	13	<p>This document will describe the few differences and additions to the
	14	content in the <a class="reference" href="BUILD.html">BUILD</a> document for installing wxPython built from
	15	source. Please follow the intstructions both in this file and in
	16	<a class="reference" href="BUILD.html">BUILD</a> to perform this task. Where there is overlap the items
	17	described here will take precedence for doing installations.</p>

	21	<li><p class="first">When building wxWidgets you need to decide if you want it to be a
	22	private copy only accessed by wxPython, or if you would like it to
	23	be installed in a stanard location such as /usr. Or perhaps you
	24	already have a version of wxWidgets installed on your system (such
	25	as from an RPM) and you want wxPython to use that version too. If
	26	so then you'll want to ensure that the flags and options used to
	27	build the installed version are compatible with wxPython.</p>
	28	</li>
	29	<li><p class="first">If you do decide to build and install your own wxWidgets then there
	30	are a few tweaks to the configure flags described in BUILD.txt that
	31	you will probably want to make. Instead of --enable-debug use
	32	this configure flag:</p>
	33	<pre class="literal-block">
	34	--enable-optimize \
	35	</pre>
	36	<p>Normally I also use the following flag in order to have wxWidgets
	37	runtime assertions turned into Python exceptions where possible.
	38	It does add extra code to the build but probably not enough to
	39	worry about it. However if you want to get as lean a build as
	40	possible you can leave it out, but if your code does something bad
	41	then instead of exceptions you'll likely get a crash:</p>
	42	<pre class="literal-block">
	43	--enable-debug_flag \
	44	</pre>
	45	<p>If you are building a private copy of wxWidgets (IOW, not installed
	46	in a standard library location) then it can be kind of a hassle to
	47	always have to set the LD_LIBRARY_PATH variable so wxPython can
	48	find the wxWidgets shared libraries. You can hard code the library
	49	path into the binaries by using the rpath option when configuring
	50	wxWidgets. For example:</p>
	51	<pre class="literal-block">
	52	--enable-rpath=/opt/wx/2.8/lib \
	53	</pre>
	54	<p>SOLARIS NOTE: The --enable-rpath option may cause problems when
	55	using wxGTK on Solaris when compiling wxPython as described below.
	56	The woraround is to not use --enable-rpath flag for configure, but
	57	in that case all wxPython applications <em>must</em> have the
	58	LD_LIBRARY_PATH set to include $WXPREF/lib, or you can use the
	59	'crle' program to modify the runtime linking environment. If this
	60	is the only installation of wxGTK on the system then you can use a
	61	system library path for prefix and not have to worry about it at
	62	all.</p>
	63	</li>
	64	<li><p class="first">Build and install wxGTK as described in BUILD.txt.</p>
	65	</li>
	66	<li><p class="first">In addition to building wxPython as described in BUILD.txt, you can
	67	install it to Python's site-packages dir, as well as some scripts
	68	into the same bin dir used by Python by using this command, plus
	69	whatever WXPORT, UNICODE, etc. settings you used for the initial
	70	build step:</p>
	71	<pre class="literal-block">
	72	python2.5 setup.py install
	73	</pre>
	74	<p>If you would like to install to some place besides the prefix where
	75	Python is installed, (such as to your home directory) then you can
	76	add "--root=<path>" after the "install" command. This will use
	77	<path> as the prefix and will install scripts to a bin subdir and
	78	the wxPython packages to a lib subdir. To use wxPython like this
	79	you'll need to ensure that the directory containing wxPython is
	80	contained in the PYTHONPATH environment variable.</p>

	85	<h1><a id="installing-on-os-x" name="installing-on-os-x">Installing on OS X</a></h1>
	86	<p>Installing wxPython on OS X is nearly the same as the Unix
	87	instructions above, except for a few small, but important details:</p>
	88	<ol class="arabic simple">
	89	<li>The --enable-rpath configure option is not needed since the path to
	90	the wxWidgets dylibs will automatically be encoded into the
	91	extension modules when they are built. If you end up moving the
	92	wxWidgets dynlibs to some other location (such as inside the .app
	93	bundle of your applicaiton for distribution to other users,) then
	94	you will need to set DYLD_LIBRARY_PATH to this location so the
	95	dylibs can be found at runtime.</li>
	96	<li>Depending on the version of OS X Python may be installed in
	97	different locations. On 10.2 (Jaguar) you need to download and
	98	install MacPython-OSX-2.3 from <a class="reference" href="http://www.python.org/">http://www.python.org/</a> and the
	99	Python Framework will then be installed in /Library/Frameworks. On
	100	10.3 (Panther) Apple supplies the Python Framework as part of the
	101	OS install, but it will be located in /System/Library/Frameworks
	102	instead. However, on Panther the site-packages dir is sym-linked
	103	to /Library/Python/2.3 so the wxPython packages will end up there,
	104	although they will still be visible from site-packages. If you are
	105	building distributions of wxPython to be installed on other
	106	machines be careful to install to /Library/Python/2.3. To
	107	complicate things further, the Jaguar version, or a custom build
	108	you do yourself will end up in /Library/Frameworks even on
	109	Panther...</li>
	110	<li>You need to use pythonw at the command line or the PythonLauncher
	111	app to run wxPython apps, otherwise the app will not be able to
	112	fully use the GUI display.</li>

	118	<li><p class="first">Build wxWidgets and wxPython as described in BUILD.txt. If you
	119	would rather have a version without the code that turns runtime
	120	assertions into Python exceptions, then use "release" instead of
	121	"hybrid" when building wxWidgets and add "FINAL=1" to the setup.py
