Python in the registry. In this case, you can instead run \code{python setup.py install} within the source release of SCons.
Next, install Qt (\url{http://qt.nokia.com/downloads/windows-cpp-vs2008} -- you should get the release for Visual Studio 2008). Again, you need to make sure that the
Qt utilities are reachable through the \code{\%PATH\%} environment variable so that you can for example launch \code{moc.exe} from the command line.
Because the official release of Qt currently only contains 32-bit binaries, you will accordingly have to
build Mitsuba in 32-bit mode (i.e. you should use the configuration file \code{config-msvc2005-win32.py}). If you would rather like compile it in 64-bit mode, you have to create
your own 64-bit Qt binaries.
Having installed these dependencies, run the ``Visual Studio 2008 Command
Prompt'' from the Start Menu (pick the \code{x86} version if you have the choice beetween \code{x86} and \code{x64}). Afterwards,
navigate to the Mitsuba directory and run \code{scons}.
In the case that you have multiple processors, you might want to parallelize the build by appending \code{-j }\emph{core count} to the \code{scons} command.
On Mac OS X, you will need to install both scons (\code{www.scons.org}) and
a recent release of XCode. You will also need to get Qt 4.7.0 Beta 2 or a newer version.
As of this writing, 4.7.0 Beta 2 is still the most recent release and can be found here: \url{http://qt.nokia.com/developer/qt-qtcreator-prerelease#download}
--- make sure that you get the normal Cocoa release (i.e. \emph{not} the one based on Carbon). All of the
other dependencies are already included in precompiled form.
Now open a Terminal and run
\begin{shell}
$\text{\$}$ scons
\end{shell}
inside the Mitsuba directory. In the case that you have multiple processors, you might want to parallelize the build by appending \code{-j }\emph{core count} to the command.
If all goes well, SCons should finish successfully within a few minutes:
\begin{shell}
scons: $\texttt{done}$ building targets.
\end{shell}
To be able to run the renderer from the command line, you will have to import it into your path:
\begin{shell}
$\text{\$}$ . setpath.sh
\end{shell}
(note the period at the beginning -- this assumes that you are using \code{bash}).
