\section{Building wxPython}\label{wxpbuild}
I used SWIG (\urlref{http://www.swig.org}{http://www.swig.org}) to
to create the source code for the
extension module. This enabled me to only have to deal with a small
amount of code and only have to bother with the exceptional issues.
SWIG takes care of the rest and generates all the repetative code for
me. You don't need SWIG to build the extension module as all the
generated C++ code is included under the src directory.
I added a few minor features to SWIG to control some of the code
generation. If you want to play around with this you will need to get
a recent version of SWIG from their CVS or from a daily build. See
\urlref{http://www.swig.org/}{http://www.swig.org/} for details.
wxPython is organized as a Python package. This means that the
directory containing the results of the build process should be a
subdirectory of a directory on the {\tt PYTHONPATH}. (And preferably should
be named wxPython.) You can control where the build process will dump
wxPython by setting the {\tt TARGETDIR} variable for the build utility (see
below).
\begin{enumerate}\itemsep=0pt
\item Build wxWindows as described in its BuildCVS.txt file. For Unix
systems I run configure with these flags:
\begin{verbatim}
--with-gtk
--with-libjpeg
--without-odbc
--enable-unicode=no
--enable-threads=yes
--enable-socket=yes
--enable-static=no
--enable-shared=yes
--disable-std_iostreams
\end{verbatim}
You can use whatever flags you want, but I know these work.
For Win32 systems I use Visual C++ 6.0, but 5.0 should work also. The
build utility currently does not support any other Win32 compilers.
\item At this point you may want to make an alias or symlink, script,
batch file, whatever on the PATH that invokes {\tt \$(WXWIN)/utils/wxPython/distrib/build.py} to
help simplify matters somewhat. For example, on my Win32 system I have a file named
{\tt build}.bat in a directory on the PATH that contains:
{\tt python \%WXWIN/utils/wxPython/distrib/build.py \%1 \%2 \%3 \%4 \%5 \%6}
\item Change into the {\tt \$(WXWIN)/utils/wxPython/src} directory.
\item Type "{\tt build -b}" to build wxPython and "{\tt build -i}" to
install it, or "{\tt build -bi}" to do both steps at once.
The build.py script actually generates a Makefile based on what it
finds on your system and information found in the build.cfg file.
If you have troubles building or you want it built or installed in
a different way, take a look at the docstring in build.py. You are
able to to override many configuration options in a file named
build.local.
\item To build and install the add-on modules, change to the appropriate
directory under {\tt \$(WXWIN)/utils/wxPython/modules} and run the build
utility again.
\item Change to the {\tt \$(WXWIN)/utils/wxPython/demo} directory.
\item Try executing the demo program. For example:
{\tt python demo.py}
To run it without requiring a console on Win32, you can use the
{\tt pythonw.exe} version of Python either from the command line or from a
shortcut.

multiple sources. See

multiple sources. See
\urlref{http://wxpython.org/}{http://wxpython.org/} for details on
various sources of help, but probably the best source is the
wxPython-users mail list. You can view the archive or subscribe by
