development and testing, and is meant to help other people that want
to do the same thing. I'll assume that you are using either a CVS
-snapshot from <a class="reference" href="http://wxwindows.org/snapshots/">http://wxwindows.org/snapshots/</a>, a checkout from CVS, or
+snapshot from <a class="reference" href="http://wxWidgets.org/snapshots/">http://wxWidgets.org/snapshots/</a>, a checkout from CVS, or
one of the released wxPythonSrc-2.5.* tarballs. I'll also assume that
you know your way around your system, the compiler, etc. and most
importantly, that you know what you are doing! ;-)</p>
<p>If you want to also install the version of wxPython you build to be in
your site-packages dir and be your default version of wxPython, then a
few additional steps are needed, and you may want to use slightly
-different options. See INSTALL.txt for more details. If you only use
-the instructions in this BUILD.txt file then you will end up with a
-separate installation of wxPython and you can switch back and forth
-between this and the release version that you may already have
-installed.</p>
+different options. See the <a class="reference" href="INSTALL.html">INSTALL</a> document for more details. If
+you only use the instructions in this <a class="reference" href="BUILD.html">BUILD</a> document file then you
+will end up with a separate installation of wxPython and you can
+switch back and forth between this and the release version that you
+may already have installed.</p>
<p>If you want to make changes to any of the <tt class="literal"><span class="pre">*.i</span></tt> files, (SWIG interface
definition files,) or to regenerate the extension sources or renamer
modules, then you will need an up to date version of SWIG. Either get
command-line variable named SWIG to be the full path name of the
executable and the wxPython build will use it. See below for an
example.</p>
+<p>In the text below I'll use WXDIR with environment variable syntax
+(either $WXDIR or %WXDIR%) to refer to the top level directory were
+your wxWidgerts and wxPython sources are located. It will equate to
+whereever you checked out the wxWidgets module from CVS, or untarred
+the wxPythonSrc tarball to. You can either substitute the $WXDIR text
+below with your actual dir, or set the value in the environment and
+use it just like you see it below.</p>
+<p>If you run into what appears to be compatibility issues between
+wxWidgets and wxPython while building wxPython, be sure you are using
+the wxWidgets sources included with the wxPythonSrc tarball or the CVS
+snapshot, and not a previously installed version or a version
+installed from one of the standard wxWidgets installers. With the
+"unstable" releases (have a odd-numbered minor release value, where
+the APIs are allowed to change) there are often significant
+differences between the W.X.Y release of wxWidgets and the W.X.Y.Z
+release of wxPython.</p>

so I'll combine the descriptions about their build process here.

+wxWidgets. If you want to have multiple builds with different
configure options, just use different subdirectories. I normally
put the configure command in a script named ".configure" in each
build dir so I can easily blow away everything in the build dir and
rerun the script without having to remember the options I used
before:</p>
<pre class="literal-block">

+ --enable-display \

<p>On OS X of course you'll want to use --with-mac instead of
--with-gtk. For GTK2 and unicode add:</p>
-<blockquote>
-<p>--enable-gtk2 --enable-unicode </p>
-</blockquote>
+<pre class="literal-block">
+--enable-gtk2 \

<p>Notice that I used a prefix of /opt/wx/2.5. You can use whatever
path you want, such as a path in your HOME dir or even one of the
standard prefix paths such as /usr or /usr/local if you like, but
using /opt this way lets me easily have multiple versions and ports

+of wxWidgets "installed" and makes it easy to switch between them,
+without impacting any versions of wxWidgets that may have been
installed via an RPM or whatever. For the rest of the steps below
be sure to also substitute "/opt/wx/2.5" with whatever prefix you
choose for your build.</p>
<p>If you want to use the image and zlib libraries included with
-wxWindows instead of those already installed on your system, (for
+wxWidgets instead of those already installed on your system, (for
example, to reduce dependencies on 3rd party libraries) then you
can add these flags to the configure command:</p>

".make" (I use the leading ". so when I do <tt class="literal"><span class="pre">rm</span> <span class="pre">-r</span> <span class="pre">*</span></tt> in my build

<p>We're not going to install the development version of wxPython with

<p>If you have more than one version of Python on your system then be
sure to use the version of Python that you want to use when running
wxPython programs to run the setup.py commands below. I'll be
using python2.3.</p>

these file extensions) and it will launch the Framework version of
Python for you. For information about creating Applicaiton Bundles
of your wxPython apps please see the wiki and the mail lists.</p>
to accomodate that. (And send the patches to me.) If you plan on
using VisualStudio.Net (a.k.a. MSVC 7.1) keep in mind that you'll also
have to build Python and any other extension modules that you use with

+<p>If you want to build a debuggable version of wxWidgets and wxPython you
will need to have also built a debug version of Python and any other
extension modules you need to use. You can tell if you have them
already if there is a _d in the file names, for example python_d.exe
version is fine, and you can use the regular python executables with
it.</p>
<p>Just like the unix versions I also use some scripts to help me build
-wxWindows, but I use some non-standard stuff to do it. So if you want
-to use them too you'll need to get a copy or 4DOS or 4NT from
-<a class="reference" href="http://www.jpsoft.com/">http://www.jpsoft.com/</a> and also a copy of unix-like cat and sed

-there are a lof steps involved and I won't be going into details

+wxWidgets, but I use some non-standard stuff to do it. So if you have
+bash (cygwin or probably MSYS too) or 4NT plus unix-like cat and sed
+programs then there is a copy of my wxWidgets build scripts in
+%WXDIR%\wxPython\distrib\msw. Just copy them to
+%WXDIR%\build\msw and you can use them to do your build, otherwise
+you can do everything by hand as described below. But if you do work
+by hand and something doesn't seem to be working correctly please
+refer to the build scripts to see what may need to be done
+differently.</p>
+<p>The *.btm files are for 4NT and the others are for bash. They are:</p>
